Since its foundation, Toray has adhered to the philosophy that “R & D is the key to the Toray of tomorrow.” With this in mind, the company has continually focused its efforts on research and technological development (R & TD), making the strengthening of basic research and fundamental technologies an important management issue, and has proceeded to create new technologies and technological areas. Toray also clearly distinguishes between its research activities and development activities, placing priority on highly innovative basic and exploratory research.

Down has the highest warmth to weight ratios of any insulation material.  The only draw back to down is moisture, once wet down looses all of its performance and has very long drying times. This is the reason down is rarely used or recommended in hunting apparel.

Through nano-technology Toray has created a water repellent finish for down feathers called Quixdown that makes a feather essentially waterproof. Toray’s Quixdown now eliminates the need for synthetic insulation which is significantly heavier, bulkier and not nearly as warm as down.

KUIU will be introducing several new Quixdown Filled garments next month called Super Down. These new garments are lighter warmer and more comfortable than any insulation product ever introduced. We sourced down from Poland which is the highest grade down in the world with a 92% Down and only 8% feather ratio! Our fill rating in our Super Down garments is over  850!

More to come on KUIU’s Super Down Line later this month. Enclosed is a video demonstration of Quixdown for your review.

    Cool…Been waiting for this one since you left the proto type with Kent!!!!

    I am especially excited about these pieces as I’ve always been a HUGE fan of down but always steered away from down garmets for hunting due to the lack of water proofing. 850 fill rate…AWESOME! Bring ’em on!!!!!

    • Jason Hairston

      Thanks Cory! Our Superdown line is next level stuff for sure. I will have a post on the garments next week.


  2. Kody

    Put me on the preorder list!

    • Jason Hairston

      The list is coming!

  3. Will Jenkins

    Very Cool! Sounds like a great product!

    • Jason Hairston

      It is awesome. Wait until you see the new fabric Toray developed we are putting in!


  4. Brady Miller

    You nailed it with this one. Going to be a HUGE hit!!

    • Jason Hairston

      Thanks Brady!!

  5. Ken Anderson

    This is a very exciting development! I know that many water repellent products become less effective over time due to soiling and most especially washing/laundering. Any idea how durable the Quix Down finish will be?

    • Jason Hairston

      Hi Ken,

      Great question. As with any water repellent finish washing can diminish the effectiveness. If you research Toray’s DWR is has the highest durability in the world. Significantly more durable than its closest competitor. This is the same with the Quix Down. As with any down garment or sleeping bag you want to avoid washing unless you have to is always recommended to preserve the loft of down.


  6. Will Ramos


    Really excited about this product. Couple of questions. Is the treatment on the down permanent or does it degrade overtime? Is it machine washable?

    • Jason Hairston

    You’re killing me Jason. That sounds like a great insulating garment that I must convince my wife that I need 🙂

    I love down, but wear my thin Primalot coat instead of down often prior to Nov 15 because of the rain.

    What about a Kuiu Quix Down jacket with the option of an attachable hood for glassing? I think that would be my perfect jacket for any hunt and weather when added to a waterproof breathable shell.

    • Jason Hairston

      Hang on Mike:) I will announce the products and styles in Quix Down soon here on the blog.


  8. JC

    what? Poland!@!@

    OK, enough of that…

    Always been a down guy…actually the Spindrift was the first synthetic insulation I’ve bought in a looong time. Are you gonna put this stuff in a sleeping bag? You should think about Toray shelled, Superdown filled bag, you could almost eliminate the need for a tent all together!

    • Jason Hairston

      Yes it is in development.

  9. Matt Alford

    This sounds GREAT! Looking forward to it.


    • Jason Hairston

      Thank you Matt!

  10. David

    Jason very impressive. As always keep up the great progress of striving forward. By the way, I’m likening the new verde pattern.

    • Jason Hairston

      Thank you David!! I really appreciate it.


  11. Shane Close

    Sounds awesome! When are they going to be available to purchase?

