Founded by a trio of athletic pals, LeftLane Sports vends top sporting gear and apparel brands boasting deep retail discounts. Among outdoors products, camping carryalls such as High Sierra Explorer 55 backpacks ($59.95) soothe shoulders with padded straps, and waterproof leather shoes by Teva ($44.95) keep tootsies dry during nature hikes or sober during grape-stomping tournaments. Ruffle-hemmed Fila skorts ($19.95) help tennis divas upstage homely opponents, and Puma running shorts with refractive trim ($17.45) keep nighttime joggers from being confused with local ninjas. With sport-specific Bern helmets ($39.95+), skateboarders, snowboarders, and wake-boarders can safeguard noggins from gnarly wipeouts. Buyers may use the value of their Groupon toward the cost of shipping. LeftLane Sports ships most orders in one business day.
