Men’s and Women’s Running singlets are designed to have a Racing Running fit, and moisture management advantages, with 1-2” of ease.
This is the lightest, most breathable fabric available. You will feel like you aren't wearing anything. It is borderline mesh, but also features a UPF sun protection rating of 30.
The fabric has a four way stretch allowing it to fit next to and move with the body in motion.
***If you prefer a looser fitting top it is recommended that you size up. The singlets are usually 1 size smaller than the Tech Tees. They are a " race cut" vs a "club cut" ***