    • Jason Hairston

      Mid-Novemberish. Pre orders sooner. I will announce this on the blog soon.


  12. eburgsnake

    Can’t wait to see the new products. Hard to imagine a jacket I like more the the Spindrift, but maybe this’ll be it?

    • Jason Hairston

      You will, trust me.


  13. Ben Stourac

    INCREDIBLE! While everyone else is trying to figure out waterproof layering to cover the down, Kuiu waterproofs the down itself. Interesting to see how long the Quix Coating will last on the down though.

    • Jason Hairston

      Thanks Ben. We have had fantastic results in testing this garment and the durability has not been an issue regarding the performance of the Quix Down. As with any high quality down garment we do recommend avoiding washing unless you have to to preserve the loft of the down.


  14. Steve Herndon

    Jason, that sounds great. I am using primaloft from Sitka and really like it. How will this new Quix down compare as far as weight, warmth and more importantly price?

    • Jason Hairston

      It will weigh about 1/3 of the weight of the Kelvin, be warmer, pack down to about 1/3 the size and will cost about the same or less depending on which garment you buy from us. I will have more on our specific products soon.


  15. Craig Germond

    Sounds like the CC is going to take another hit! Can’t wait to see the new items!

    • Jason Hairston

      Yes this is next level product that is coming!!

  16. Wade Musick

    Do you know if the down is hyper allergenic? I have wore down several years ago and it bothered my allergies. Sounds like an awesome product. Love the new verde line.

    • Jason Hairston

      Hi Wade,

      It is not. Thanks for the compliments on the Verde.


  17. Kevin

    Very cool. And well done with the demonstration, pretty powerful visual. I have a couple hunts in Nov and Dec I’m helping on so bring on the preorder date. I also second the waterproof degration and machine washable questions. Exciting stuff.

    • Jason Hairston

      Same answer as above. As with any water repellent finish washing can diminish the effectiveness. If you research Toray’s DWR is has the highest durability in the world. Significantly more durable than its closest competitor. This is the same with the Quix Down. As with any down garment or sleeping bag you want to avoid washing unless you have to is always recommended to preserve the loft of down.


  18. Seth

    Sounds ideal. A lightweight fabric with a tight enough “down proof” weave will be key. I’m sure Toray will nail it. Looking forward to it.

    • Jason Hairston

      Thanks Seth. Just think if the fabric could stretch too?

  19. Kevin Osberg

    I’ll go watch the video now, so I apologize if this question gets answered there, but how will this compare to the Primaloft in the Spindrift? I absolutely loved my Spindrift when getting up at 4am on my elk hunt this fall, so I’ll be curious to see how things could get even better.

    • Kevin Osberg

      Also, I’m sure you don’t want to reveal all the plans for the Quix down, but please tell me there’s a sleeping bag on the way or it’s at least on your mind!

      • Jason Hairston

        Yes, in development.

  20. Cameron Meier


    Do you know the fill weight of the jacket? I assume probably 2-4 oz. Also I am guessing the new products will be a jacket, vest and maybe pants?

    • Jason Hairston

      Hang on Cameron, more to come on the specific products soon!!

  21. Eric Bergey

    Jason, your making me poor. But I love it.

    • Jason Hairston

      LOL!!!! Thanks for the comment!!

  22. Larry Schwartz

    Some down pants to go with a jacket would be just the ticket for long periods of glassing on cold and windy ridges, as well as what all the treestand hunters have been longing for. I just wonder if the down in the seat of the pants would still keep you warm when it is compressed.

    BTW, my research on Primaloft, which could be faulty, showed that it didn’t get much higher than an equivalent 650 down fill weight, so this should be much warmer than the Spindrift.


    • Jason Hairston

      I would recommending standing up if your butt gets cold:) It depends how much down is in the garment. We will have a couple of choices to choose from depending on the hunt and weather conditions.


  23. Woody

    I am personally going to let some other people play guinea pigs on this one for a bit before I invest.

    • Jason Hairston

      I would not wait too long. This is the best product I have tested and highly recommend it to all of our customers.

