Arc'teryx Eon SLW Boxer - Women's - $64.95

You may think, 'Wool underwear' Um, not a fan of underwear that feels like sandpaper.' Fortunately, the Arc'teryx Women's Eon SLW Boxer feels nothing like sandpaper; in fact, it feels silky, smooth, and quite awesome on your touring-toned bum. Merino is a super-smart choice for active underwear: it dries quickly, stretches, allows perspiration to evaporate right through, and insulates even when snow-sogged.
