Royal Robbins, A smart windbreaker that never stops working, this lightweight shell protects you from the weather, then – when the sun shines – converts to small cross-body sling bag. Highly wind and water-resistant, this incredibly stretchy jacket is a perfect layering piece. The material is treated with eco-conscious C0-DWR to shed light rain. A clever strap lets you sling it over your shoulder, and the bag has a pocket for your wallet or map.
