Octa Half Zip Shirt

A half‑zip shirt constructed from Octa® fabric, engineered to be about half the weight of standard polyester fibers of the same diameter. The unique radial protrusions on the surface absorb and diffuse sweat quickly while trapping dead air for insulation. Designed as an active insulation piece, it can be worn comfortably across long seasons, with a drawcord hem for fit adjustment.
