Stay protected from the sun's glare with a cool pair of polarized shades, some sunscreen, and a running cap. We love Oakley's Beckon sunglasses ($160) because they are as fashionable as they are functional! Keep the face protected with lululemon's wicking cap ($32), which has a nifty zip pocket on the side, and don't forget to slather on some Neutrogena Sport Face suncreen ($12). Regardless of the season, staying hydrated is key; we love the Water Geeks Lab bottle ($24) because of its built-in filter that gets rid of impurities. Unpredictable Spring weather means layering, but you can skip the jacket with these Sugoi Lucky Arm Warmers ($40). Stretch them up to stay warm while riding, running, or hiking, or push them down to feel the sun on your guns.
