Warm, functional, and lightweight, the Taiss Pro IN Hooded Jacket is a dependable companion for demanding mountain pursuits.
Mammut says:
Designed for 4000-meter peaks, ready for use in all freezing altitudes and harsh mountain conditions. The weatherproof down jacket delivers ultimate Mammut cold protection in its featherweight, compressible form. This is made possible thanks to the durable recycled nylon exterior with its 850 cuin fill power derived from responsibly sourced hydrophobic down that insulates even in wet conditions. The backpack- and harness-compatible pockets can be used for your essentials when you're touring or belaying, and you can even stow the jacket inside itself if you need a warmth backup.
Our Verdict
The Mammut Taiss Pro IN Hooded Jacket is a robust and lightweight down jacket designed for alpine adventures. It offers exceptional warmth, packability, and weather resistance in extreme conditions.
Filled with 850-fill power hydrophobic DRYDown, the jacket provides impressive insulation even in damp environments, making it ideal for harsh mountain climates. Its durable and weather-resistant Pertex Quantum Pro outer fabric, crafted from recycled nylon, is also durable and weather-resistant. At 479g (size M), it balances warmth and portability, stowing conveniently into one of its pockets for efficient packing.
The thoughtful design includes a helmet-compatible hood with single-point adjustment, a two-way front zip for harness accessibility, and multiple pockets for storing essentials, including two internal Powermesh pockets for gloves or snacks. Pre-shaped cuffs and an adjustable hem further enhance fit and functionality, allowing complete freedom of movement during technical climbs or belaying.
While the jacket’s warmth is excellent for alpine use, it may feel excessive during high-intensity activities in milder conditions. For prolonged exposure to wet weather, pairing it with a protective outer layer is recommended.
