Warm, heavyweight breathable fleece set Make the outdoors their playground with the top-to-bottom warmth of the toddlers' Fleece Base Layer Set. It's the layering lesson that rolls from PJs to the mountain to keep kids toasty, dry, and ripping all day long. Features: Heavyweight DRYRIDE Ultrawick fleece has plenty of stretch and a grid-backed design for breathability and ultra-fast wicking. Two-way stretch and anti-piling fabric set kids up for lasting warmth and softness. A regular fit, non-tech look, and a soft hand give them an easygoing feel you can wear anywhere.
