This athletic quarter‑zip pullover jacket is made of lightweight stretch performance fabric, combining soft touch, air permeability and moderate elasticity to support body movement during sports. Mock neck design with partial quarter‑zip closure allows flexible ventilation adjustment according to temperature. Adopting sports‑oriented ergonomic cutting, the garment will not restrict shoulder and arm motions. Practical side pockets are reinforced by neat stitching to secure personal items. All internal seams adopt overlock processing to eliminate rough thread ends. The fabric undergoes anti‑wrinkle and quick‑dry finishing for lasting neat look outdoors. Well‑suited for golf practice, hiking, jogging, gym training and daily casual layering. This mock‑neck pullover jacket delivers lightweight comfort and multi‑scene practicality for active men.
