Spring weather can be all over the map. Add a breathable, waterproof outer layer like Columbia's Trail Drier Windbreaker Jacket into your workout gear arsenal and you'll never let a sudden shower catch you off guard. Omni-Wick EVAP technology wicks away sweat so you won’t overheat, and Omni-Shield coating repels water so you’ll stay dry. When the sun decides to heat up mid-run, simply shed the jacket, bundle it up, and stuff it into its easy-pack pocket—then get right back on the road. ($90; columbia.com)
