This 200 ml (7 oz) capacity running bottle with hand straps and an anti-drip sports lock cap. This water bottle for running is made of high-quality silicone that is totally safe to use. Mini water bottle was designed with a push-on cap and cross valve, to prevent water leakage even during running. Bite the silicone mouth lightly or press the spout with fingers, then easy to suck the water out. The wristband of the bottle cover is approximately 7.8 inches in length, and it can be adjusted to the appropriate length. Really convenient, comfortable, and easy to use.
