The Arc'teryx Naya Cropped Stowhood is built for those unpredictable shoulder-season days when the forecast says maybe wind and the trail demands you actually be prepared, delivering lightweight, durable shelter that zips away into its own collar when the sun decides to cooperate. The breathable fabric dumps excess heat if you're working hard and climbing steep, the cropped, relaxed fit keeps this layer packable enough to live in your pack without taking up space, and the hood cinches tight when conditions turn sketchy.
