This purple 500ml collapsible silicone water bottle is the easy way to carry water without carrying bulk. The flexible, food-contact-grade silicone body extends for a full 500ml of hydration, then compresses down short when you're done, and the stainless steel cap locks in a leakproof seal for trips in backpacks, purses, and carry-ons. The included aluminum carabiner clips the bottle to a bag strap or belt loop, and the wide mouth makes filling, drinking, and cleaning simple at camp, in the gym, or on the road.
