Pretty thin

Keeps me warm for how thin it is but I had thought it would be thicker. Worried it will rip but haven’t had any issues yet. Definitely like it.

Breast pocket failed

The first time through the wash the breast pocket zipper failed and fell out. It was pretty disappointing to see the poor quality farbric adhesion from a brand known for better quality.

great piece of clothing

This is a thin mid layer. I was skeptical that it wouldn't be warm enough. It turns out to work great in the backcountry. Obviously it's not winter yet but I have another brand of top made from the same material and I like it. I bought this because it has a hood. I find having one in the back country to be really nice. I'm not changing hats when going in and out of the shade and making pit stops. The fit is on the slim side like most Mammut clothing . I'm 6' 180lbs and fit large and wear a large.

Nice thin and light tech layer

This acts as a nice basic wind breaker or sun layer for me. Not overly warm but packs down small and nice to have as a comfy mid layer.

Perfect thin, but warmer mid layer for backcountry skiing. I've also used it frequently running during the colder months and it has worked great. The hood fits under or over a helmet well and is snug for windy ridge line travel. Perfect addition to my ski kit.

I have t-shirts thicker

Individuals who classify this garment as a midlayer may benefit from further education regarding the definition of a midlayer. This particular piece of clothing resembles a t-shirt, constructed from ultra-thin material. When engaging in splitboarding activities, I find this garment useful for shielding myself from UV rays, as it does not provide significant insulation. This garment is ideal for warm, sunny touring days with temperatures exceeding 10-15 degrees Celsius.

Great light layer

Really nice lighter layering. Love the long sleeves. I'm 6'4" 195lbs. the XXL was really baggy.... Ordered an XL and it fits great.

nice for spring skiing, but not as warm as I thought it would be.
