Engineered for the 40mm housing of the Samsung Galaxy Watch 4, this matte black silicone wristband replaces factory straps with a streamlined, athletic profile that adds visual contrast without increasing thickness. The polished surface feels smooth against the skin, distributing pressure evenly to support seamless wear throughout the entire day.
Synthetic rubber construction actively repels water and perspiration while bending naturally during arm motion. Because the material resists absorption and dries rapidly, it supports high-intensity workouts, trail running, and casual pool or lake swimming. The reinforced core prevents fraying and maintains elasticity after repeated stretching cycles.
