The Reima Hopper Fleece Sweater is a knit fleece jacket made from 90% recycled polyester with a soft, sweater-style melange finish. Its quick-drying knit wicks moisture out to the fleece's outer layers, keeping kids warm whether it's zipped under a shell or worn on its own indoors. What Our Gearhead(R) Experts Are Saying:"My kid came in soaked from sledding, and this was dry again before the next trip outside. It's the only piece I trust to go straight under a shell without adding bulk on the coldest days."
