The Craft Rain Hat is a classic cycling cap with a couple of high-tech twists. It is both wind and waterproof with taped seams but the best thing about this cap is how it stows. Craft employs a hinged brim that allows the cap to fold very flat so it takes very little space - it even comes with its own storage pouch.
The hinged brim also keeps the hat looking great where a traditional brim might become trashed. It is almost a secret weapon against the rain but will also insulate from the wind and cold. Made for cycling but could also be used for any outdoor activity.
