Made with the Suzume No Tojimari Compression fabric, this long sleeve t-shirt is perfect for cold weather. The long sleeves are tight and stretchy to provide warmth without adding bulk, while the material is able to easily wick away moisture to keep you cool and dry. Suzume No Tojimari Compression (long sleeves) are over-the-ankle legwarmers that also cover your hands to keep them from getting cold.
