I was hoping this would be a good layer for touring and light precip days. Unfortunately the sizing is really on the smaller size and the fit is awkward. I'm a very average 5'11, 165lbs and the sleeves, pockets, hood, and especially torso length are all out of proportion. If the fit works for you it could be a pretty decent layer, but it did not work out for me.

New Go-To Jacket

This jacket is a perfect jacket as a stand-alone jacket on those breezier days and offers surprisingly good warmth as an inner layer for how light it is. The quality of materials is second to none and I find myself grabbing it as my go-to jacket to pack on hikes as well as for skiing and outdoor camping activities. I highly recommend this jacket. For sizing, I'm 6' and am 180 pounds. Strictly based off of the recommendations on the Mammut site, I should get a medium based off of my measurements. However, I found that a large fits me better with more room in the chest and in the arms. The medium was a much tighter fit around the chest and waist, so I went with the large and I couldn't be happier.

Great light jacket that keeps warm well but still thin. Very comfortable too.

Almost 5

Liked everything about the jacket. Glad I ordered a L. The main zipper is finicky but apart from that, it's a great product.

Great Base Layer Jacket

Awesome jacket that has some stretch to it and warmth. One thing I would recommend is to get a size up. Fits narrow to the actual measurements.

Great soft shell

Jacket holds heat even when wet with sweat. Does a great job at regulating temperature. Hood is nice and tight to the head for wearing under a climbing helmet. Jacket is very light weight. Love the thumb loops, very comfortable. Size runs slightly small if you ask me....but it fits like a glove. Only downside is it holds smell pretty bad if you're sweating in it a lot unlike wool but just wish it and it's ready for the next trip.

Good design and features but delicate

I've used it several times
Size Bought:
6' 1"

I purchased this to use as a soft shell when ski touring and as an under layer for my ski jacket. In terms of fit, pockets, and warmth with wicking, it’s good. One note on fit is that it seems a bit on the short side but I have a long torso. My only critique, and it’s an unproven concern after only a few uses, is that the material used to make the jacket is really thin and seems unlikely to stand up to extended wear with pack and gear constantly rubbing against it. The zippers are not heavy duty either. If I had felt this fabric and zippers in a retail store I probably wouldn’t have purchased it. Given Mammut’s reputation for quality, I decided to keep it anyway.

Ski touring uphill layer

I've used it several times
Size Bought:
6' 1"

I bought this as my uphill outer layer. Overall the weight and fit are good. The materials are good and the light shell seems to shed moisture and breath. It’s overall a little short ( I’m 6’1”). Also it needs an inner or outer chest pocket. This replaced my Selewa Jacket which had a Skins pocket on the inside and an outer chest pocket- ideal for phone away from beacon. With an inner skins pocket and chest pocket would give a 5 star

Versatile and Valuable!

This is a good soft outer layer on dryish days, it will work in a shower but you need a hard shell for very wet days. Insulation is great and is stops the wind dead in its tracks. Two deep pockets are good, a chest pocket would be nice. The collar zips are nice and high and the hood fits well but some toggles to pull it down would be useful. I'm 6'1 175lb and it's pretty snug with a size Large, if you prefer a looser fit size up. It's almost a bit too short in the body as when I wear it my mid layers poke out the bottom. The sleeves are fine lengthwise and have an interesting thumb loop made from splitting the cuff. Finally, it packs down into its pocket which is a nice feature so you'll never loose the stuff sack.
