Versatility is important when trying to pack light for a shoreside excursion, and Airgill convertible pants ($80, shown) and Backcountry long-sleeve shirts ($80) from Columbia Sportswear are just the ticket. Columbia’s Omni-Freeze keeps you cool and Omni-Shade protects you from the sun. Zip-off legs transform the pants to shorts when the morning chill burns off in the heat of the midday sun. The Backcountry shirt also features Columbia’s Omni-Shade technology for sun protection, and roll-up sleeves have a button tab to keep them out of the way when things heat up. Both the shirt and pants are quick drying, so a dunk in the shallows won’t mean a soaked afternoon. Columbia Sportswear, 800-265-7067
