It doesn't get much more comfortable than this. Its extra-stretchy fabric moves with you, not against you, so you never feel held back on the course. Soft anti-pick, anti-pill fabric is extremely breathable & lightweight. Material wicks sweat & dries really fast. 4-way stretch material moves better in every direction. Mock neck collar for added coverage. . . . . . . 92% Polyester/8% Elastane.
