Our new favorite layering piece. We wear it alone and next to skin on crisp fall mornings. We layer it as fall moves to winter and we love it for 9 months a year. Lightweight sweater knit makes for a great thermal piece but the Coolmax is what makes this sweater a top performer. It wicks and warms even when wet. Wash it, dry it, wear it. Repeat. Only at T9. S(4-6), M(8-10), L(12-14), XL(16)
