Sunday Afternoon Sun Tripper CapPlus, there are three features we love: integrated sleeves that hold sunglasses in place, a hidden interior pocket and an adjuster to fine tune your fit. This is the Swiss army knife of sun hats. HGTV The Sun Tripper Cap loves the meandering backcountry trail just as much as it loves after work happy hour with friends. The innovative Clamshell Brim folds down to almost nothing so youll have reliable sun protection no matter where your day takes you.
