Product Insights & Style Tips
The Mammut Taiss IN Hooded Jacket channels serious alpine energy into a featherweight silhouette. With 850-fill DRYDown for extraordinary warmth-to-weight and loft that stays resilient in damp conditions, it feels almost invisible on the move. The recycled nylon shell with a weather-resistant coating repels wind and light moisture, while synthetic insulation in high-wear zones—shoulders, forearms, and hood—adds targeted warmth where it matters most. A helmet-compatible, adjustable hood completes the setup for fast approaches and high-altitude moves.
Regular in length, it sits at the hip and layers easily under a shell or over a midlayer. Pre-shaped sleeves follow the shoulder line for easy mobility on climbs and belays, while a two-way zipper lets you vent when you heat up or zone in on technical sections. The stowable design means this jacket packs down neatly when the weather shifts, and the hydrophobic down helps maintain loft as you move between wind pockets and brief showers. It’s built to move with you, not hold you back, through every transition from trail to ascent.
Taiss sits at the intersection of rugged alpine craft and modern packing efficiency, a Mammut staple for serious outdoor pursuits. It nods to the trend toward ultralight warmth that doesn’t skip durability, pairing a streamlined silhouette with durable reinforcement in the places you carry the most weight. Style-wise, its functional, low-profile look pairs with shell pants and a fleece midlayer, ready to stand up to the demands of high country while keeping the outdoorsy spirit intact.
