The Nano Puff® Pullover’s modo is versatility. It’s an insulated pullover in spring squalls, a sleek micro-belay parka on chilly rock routes and a thermal midlayer all in one.
The Nano blocks wind, sheds snow and traps heat - even when wet - with the best available synthetic insulation: PrimaLoft® ONE (60-g) is incredibly warm, low-bulk, compressible and hydrophobic.
Patagonia improved the fit with more shaping through the torso and waist, and refined the deep-venting half-zip with a soft, wicking interior storm flap and zipper garage.
The 100% recycled polyester ripstop shell glides effortlessly as an outer or midlayer, and it all packs down to practically nothing and stuffs into a single chest pocket that has a carabiner clip-in loop. Elasticized cuffs and hem seal out wind and trap warmth.
PrimaLoft® uses a patented microfiber structure to help the body retain warmth and conserve energy. Available as PrimaLoft ECO or PrimaLoft One.
