The 686 Authentic Smarty Cargo 3-In-1 Pant offers versatile warmth and weather protection for the whole season, from deep powder days to sunny spring runs. Proven Smarty design lets you crank up the heat in January or keep it cool in April, and Infidry-15 fabric shields you from pouring snow, howling winds, and spring slush. A removable fleece liner pant can be worn with the Smarty on cold days to keep your legs cozy, or you can take it out and just rock the shell for sunny spring sessions. And on top of that, you can remove the shell and just wear the fleece pant while you lounge in the living room after a long pow day. In fact, the liner pant features denim-inspired five-pocket styling so you can wear it out on burrito and beer runs later that night. Infidry 15 waterproofing blocks out blowing snow, but is also breathable to keep you from overheating, and fully taped seams prevent moisture from seeping in throughout the day. The regular fit allows room to move comfortably, and cargo pockets provide room to stash your stuff. Air-Flo mesh-lined vents dump heat during intense hikes and leg-burning runs, while the PJ jacket-to-pant connection lets you link up to your 686 jacket to block out snow on deep days. Boa-compatible boot gaiters keep snow from getting in your boots when you're in the deep stuff while still allowing you to access the Boa dial for on-the-fly adjustments, and Cordura-reinforced hems prevent your cuffs from getting shredded.
