Why We Made This

We wanted to redefine how a softshell vest performs on active outdoor pursuits. Our solution was to create a jacket that breathes well, blocks wind, repels light rain and snow, and doesn’t inhibit movement. We achieved this using GORE® WINDSTOPPER® for unbeatable wind protection, a DWR finish to prevent the face fabric from wetting out and articulated patterning for a complete range of motion.

If it says Jetstream it’s 5 star!
23 years as a Game Warden and I’ve never found a jacket/vest that for the weight is as warm as the Jetstream. From the water to the woods it keeps you going while having the best wind cutting performance of any outdoor brand I’ve tried….and I’ve tried them all. I don’t hunt, fish or work without my Jetstream packed or close at hand. I would love to see the two double front pockets and sleeve pocket return. You can never have enough pockets! Keep doing what you’re doing Sitka and I’ll keep you in business!

I have had a few of these Jetstream vests. I really like this fit. More freedom in shoulders and arm holes. I despise vests that crawl up in armpits, especially while reaching forward. This one does not do this. Material good weight for what the vest is meant for. I use this almost daily. Nice job. ??

Waited a couple of months for the dirt vest in my size to get is stock. I have it in subalpine and love it. I wear it pretty much everyday. Fits great , looks great and is very warm for the light weight.

I have used the Jetstream vest as part of my hunting ensemble for more than 6 years and won’t leave home without it.
I wanted to at the Jetstream vest in the solid colours for everyday wear because I love it so much!
It’s a sharp cut low profile warm and wind proof vest that can be used as a stand alone piece or layered with anything!
However my favourite is layered with the Kelvin jacket for a light weight incredibly warm and comfortable package that can be packed into your backpack with very little space and added and subtracted as the weather dictates.
This vest will keep you comfortable warm and dry on those cool mornings and can be quickly layered for extra warmth if needed.
I now have 5 vest in different colours if that speaks to how much I enjoy this product!

This vest is great for exactly what it says, stopping the wind from sucking the heat right out of you.I ordered this vest thinking it would be thicker and I would be using it for a layer of insulation under my Fanatic jacket on them really cold days.. When received I could tell it's thinner then I imagined but I knew I could still have a use for it.. Now I use it to go over my hoody while I walk to the stand. I don't were my coat or bibs walking I always put then on at tree.. And I also plan on using it for earlier in the season as a way of really keeping the wind off my core and being able to wear lighter clothing .If your looking for more of an insulation layer vest this isn't it.. But if your looking for something clean, cut right , fit right , to go over your base layers or a thick hoody to retain core temp..This is deff it.. It's perfect for exactly what they said..keeping the wind out. I don't regret this purchase and I think it is going to be a huge part of my system that I didn't even realize I was missing .. I were an XL in sitka and the vest was XL and fits just like everything else .

Solid vest, does its job as a layering piece. Fine to wear as an outer layer in mild breezy conditions. Love the flexibility of the arm holes. Makes it easy if you need to take off quickly.

Enjoy the color material, but the vest is too small. I have always used a small on other purchases but this vest is tight.

I purchased this gift for my husband as a Christmas gift! He loves it! We ordered his normal size XL (he’s 6’2”, 220 lbs for reference). He said it’s sleek and comfy, not too thick like most vests! After seeing how happy he was I ordered the Laurel Vest (women’s) for myself. I’m excited to receive it!

I've been wearing a JS vest for 8 years and loved it so much I order the 2022 version in solid for everyday use - BIG disappointment. The new material and construction is fantastic but the other changes are not improvements. Sizing: The new "standard fit" is too baggy in the torso even with the draw-string hem. The shoulders lost the elastic cuffs and now are large, gaping holes for arms - and cold air. Details: The large hand-warmer pockets are gone and replaced with thinner, smaller laminated versions. The storm-flap behind the zipper is now a stiff tape-like material that is uncomfortable against the neck. Before updating products, Sitka needs to understand the features that users like and design from there. The JS was unique - now it's just another shell. Also, the color Granite is a very light gray - it is OK but just not dark like the photos. I returned mine and am looking for an older version.

I purchased this vest to upgrade my state mandated orange vest for rifle season and I couldn’t be happier. This vest cut the wind very well and provides an extra weather resistant shell for those less than ideal conditions. Ordered an XL to fit over my jacket (5’09” / 210lbs) and it works great!

I ordered the Jetstream vest in 2021 and was really looking forward to adding this garment to my collection of Sitka gear. Unfortunately, I was not happy with the fit fine around the chest and waistline, but it was too constraining in the shoulders. I'm an archery hunter, so that was a major concern and the vest was sadly returned.

Fast forward to 2022....I stopped by the Sitka store in Bozeman and mentioned my concern with the Jetstream vest. The sales representative smiled and asked me to check out the "new" Jetstream vest. Wow, it fit perfect and the new cut alleviated the problem I had with the fit in the shoulder area. Same size as before (Men's Large), but a much better fit. If you've tried this vest in the past and had concerns with the fit, I suggest giving the new model a try.

Great fit and perfect warmth as a mid/base layer and I was able to move quickly without restrictions. Only flaw is zippers strings wanted to come loose but were easy to tighten back up.

I love wearing a vest, and this is the best on the market - and the best SITKA has ever made. The fit is tremendous, and aesthetically it’s nice enough to be worn outside the field. It provides just the right amount of additional warmth and wind protection you need to finish out a variety of waterfowl systems. If I wasn’t wearing it, the Jetstream vest was almost always rolled up in my bag ready to go if the conditions took a turn.
