CW-X fleece lined 1/2 zip long sleeve for winter sports activities! Wicking material and mock turtleneck helps keep you warm. Marked size L, but I wear more of a M and it fits. It is super stretchy material. No issues. Very gently used. Thumb holes in wrists. Measures unstretched- 23” long in front 25” in back, 17” across chest, 21” sleeves. The CW-X Insulator Zip-T for women is a high-tech base layer. The zip turtleneck is built with Auto-Sensor nanotechnology fabric offers insulation and wicks moisture.
