ThermaCheck®-200 fleece is the ultimate in year-round versatility - slightly thicker and warmer than our lightest ThermaCheck-100. This new top features snap fastening, instead of the usual half-zip. It's a perfect layer of soft, lightweight warmth you can wear over a shirt or tee when it's milder, and under a coat when the mercury really plummets. The fabric is comfortable and practical - drying quickly after washing, with special finishes to reduce static cling, repel lint/pet hair, and minimize pilling.
