CoEfficient Hoody is rated out of 5 by 9.
Rated 5 out of 5 by Crusty from Essential Piece for every Patroller! This piece has served me well in my first year with the NSP - ideal mid layer when your day is a constant stop and go. Comfortable over a wide temperature range - full zip front makes it easy to dump heat fast. The cut of the hood works well with a helmet. Cuff design is simple - everything you need, and nothing more. Snug fit keeps the snow out. Yes - it only has one pocket - it's a mid layer! I've got a jacket and pack to carry essentials. For reference, I am 5'11", 172 lbs, and I went with the large. After a month of using this nearly every shift, I purchased the jacket version to wear for nordic skiing, when I don't need/want a hood.

Rated 5 out of 5 by Jonathon from A Real Mid-layer for the mountains. This layer if finally a mid-layer that won't cause you to over heat. For years i've been looking for a lightweight mid-layer for climbing, ski touring, and alpine climbing. For years I used an R1 layer but was always to hot in it and just found it way to warm when i was moving in the mountains. The CoEfficient layer is lighter and more breathable then an R1. The hoody is a good fit and works well with helmets both (ski and climbing) For sizing help: I got a Large and i'm 6ft and about 165lbs. Overall really like this layer and hope they make it in some different colors for next year.

Rated 4 out of 5 by Kevin from Excellent mid layer hoody This is an excellent hoody to use as a mid layer when hiking. The inside is super soft. The arms are plenty long. I'm very tall and it's hard to find a good form-fitting hoody like this, but it fits me very well. The chest pocket is great. I have 2 gripes about it which made me only give it 4 stars. There are no hand pockets. I know it would add bulk but for me I would really love hand pockets on it. Also, the hood doesn't fully come over my head. Maybe they were thinking about people wearing helmets or something, I'm not sure, but it's not a big enough hood for me and my head isn't that big. Overall I really love it and use it all the time. I would highly recommend it.

Rated 5 out of 5 by Rock Gypsy from Thin and Long...Great for use with a harness. I bought this jacket about a month ago, and so far I really like it. It is very thin, so first realize that you are buying a tighter fitting thin jacket that covers down to your hips. I love how stretchy it is. It works great for me because I'm a rock climber and iy fits great under my harness. The length insures that it stays under my harness even when I have to do long reaches. Also thin enough to fit perfect under a windstop layer. It's been a chilly winter in Red Rocks this year, and this jacket works perfect for me when I have to layer up. I usually hate wearing a jacket while rock climbing, but after a few minutes I hardly even feel like I'm wearing a jacket at all because it is so stretchy and thin. It's so comfortable that I have practically been living in this thing. I even wear it at home instead of going for that old flannel shirt. Another reviewer said that they would like to see this hoody with hand pockets. I think that his one is fine without pockets. If you really have to have pockets then check out the "Solution Hoody" it is very similar to this jacket. Same great layering ability and fit, but has hand pockets. I have both jackets, and I love them both equally.

Rated 5 out of 5 by Chris from Excellent Fleece I've used this one for backpacking, climbing and skiing. It packs down well, it's warm, the Napoleon pocket is a nice touch, but even nicer are the thumb loops, perfect for skiing and pulling gloves over, and functional if you're not quite ready to put gloves on for the cold backcountry evening. Hood works great too, fits well under a ski or climbing helmet. Great fit.

Rated 5 out of 5 by owen from Can't speak highly enough of this piece The coefficient hoody is AWESOME! + The hood is perfect under helmets + Length tucks in securely + Soft cuffs are awesime + chest pocket is the perfect size (I've altered mine to hold my radio) - BD colors all suck now... alas... I have three generations of these, won't be getting a new one this year.

Rated 5 out of 5 by Crit from Great alternative to the R1 Talk to anyone that has an R1 hoody and they love it. Bd has nailed it with this response to that garment. I actually go for this a bit better cause the neck is more comfortable (My R1 does that dumb zip up the side of your face thing) and it's full zip. I do miss having thumb loops, but I'm ok without them. My only real complaint is that after a while of use it does the silly thing that all waffle-type garments do and it develops those little pills of fabric that poke out on the outside and for that reason I don't ever put it in the dryer (don't know if that helps, but it puts my mind at ease). This just makes it look a little less presentable for around town, but I usually keep it as an active piece. Either way I love it and you definitely want one! i'm 5'9" and 140lbs and a medium is perfect. oh also, it's a big longer in the waist (still slim fitting) than you might think. great for wearing under a harness or backpack, but it does give you the little waist pooch pretty severely.

Rated 5 out of 5 by Jonathan from Great simple mid layer No fills just function. Light-weight and compressible, this hoody has been my best friend this past season. I wear it in between burns at the crag, while I'm climbing in the morning, and around town.
