What Our Gearhead® Experts Are Saying:“These puffer-alls are a winter win for our little one. Super easy to get on, super warm, and they stay put even through wiggly stroller naps or snow-day crawls. Total peace of mind when temps drop.”When the cold moves in, we want to make sure our tiniest explorers are bundled in cozy, weather-ready warmth—and the Nano Puffer-Alls deliver exactly that. Patagonia’s trusted insulation and thoughtful design keep infants snug and toasty from the first snowfall to chilly campground mornings. The two-layer ripstop shell offers durable defense against the elements, while lightweight and compressible 60g PrimaLoft® Gold insulation provides all-over warmth without bulk. Soft elastic at the cuffs helps seal in heat, and the easy-on design simplifies dressing—because we know getting a baby into gear can be its own adventure. Certified by Fair Trade and bluesign®, these puffer-alls are just as kind to the planet as they are to little bodies.
