Ultimate VIII SO Hooded Jacket offers breathable windproof protection and alpine-ready features
What Our Gearhead® Experts Are Saying:
"This is my go-to shell for alpine layering in high-output conditions. It blocks wind like a fortress but breathes better than most softshells I've worn. Great stretch, smart pocket layout, and the hood fits over my helmet perfectly."
From high-alpine ridgelines to wind-swept summit pushes, the Ultimate VIII SO Hooded Jacket gives us a serious edge against the elements. Mammut equipped this piece with GORE-TEX WINDSTOPPER® fabric backed by a breathable 3D moisture-wicking structure—delivering storm-worthy protection and ventilation in one alpine-tuned package.
The softshell-style fit moves with us over rocks or on rope, while technical details—like the helmet-compatible hood, reinforced peak, and thumb loops—support comfort and utility on big objectives. With multiple zippered pockets, underarm venting, and a two-way front zipper, this jacket balances toughness with thoughtful performance for the fast-moving mountain athlete.
