The Marmot Boys' Rocklin 1/2 Zip is a fleece pullover for added warmth in any season. The Rocklin is made with 100 weight micro fleece, making it light enough for a cool fall day and warm enough to boost the heat up under a shell in the winter. Flat lock seams make layering and wearing a pack comfortable. Once he gets too warm from running around, the 1/2 zipper opens up to release excess heat.
