My wife used it for sports other than volleyball. There are no tears or holes. Please comment if you have any concerns. Thank you. It is made of a material that is stretchy, sweat-absorbent, and quick-drying. The D-slit cut (armhole specification) reduces stress during arm raising and rotational movements. The fabric in the armpit area is made of a material that does not fray even without stitching, reducing bulkiness in the armpits. The back is sewn to avoid the shoulder blades, allowing for ease of movement around the shoulders. The elbows are treated with a slip finish, designed for flying receives. Based on the baseball undershirt (product number: STD771), the silhouette has been set to fit the slender physique of volleyball players.