  24. Mike

    Wow Jason sounds and looks AWESOME!! I’m in!

    • Jason Hairston

      It is AWESOME!!!!!!!!!

  25. Kevin Dill

    Having always been a goose down user, I’m very interested to see the design of these garments. Waterproof down will be a huge hit…a slam dunk, pardon the pun. Thanks for continuing to innovate and explore the boundaries Jason!

    • Jason Hairston

      Thanks Kevin! I said the same thing to Toray when they introduced this technology to me. This is a Slam Dunk in the hunting industry!


  26. heron163

    can’t wait – hope it comes in time for late season whitetails

    • Jason Hairston

      It is coming next month.


  27. Ken Allen

    Amazing – This is an awesome development – Lightweight insulation that helps you to stay warmer and glass longer. It’s a lot easier to stay out longer when you are warmer and you can only pack and put on so many layers. I am really happy to see this product!!!!!!! Any chance that we will see a KUIU sleeping bag with this product? I now use a helium bag with water resistant fabric but I still worry in really wet conditions that it will give up. Gloves would be awesome too!

    • Jason Hairston

      Yes Ken, a bag is currently in development!


  28. Jason

    J – this could be a major GAME CHANGER!

    I look forward to the products.

    • Jason Hairston

      Is a major game changer. Wait till you see the products.


  29. Steve Herndon

    Thanks Jason. I have a guide jacket on order in the Vias camo in xl, I lost my jetstream jacket on my elk hunt this year and want to try the Kuiu, my question is the xl in the jetstream fit great had plenty of room in the arms for archery. Will the guide jacket fit the same or should I change to a large. I would really like to start using more of your gear but everything is always on backorder. BTW, the Kuiu gear i have is great!!

  30. Neal Zeller

    Does the nano tech add any weight to the down vs. untreated down? I’m a total gram geek. Otherwise, sounds like a remarkable prod. I second the sleeping bag development.

  31. Justin Starck

    That’s what I want!

    • Jason Hairston

      This is RIGHT in your wheelhouse! I knew you would like this one!

      • Justin Starck

        Now KUIU really can build the perfect layering system!

      • Justin Starck

        I finally watched the demonstration; it’s even more impressive than I imagined it would be. I am really excited to get some. My old down might not get used all that much…

  32. Edwin Gordon

    I’ll have to get one in camo and one in East Coast civilian…Great job, Jason. After the Spindrift, can’y wait to see the Quix Down. Keeping evolving!


  33. Matt N

    Please make a warm one for late season big gamers and duck hunters. There are zero quality lightweight jackets out there now. I’m hoping for something warmer than a down sweater. Glassing for rutting muleys in the open country wind takes a big jacket with a good hood. Currently use a DAS parka military prototype that is too big.

    • Jason Hairston

      We have one coming. More on the products next week.


  34. Alex Einspruch

    Price wise will you do better than Patagonia? I’m in need of down insulation and their down sweater is looking pretty warm, although completely the wrong color, but it will be layered under my Guide Jacket!

    Looking forward to this announcement Jason.

    • Jason Hairston

      Better in Quality, Innovation and Price.

  35. Russ

    Been a big fan of down for years (Western Mountaineering and Montbell). Nothing better for a long cold glassing session than a big puffy down coat! Nice to see a hunting apparel company be on the leading edge for a change, rather than mimicking the mountaineering crowd.

    Treat down well and it will last for years. I have a well used WM Flight jacket that weighs 13 ounces (XL), packs about 30% smaller than my Spindrift and is easily 2x warmer. After 8 years there is little to no loss in performance that I can tell. Some of my down sleeping bags are 10+ years old with only minimal loss of loft.

    That said, I treat my down carefully. The Spindrift is much more suited to rugged abuse. And when you get home you can just toss it in the washer.

  36. Mathew D’Ath

    This is going to be a must for most of us,I hope a sleeping bag is coming too,Can’t wait to see the list

    • Jason Hairston

      In development.

