Women’s Seamless Long-Sleeve Training Top with Thumbholes – for Functional Fitness

Cold-morning runs, rower intervals, wall balls in a chilly gym: a fitted long sleeve keeps you covered without getting in the way. This women’s seamless long-sleeve training top is knitted in one piece, so there are no side seams, and thumbholes keep the sleeves in place when you pull, row or throw.

Features

• Seamless knit construction: no side seams, with knitted contour lines and a breathable mesh-knit panel down the back.
• Thumbhole cuffs: sleeves stay down over your wrists on runs and rows, and don’t ride up on overhead work.
• Raglan sleeves and crew neck: free shoulder movement for SkiErg pulls and wall balls.
• Fitted, stretchy cut that layers under a hoodie or windbreaker.
• Fabric: 100% nylon knit. Plain, logo-free design.
• Lightweight: about 6.3 oz (180 g).
• Sizes 4, 6, 8, 10. Colors: Slate Purple, Burgundy, Royal Blue, Espresso.
