"What Our Gearhead® Experts Are Saying: ""I’ve used the Taiss HS Hooded Jacket for ski tours and summer alpine climbs—it’s light, packs well, and still gives bomber weather protection. The single-pull hood adjustment is clutch with gloves on, and the breathability keeps me from overheating even on big pushes uphill."" When we’re moving fast in the mountains, protection and mobility are non-negotiable. The Mammut Taiss HS Hooded Jacket brings year-round versatility with a lightweight, fully waterproof 3-layer design that balances toughness with breathability. With a 27,000mm water column and 48,000 g/m²/24h breathability, it shields us from storm conditions while keeping us comfortable on the move. Technical features make it a climber’s and mountaineer’s ally. The storm-proof, helmet-compatible hood adjusts with a single pull, while generous harness-friendly pockets keep essentials within reach. X-vent underarm zips dump heat quickly, and pre-shaped sleeves plus elastic materials let us climb and skin without restriction. Finished with a PFC-free DWR and weighing just 435 grams, this hardshell is a lightweight yet rugged layer we can trust in all seasons."
