🏔️ Description
Rab Downpour Mountain Pants. Waterproof pants to complete your protection against rain and wind during mountain routes. Their 2.5-layer Pertex® Shield 40D construction allows you to carry a specific protective layer for when the weather turns.
⭐ Mountain Group's Review
Consider the type of side opening and the space for the layers you will wear underneath. Protection that you can put on and adjust easily is more useful than choosing solely based on the name of the membrane.
