Awesome sweater

Comfortable, warm, breathable, and sharp looking too. I've tried a lot of nice fleece and wool pieces. This is one of the very best.

Too long

Great jacket but the sleeves and general length is oddly too long.

style over substance

Comfortable and stylish (till the logo started peeling off a bit at a time). Unfortunately, mine had a defect in the seam on arrival and the logo came off within a few months, also had some pilling. Functionally similar to R1 or other light fleece.

This is my go-to midlayer for ski touring. Using this with a baselayer has been a game changer for staying comfortable while ski touring -- it's just warm enough, and breathable.

Awesome Layer

Light well-made layer! Great company too. I am never disappointed with MAMMUT! This runs large just so you know but it is really nice to have a Lightweight fleece for any time of year. I use this around the house, skiing, and while playing disc golf. Love this piece, I wish they had more color options but black goes with everything so it works. I took this to Europe and was super stylish on both sides of the pond! Cheers!

Warmth,fit, stretch, breathability! This jacket has it all. Perfect as a midlayer for warmth and as an outer layer for high exertion activities.

Awesome

So far used this for an autumn evening out, walk along the beach at sunset, and a chilly evening mountain bike ride...looks and feels great!

Feels decent, but no pockets

I've enjoyed this light jacket, it is a little loose fitting and is a little on the lightweight side. I will most likely wear this more as a mid layer. Oh yeah, and there's no pockets of your hands or anything else, just the one chest pocket, took me off guard.

Fits true to size. Not too tight like a baselayer, but snug enough to feel comfortable. There aren't any hand pockets, but the chest pocket is a nice piece. Material is very comfortable! Definitely thin enough like a track jacket, but is warm enough to be comfortable at mid 50F temperatures with a t-shirt underneath. The style is really nice as I always get compliments whenever I wear this.
