Soft Hydration Trail for Cycling Flask, Running, Marathon, Mountaineering, 250ml/500ml, Foldable, Lightweight, Hydration, Trail, (Pink, 500ml)

A soft flask is a vacuum bottle that reduces in volume as the water inside it decreases. Because it's vacuum-sealed, the water doesn't slosh around, and because it's soft, it won't hurt your body when it comes into contact with your running bag or waist pouch. Hydration: Gently squeeze the flask with your hand to push out the contents, then bite the spout to get the water. Even if you have weak sucking strength, you can easily stay hydrated! It's also perfect for sharing water with friends or splashing water on yourself. It's also recommended for the elderly. This product is made of BPA-free, food-grade silicone and durable, flexible TPU (thermoplastic polyurethane). It's harmless, odorless, and highly safe. New bottles have a slight odor. Before first use, filling the bottle with rice water, green tea, sugar cubes, or vinegar can help reduce the odor. Additionally, cleaning with baking soda is recommended. Suitable temperature: 0-40°C. A dust cover is attached to the spout to prevent stains. The foldable bottle is made of soft vinyl, so it can be folded up and made compact when empty. The flask can be stored compactly when not in use, so it won't take up much space in your luggage. Suitable for outdoor sports such as trail running, jogging, marathons, cycling, mountain climbing, hiking, and snowboarding.
