Breeztex Windproof, Breathable, Fleece-Lined High Neck Long Sleeve Innerwear - 3 Pieces - Colors: Black, Gray, Light Gray - Design: High Neck, Long Sleeve - Set Contents: Set of 3 This item uses "Breeztex," an ultra-thin windproof and breathable film that prevents cold wind from entering and releases moisture from the skin to prevent stuffiness. Thank you for viewing. I purchased this from Shop Channel and have stored it at home. It is a set of 3 pieces. The fabric is also sturdy. I use the crew neck type, and it's warm. I bought this for my mother, but it seems to be too large, so I am selling it. Shipping costs will be considerable, so please refrain from price negotiations.
