Recent Synthetic Insulated Jacket Reviews
Outdoor Research Shadow Insulated Hoodie
The Shadow Insulated Hoodie is a mid-weight insulating layer; a relatively thin layer of synthetic insulation is sewn between two layers of somewhat wind-resistant but air-permeable and somewhat stretchy or forgiving shell material. The Shadow Insulated Hoodie is appropriate for a fairly wide range of temperature and weather conditions as an outer layer or mid-layer. This layer’s best use is for high-output cool and cold weather activities where you want to stay warm while working hard and generating… Full review
Rab Xenon 2.0 Insulated Jacket
I’m now on my second Rab Xenon jacket. I wore the first one nearly every day from fall through spring for years until the outer fabric finally started to wear through. My first Xenon jacket only had a one-way main zipper so it didn’t work well as a chilly-weather belay piece. That’s the only thing I had wished Rab had done differently. By the time I bought my new (second) Xenon jacket Rab was making them with a two-way zipper. Yay! On the downside, the first Xenon fit perfectly, but the… Full review
Rab Alpha Flash Jacket
Breatheable, lightweight midlayer that pairs perfectly with a wind shirt. If you want to go light, this packs warmth like few other midlayers... but there are caveats. The Rab Alpha Flash is an outstanding midlayer for active use. Constructed almost entirely of Powertec Alpha Direct, it breathes so well that you can leave it on during high-exertion activity without overheating. Plus, it dries fantastically, freakishly quickly. It is not a general-purpose garment, but it absolutely excels when worn… Full review
Arc'teryx Atom LT Hoody
Amazing jacket which regulates temperature and moisture, great fit and comfy hood; have used it in winter high-exertion sessions with a T-shirt underneath, and bad weather with a hard-shell over it. Greatly recommended for all winter outings with a harshell in the backpack, or shoulder season. I came into some additional money and was browsing my favorite website to treat myself, and found a great deal on this jacket; price paid 140$ (in late summer for those interested). The jacket is soft and… Full review
Outdoor Vitals Ventus Active Hoodie
The Outdoor Vitals Ventus Active Hoodie is a phenomenal mid-layer jacket that’s built to move with your body. Not only does it provide warmth when it counts, it’s also somewhat breathable and resistant to moisture. If you’ve ever been running in a chilly environment, you know how difficult it can be to get the right layering system down. Many jackets or sweatshirts are too bulky, not breathable, and prone to suffocate you. But Outdoor Vitals’ new Ventus Active Hoodie provides the perfect… Full review
Buffalo Mountain Shirt
Incredibly functional, warm, and featherlight protection for high effort activity in wet, windy, or cold climates. Buffalo Mountain Shirt After suffering the last 30 years hiking the PNW in a 3l hard shell, being too hot walking uphill, and shivering all the way down because I was soaking wet inside from sweat, I decided I'd had enough. Did some internetting and found out about Buffalo. The Mountain Shirt fits comfortably loose. The Special 6 is the same, just longer and therfore better for the… Full review
Buffalo Mountain Shirt
Special gear that needs an Active/Static rating table for reference. Great garment to keep you safe in the wilderness, I would say 0°F to 40°F depending on activity. Especially good and safe in the 25°F to 35°F range. Comfortable to wear in static conditions above 40°F. Full review
Buffalo Mountain Shirt
The most versatile outdoor garment I've ever used. Possibly the best return, for the initial purchase price, of any athletic kit I've bought. I've had at least one Mountain Shirt in my kit bag, since 1990. A great three-season climbing, hiking, paddling, and cycling layer, designed to fit close, wick away moisture from the skin and as a barrier to wind chill. I sometimes use a thin polypropylene under vest and would want a waterproof extra layer for heavy, prolonged rain, extended rest stops, or… Full review
Mountain Hardwear Kor Strata Hoody
A well-built, breathable insulated jacket that competes with more expensive models. I was looking around for an insulated jacket that wasn't going to break the bank and not so techy-looking that I couldn't wear it as a day-to-day jacket. The MH Kor Strata Hoody definitely checked the boxes and it's become my go-to both on the trail and around town. Like most every day. Big bang for the buck with this one. It uses PrimaLoft Gold Active and while it definitely cuts the chill just standing around I… Full review
