Portable Dual-Mode Design The hook-and-loop closure is adjustable up to 18.3cm (7.09 inches) and adapts to different hand shapes. The wristband can be secured while running without having to hold it tightly, and the handheld mode can be switched on to free both hands and provide flexible drinking water. Food-Grade Material The bottle is made of platinum silicone + PP, BPA-free, and the strap is made of Oxford cloth, which is wear-resistant and breathable. It is safe and non-irritating during prolonged contact with the skin and meets the standards of sports health. Leak-Proof Pressing System for Drinking Water The cross valve presses onto the bottle cap. You can bite the silicone opening or lightly press with your fingers to drain water. It automatically seals and prevents leakage when you let go of the bottle. One-handed operation allows for quick hydration during exercise. Ergonomic Wearing Experience The lightweight 200ml (only 80g) design, the elastic hook-and-loop closure on the wristband reduces movement during exercise, and the soft silicone casing follows the curvature of the palm, allowing you to wear it for a long time without feeling bothersome. Suitable for all scenarios The 7-ounce capacity meets the hydration needs of short-distance sports and is suitable for morning jogs, mountaineering, cycling, hiking and other scenarios. The easy-to-clean material can be washed directly or machine washed and is easy to store for daily fitness exercises.
