The OR Radar cap is the final addition to your wardrobe. It's lightweight, super comfortable, breathable, and I LOVE the folding bill that's perfect for stuffing in your back pocket, pack, or wherever you need to stash it. I get tons of compliments on it when I wear it. It's been on backpacking trips, hikes, climbs, etc. and stands up to it all. However it is NOT adjustable and there is no elastic in the band so the size actually matters.
