Mammut’s lightweight shell has some unusual design features. The super stretchy Gore Windstopper shrugs off wind and light rain well, and all the drawstrings are inside the jacket which means there’s not much to snag or pull by accident. I prefer not to bother with thumbloops on a technical jacket, but others love them and they are discretely designed in this offering. The hood is (just about) helmet compatible but could use a rear drawcord, but the 3 torso pockets are high enough not to interfere with a pack or a harness. Zips are all 2 way, and it packs down small and is lightweight at around 500gms. The jacket is a regular fit in the body, although the length is on the short side so those with longer torsos might want to try before buying. The most unusual aspect of this is the elbow to hem pit zips, which means it’s amazing for dumping excess heat but can feel a bit fussy under a pack. There’s very little insulation and as such it’s proved great for high aerobic activity (running especially), but might not offer enough protection for those who feel the cold.
