Throw on the GSX Performance Quarter-Zip Mock Jacket for your next workout and you'll stay dry, light, and ultra-comfortable. Lightweight, high-stretch 100% polyester fabric wicks away moisture to keep you cool and is treated with an anti-pill finish for long-lasting wear. An antimicrobial treatment helps reduce odors so you stay fresher longer. Flatlock seaming throughout allows for easy layering, while reinforced coverstitching in high-wear areas provides enhanced durability. The quarter-length front zipper extends through the top of the mock-neck collar to further protect against chilly air. The brushed chin guard resists chafing for superior next-to-skin softness. A zip-secure pocket at the left chest provides convenient storage for your small essentials. GSX silver reflective heat transfer logo at the center back. Imported.
