When days shorten, Death Valley conditions turn brutally bone-chilling. The Infant Capilene Set comfortably protects little ones against harsh exposure to sun and cold, packs tiny, dries fast, fights odor, goes on easy and is incredibly soft-wearing. Made of 88% recycled polyester/12% spandex-sueded jersey fabric, the two-piece baby baselayer has Polygiene permanent odor control and a wicking finish for excellent moisture management. Sleeves have self-fabric fold-over mitt to keep hands extra warm. The bottoms have an elasticized waist, knee patches and an expanded back gusset for extra diaper room and mobility.
