"The Patagonia Triolet Pant is built for days that cross the line between lift-served skiing and the alpine, the kind of objective where the approach demands as much as the descent. The GORE-TEX ePE 3-layer laminate and PFAS-free DWR treatment work together with the double-cuff gaiter system to keep weather out from the waist to the boot interface, so the pant holds up whether the day ends at the lift or at a summit. When the angle steepens and the terrain gets consequential, the concealed RECCO reflector adds a passive layer of rescue-system visibility that costs nothing in weight or bulk. What Our Gearhead® Experts Are Saying:""The full-length side zips let me pull these on and off over ski boots without sitting down in the snow. That matters when transitioning at a windy col and every second counts."""
