THE VERDICT

Mammut’s shells keep getting better. The Segnas uses Gore’s aerobic inspired Active shell membrane and pairs it with an alpine inspired cut. The result is a bomber jacket that’s ready for speed climbs, hard hikes and any other fast paced adventure. 

FULL REVIEW

Weathershedding
The 3-layer Active membrane is a solid performer. In west coast deluges we never noticed a weakness. Storm proof zips on the pockets and front and a helmet compatible hood help keep the rain where it belongs.

Breathability
The Active shell is one of the most breathable membrane’s we’ve tried. Combined with pit zips—a rarity on Active shell jackets—we were comfortable working hard with a base layer into the high 60s before we started to feel a sweat. That’s one of the biggest ranges we’ve found.

Function
The cut is roomy but also pre-articulated for climbing. Anatomical sleeves stayed put even when we hung off a boulder problem. The hood fits a helmet easily and even when cinched tight still allowed good visibility. The material is a bit crinkly, especially when we ran with the hood on. We missed a chest pocket, but liked that the hand pockets sit out of the way of a harness or pack.

Durability
Unlike most Active shell jackets, which lean towards the minimalist, the Segnas is made for abuse. The face and interior is heavier weight than most and the zips are a bit tougher, which may add some grams but also adds plenty of toughness for demanding situations where a rip or blown zipper could have serious consequences.

Packability
This is a more fully featured shell than most Active shells, so it’s a little heavier and bulkier than the others we’ve tested. But that doesn’t mean it’s either heavy or bulky. It’s still an easy shell to pack around and packs more durability and features than most.
