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 $25, you get $50 worth of outdoor apparel and gear at 123Mountain in Lakewood.

123Mountain outfits nature enthusiasts with everything they need to enjoy the great outdoors, from sleeping bags and tents to men's and women's clothing. Hike from classroom to campsite with a light yet durable Kompressors Lowe Alpine bag ($40), or sport a silkweight Patagonia long-sleeve, which is made of moisture-wicking fabric ($45). A serious selection of sunglasses ($20+) keeps woodland creatures looking cool, and men's Skins half tights ($75) improve circulation while minimizing the body's drag coefficient. Shoppers can also pick up functional fashion accessories such as the M-9 Suunto wrist compass ($33.95) to avoid getting lost in the forest or in a particularly poorly groomed backyard.
