Rab Kinetic Alpine Stretch Jacket AW26 – Pertex Shield 3L Stretch

🏔️ Description

The Rab Kinetic Alpine Stretch Jacket QWI-73 is a technical waterproof shell designed for freedom of movement in alpine terrain, from ascents and climbing to ski mountaineering. It uses 3-layer Pertex® Shield with four-way stretch, combining waterproof protection with a softer, more flexible, and more breathable feel than a traditional hardshell.

Its approach is especially interesting for activities where mobility and thermal regulation are critical. The articulated construction, underarm vents, and helmet-compatible hood allow you to maintain protection without limiting movement during technical days.

⭐ Mountain Group's opinion

At Mountain Group, we consider the Kinetic Alpine Stretch one of Rab's most distinctive shells. Its strong point is offering real waterproofing with an elasticity and comfort rarely found in a 3-layer jacket.

We would choose it over a stiffer shell when the activity requires wide movements, many hours with the jacket on, and good breathability: ski touring, mountaineering, climbing, or technical ascents. It does not simply seek to protect from the rain; it seeks to allow you to keep moving naturally.
