The REI heavyweight MTS underwear top for women is an excellent first layer for mountaineering and other high-energy, cold-weather activities. Quick-drying and moisture-wicking, ultrasoft MTS microfleece draws perspiration away from skin to keep you warm, dry and comfortable. Zip T-neck with deep zipper allows ventilation control; zipper has soft backing to avoid chafing. Droptail hem stays tucked in and offers extra coverage in back. All seams are flatlock stitched to avoid abrasion and bulk. Close-fitting cut increases top's thermal efficiency. Closeout.
