This Ahoodie is made out of California fleece which, opposed to typical synthetic fleece, is made of 100% extra soft ring-spun combed cotton. It's pre-washed to minimize shrinkage, and is breathable yet extra thick for warmth.
Chest: Measure under arms around the fullest part of the chest. Be sure to keep tape level across back and comfortably loose. Waist: Measure around natural waist with a measuring tape. This sizing chart is approximate.
