Athleticism is more than dodging projectiles, wrangling mascots, and dropkicking a computer after it beats you in chess. Outfit yourself for adventure with today's Groupon: for $15, you get $30 worth of outdoor gear at Army Navy Outdoors, with locations in North Lauderdale, Jacksonville, Davie, and West Palm Beach.

Army Navy Outdoors keeps its shelves stocked with military-grade field gear, heavy-duty outerwear, and military apparel. Dry off with a quick-drying microfiber towel ($19.99), whose lightweight fabric can pack down to a very small size, fitting in bags such as the Alice pack ($22.99), which stows personal effects in its plethora of pockets. Corded reusable earplugs ($10.99 for a pack of 10) can be called to duty for protecting eardrums in wood shops or muffling the sounds of fledgling Who cover bands. Army Navy Outdoors also outfits its customers with a plethora of camouflage gear, including rip-stop nylon pants, which greatly increase the chances of succeeding at hide-and-seek games based in army surplus stores.
