Eclipse Cap

‘This hat turns a neat trick: Top-mounted vents can be flipped open on exceptionally hot days or left closed if you want full protection from the sun. The curved lines on the side make it comfortable on long runs, and it doesn’t interfere with sunglasses. The foldable bill dials up usefulness, so you can pack it flat in your gym bag’or tuck it in the waistband of your shorts, if you need to ditch it mid-run.’
