Headset Hole: Includes a dedicated cutout at the top to allow wired headphones to pass through easily.
Materials: Made from water-resistant and sweat-proof fabrics like polyester, Oxford cloth, or PU, with a breathable mesh back for comfort against the skin.
Adjustable Fit: Uses an elastic strap with a strong Velcro closure that typically fits arm circumferences between 15 cm and 40 cm.
