Sitka Hyperdown jacket and pant review

[Tony Trietch]

Sitka has a new down puffy top and bottom and I will be writing up a review on them after using them this season. Let me know what you want covered or answered and I will try to include it in the review.

Sitka HyperDown Jacket and Pant - Rokslide

This last summer, Sitka released the Sitka HyperDown jacket and pant along with the new HyperDown Sleeping bag. You can read Josh Boyd’s review of the sleeping bag here. Hyperdown Jacket and Pant The HyperDown jacket is Sitka’s warmest puffy jacket and, in my mind, replaces the Kelvin WS Hoody...

Hey Tony can you get Sitka to comment on the fill they used? And why it’s different from the sleeping bag, which actually advertises the “hyperdry” allied feather product? Just curious behind the story of “why” with the product. It looks awesome, been waiting for the Sitka mega puffy. Also - can you get a fill weight out of them, they only list fill power.

I will ask them why they are different. I was wondering that myself.

Any idea why they didn’t/haven’t release them on their website? Would like specific details and the story.

 

[Tony Trietch]

I posted the links at the top, they are on the website.

I contacted their CS and they said 230 grams so roughly 8 oz of fill.

Does anyone else find it really odd that they still haven’t done an official launch? No email, no official Sitka video.

They told me that they were waiting until later this fall to push these. I was surprised myself.

What advantage does this jacket have over the Kelvin Lite Down jacket?

This has far more fill inside, so stationary warmth. About double the fill weight.

MT_Wyatt nailed it, this is Sitka's warmest puffy they are currently making.

How’s sizing compared to other pieces? I’m between a medium and large in most sitka

 

[Primal-Understanding]

Id like to compare this to the new First Lite White Cloud.

I would like to hear your thoughts on the sizing and noise.

Thanks!

I asked Steven Drake the same thing in case he knew someone that knew "why" - he just posted about this piece talking about the "gold flakes" (ie the allied down product). What's confusing is Allied does have a hyperDry fill, but ExpeDry (https://alliedfeather.com/info-room/products-innovations/expedry) is the Allied product used in the HyperDown sleeping bag.....but not the HyperDown Jacket. He's probably got a test piece that does have that fill, but why not send it to market with that (cost likely)?

"a technology called FUZE to create tiny gold particles that permanently bond to the down inside the insulation chamber, creating an electrostatic barrier that stops, say, humidity from condensing into water."

I know that doesn't actually answer the quetsion, but I thought it was funny one of their main sponsored folks was talking about the jacket and having a different fill than is actually advertised.

I would say it is a bit bigger than past puffys.

I will see if I can get my hands on that piece.

It is not very quiet, but it's not intended to be. I would say it is a bit oversized to easily be worn over your other layers.

Gold flakes in our insulation....crazy to think what technology has done to clothing. I think Steven is an employee or at least subtractor for Sitka, maybe they are being quiet about it for a reason?

They are OVERSIZED. I’m usually an XXL or XL and the large was big enough for me. Anyone notice the amount of patches Steven had on his puffy ? Sticking with Kuiu puffy.

 

[Brewski]

I got the size medium pants with the F&F discount. Size medium pants weighs 1lb 2.5 ounces. The medium size is big and long and are more like a large. The pants are around 3x noisier than the uncompahgre puffy pants. The outside fabric is thicker and rougher than the uncompahgre fabric. Overall good build quality. I haven't had cold enough temps to test but wearing around the house I would guess 3x warmer than the uncompahgre.

@Tony Trietch did you ever get an answer on Sitka on this Hyperdown fill being the high end product in the sleep bag, and the primaloft down gold blend in the jacket/pants? If not I'll ask them to comment. When I stopped into their place in Bozeman the sales folks had no clue. Even weirder, they used 900 FP version in their Lite Down line that was discontinued, but using 800FP on this piece. I assume it is to keep prices down and not be at that Super Down Burner parka cost level.

Drake again with a vid today talking about the Hyperdown Jacket/Pant and having the same insulation - tough look when the influencers can't get it straight (in his defense, I'm sure his prototype actually had that fill).

 

[Kostrize]

For comparison sake Katabatic Gear is now also using 900 fp ExpeDry in their quilts, ostensibly the same as what Sitka is using in their sleeping bag. Not the same as the blend used in Sitka’s jacket and pants but if anything the cost difference should be greater

I don’t think Katabatic’s prices are that much higher with ExpeDry than when they used Hyperdry in their lineup. If at all