  37. Pedro Ampuero

    Again… FUCKING AWESOME!!!!! Defiant Troublemaker, so true!!

    You see some brands calling improvement to changing some pocket locations… these are huge concept improvements. Thanks for sharing it with all of us, its nice to understand the new technologies.

    Huge fan of down! Take care, can wait to hear whats next.

    • Jason Hairston

      Thanks Pedro! More to come at KUIU.


  38. Pedro Ampuero

    One thing that come to mind is that if the down is now waterproof, I guess that you could use a silent outer fabric? 🙂 Typically all down jackets have a noisy finish, I suppose that it was to make it a bit waterproof the outside.

    That would be great!

  39. Andrew

    Jason. Do you know what the differences are between Quix down and other down waterproofers like Dri Down from Sierra Designs? I know Toray makes superior products with most everything they do, but is there one or two things that they stand on that make Quix better? Also, do you know why Sierra Designs only uses 600-650 fill instead of 800-850 like you see in everyones ultralight down pieces?

    • Jason Hairston

      The performance and durability of Toray’s Quix Down is better, significantly better. The down rating spec all comes down to price, 850 is significantly more expensive than 650. Polish Down is more expensive than just sourced down as you should be able to tell in the video. Most 850 rated down is not Polish down unless the manufacture is claiming this. Polish down is second to none but again more expensive.


  40. Andrew

    Thanks Jason. I just didn’t know if there was possibly an application difficulty when applying it to higher quality down since I haven’t seen it on anything over 650 fill yet. Thanks for the info! Can’t wait to see the lineup and hear more details on the bag!

    • Jason Hairston

      No problem Andrew.

  41. Tanner

    Random question, but what kind of watch are you wearing in the quix down video? Love it! Thanks, and can’t wait for new down product to be out!

  42. JP

    Very excited about this product. Any chance we’ll see a sleeping bag manufactured using this down product?

  43. Aaron Tubbs

    I’m pretty sure that this is exactly what folks in places like Wisconsin have been waiting for from you Jason: something to layer up with that will be light and super-warm. I know we’re not necessarily your target market, but the way you’re doing things just clicks with guys like me. Right now I’m using Primaloft Sport products (from a certain company I’m sure you’re familiar with) while in my treestand for Whitetails, but it’s honestly not as warm as I’d hoped. Thought about the Spindrift for one more layer (plus it’s Primaloft One), but now am going to wait to see what you’ve got coming in down! As always, you’re products and business philosophy not only entice, but inspire. Thanks.

  44. Curt Cabrera

    Jason, as you know, I love my Spindrift jacket….but am very much looking forward to these Quix Down products for late season Whitetails!!! I already own an oversized(for me)XL Guide jacket and 36″ Guide pants for layering underneath. This product will take warmth to another level….well done brother!!

    Curt } >>—>

  45. Joseph ewing

    Well the week has passed and we are still anxiously awaiting the ability to pre order. Really want to have this for the rut hunts and late season. I am absoutley in love with your products after living in them for 2 weeks in Alaska and they are working well in the whitetail woods too

  46. Brady Terry

    When putting Quix Down in jacket form will you be making a jacket that has a built in water/wind proof shell or will it just be made as a mid layer piece much like the nano puff by Patagonia?

  47. Jason

    Just wondering on sizing, with all sizing issues being posted.. I want to preorder, but can be a PIA shiiping it back from Canada. I where a xl, room for one layer underneath, in vias guide jacket. Any sizing would be appricated..

  48. James Blakeman

    Hi Jason I am excited about the new down looks like great stuff . I am going on a moose hunt with arct red next fall and was hoping the sleeping bag would be out before my hunt in sept . I am having Steve build me a 300wsm the same as yours and wanted to know if you had any regrets on the conquest scope ? I have been hunting for 35 years and you have the best hunting products I have ever used just wanted to thank you .

  49. Aura night club

    Some fine elements listed here and definitely didn’t have a clue regarding any of this earlier so thanks for your knowledge
