Rab's 600-fill hydrophobic down keeps insulating even when it's damp out, so Southern humidity and wet weather don't kill your warmth. The streamlined cut and helmet-compatible hood layer cleanly under a shell without bulk.

• Lightweight shell fabric resists wind and light moisture without adding unnecessary weight to your kit
• Fitted hood works with a helmet or layers cleanly under a hardshell — no bunching, no bulk
• Built for cold-weather hiking, backcountry hunting, and alpine climbing where conditions can change fast
