What Our Gearhead(R) Experts Are Saying:"I grabbed the Baby Nano Puff Jacket for my niece for chilly stroller walks, and it kept her warm without any extra bulk. The zippered handwarmer pockets were a nice touch for cold little fingers."Cold mornings are no match for the Baby Nano Puff Jacket, the layer we reach for before heading out into brisk air. Patagonia builds it windproof and water resistant with a recycled polyester shell, so a little wind or a stray drizzle never slows down the day. The lightweight PrimaLoft insulation keeps warmth in without weighing little ones down, making it easy to move, wiggle, and explore.
