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

🏔️ Description

The Rab Kinetic Alpine Stretch Jacket QWI-73 is a technical waterproof shell created to move freely 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 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 for maintained protection without limiting movement during technical days.

⭐ Mountain Group's take

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

We would choose it over a stiffer shell when the activity requires wide ranges of motion, many hours wearing the jacket, and good breathability: ski touring, mountaineering, climbing, or technical ascents. It doesn't just aim to protect from the rain; it aims to let you keep moving naturally.

⚡ Real technical performance

The Kinetic Alpine Stretch uses 3L Pertex® Shield with four-way stretch. Rab specifies a hydrostatic head of 15,000 mm and an MVTR breathability of 20,000 g/m²/24 h.
