The Patagonia Mas Maipo Tights are built midweight for the kind of activity mix that defines a full day outside, running one hour and climbing the next without a wardrobe change in between. Flat, chafe-free seams and seamless inner thighs hold up through extended wear, while HeiQ Mint odor control keeps the fabric fresh well past a single session. A wide, comfortable waistband stays put under a pack, and drop-in side pockets keep small essentials within reach on the move. What Our Gearhead(R) Experts Are Saying:"I wore the same pair three days straight on a long trek and never once thought about swapping them out, no odor, no chafing, just the same comfortable fit on day three as day one."
