Located across from Denver's flagship REI store, Wilderness Exchange Unlimited feels like a smaller version of its retail neighbor, a two-story temple to skis, backpacks, boots, climbing gear and everything else you need for playing in the mountains. But unlike REI, Wilderness Exchange specializes in sniffing out cheap deals on overstock, seconds and lightly used consignments and passing them on to customers, so you can get shred-ready without shredding your credit rating in the process. The shop's knowledgeable staff and generous demo program, which lets patrons test-drive six ski setups for $120, makes deciding where to sink your money a snap.
