Mammut  Taiss IN Hooded Down Jacket - Men's

I ordered this jacket to bring with me on an outdoor climbing trip to Red River Gorge in KY. The last time I went ,it got very cold and I was miserable while belaying because I couldn't keep my jacket zipped up without blocking the belay device from going on my harness. I got this jacket because it has a second zipper at the bottom that I can unzip the jacket from the bottom up to fit a harness and belay device through while still being zipped up top. The jacket also claimed to be very warm. All expectations I had for this jacket were instantly met. It worked perfectly while belaying, and I was warm and cozy while only wearing the jacket and my base layer in low 30s weather.

This jacket came in a lot less puffy then i was expecting. It is a bit tight in the shoulders and upper arms if you are more of an athletic build. It is extremely light and packable for the warmth it provides but is only a base layer for cold weather campers. I would recommend sizing up if you get this jacket. The higher side pockets are nice for wearing a pack but not as great for everyday use in putting hands in pockets.

Highly packable, ultralight, very nice. I brought this on a through-run of the Enchantments in Washington. It was so light I didn't notice the weight. It's very warm, fits well, and looks good. Can't speak to durability yet. This is great for backpacking, ski touring, climbing, or other sports where light weight is a premium. You would want to bring a hard shell to wear on top of this if you were expecting rain or wet snow. I would not recommend this jacket for wearing around town because it has very thin outer fabric that could be damaged easily, but in a pinch it's stylish enough to feel at home around town too. Note that the zipper is "backwards": women's/Euro standard where the zipper pull is on the left side. I'm used to it and it's not a drawback, just different. Enjoy the tiny bit of mental challenge it might provide. ;) I bought size medium which was the right size. I'm 6'1, 168 lbs, slim athletic build, 38" ish chest.

Definitely one of the warmest jackets I have owned. even with just a t-shirt underneath, it kept me warn in 5 degrees (Fahrenheit) with a decent wind. Super light weight, and stuffs small so easily tucked away when you go indoors. Great for just a jacket to run errands in, or sledding/skiing, or even winter camping

A very light and lofty jacket. A little difficult to stuff in a stuff sack but I think that is because the seams are so tightly woven making it hard for air to move between the fabric, which is a good thing when it comes to wind. Though not lined with fleece, the hand pockets feel very soft on the hands and are warm! The hood works well with or without a helmet and provides good chin/mouth coverage. The only annoyance is the waist drawcord can become long and hang out of the bottom of the jacket when tightened. I mainly use it as a multi-pitch belay jacket and an emergency jacket for long trail runs. Its lightness has been very appreciated in those scenarios. A chest pocket has not been necessary since usually at least one of my base layers will have one. Warmth-wise: I ran to a summit at night where the windchill was around 0-5 degrees f and it kept me comfortable. Underneath I had a warm base layer and an alpha vest. Other times I've had to wear it where my core temp wasn't so high have been at 30 degrees and I felt comfortably warm.

I took this on a trip into the mountains during a cold snap of -30s F and it kept my core warm when paired with a wind shell Slight annoyance is the lack of a breast pocket for a phone or other things you want to keep warm

loved this jacket. so lightweight and warm. perfect fort everyday use and also an amazing layer for cold days touring or ice climbing.

The coat is very warm for its weight. However, it would be nice to have a bit more fill. Strong winds can still penetrate this coat.

Perfect for anchorage winters. Solid mobility light weight and waaaarm

The jacket is very light, and yet provides great warms
