Why We Like The Mammut Taiss Light ML Jacket
Mammut's Taiss Light ML Jacket works for most of our mountain pursuits—from mountaineering and ski touring to climbing and hiking. The mid-weight fleece warms us up in cool-to-cold weather, and it slides under our shell easily, thanks to its athletic cut, smooth nylon finish, and thumb loops that hold our sleeves in place when we're layering. The 4-way stretch and underarm gussets give us great freedom of movement when we're climbing or skiing while the zippered chest pocket is strategically placed above our harness or hipbelt.

This jacket has quickly become one of my favorites. It’s super lightweight but still warm, and it breathes really well when I’m moving. The fit is great (athletic without being tight) and the fabric has just enough stretch so it never feels restrictive. I can wear it on its own on a cool morning or layer it under a shell without feeling bulky. Just a really well-designed piece of kit.

A nice mid layer
A light, stretchable mid layer that can fit over or under most set ups. Very streamlined with only one chest pocket, most likely done to keep weight down and as backpack hip straps would have blocked access to other pockets. Versatile and suited for high aerobic exercise.

Perfect layer for alpine style mountaineering here in the PNW.

Great product but poor stitching
Fits well for technical endeavors but the flatlock seam stitching on the wrist is unraveling on the second wear The color and fit are great as is the function and design. It breathes very well and the thumb loops are excellent but the stitching is poor. I can’t recommend due to this. I am going to have to warranty or try to sew it myself which is unacceptable after only wearing twice.

Great but why itchy tags everywhere?!?
Love the jacket, but don't love Mammut's recent change from printed tags to sewing rough, itchy tags in the neck line that are impossible to separate out without damaging the stitching of the jacket. Same is true for several t-shirts I bought. At least put the tags on the waist line of the jacket/shirt and not the neck!

I really like it. wear it a lot on temperate days or when I think I may need one because it packs small into a bag. I just wish it had hands pockets

The jacket runs small, has no pockets and there are no returns. Do not recommend
