When heading out on an extended trek, reliable hydration is non-negotiable. A high-quality Stainless Flask is the cornerstone of any backpacking kit, designed to withstand the rigors of the trail while keeping your liquids at the perfect temperature. For day-long adventures, the compact 900ml Stainless Flask offers the ideal balance of capacity and portability. For multi-day excursions or group trips, the substantial 1.8L Stainless Flask ensures you have ample water supply without frequent stops to refill. Regardless of the model you choose, our advanced Shockproof Stainless Flask construction provides unparalleled durability, protecting your flask from accidental drops on rocky terrain. Our flasks are engineered for the serious backpacker who demands performance and reliability from their gear.


The Backpacking Stainless Flask is meticulously crafted with the outdoor enthusiast in mind. It features a double-wall, vacuum-insulated body constructed from premium 18/8 food-grade stainless steel, ensuring your beverages stay hot for up to 12 hours or cold for an impressive 24 hours. The flask is completely BPA-free, guaranteeing that no harmful chemicals leach into your drinks. A secure, leak-proof cap with a silicone gasket provides a perfect seal, allowing you to toss it into your pack without worry. The exterior boasts a durable, powder-coated finish that resists scratches and minimizes condensation. An integrated carry handle or a compatible carabiner clip offers versatile carrying options, making it easy to attach to your backpack. The wide mouth design facilitates easy filling and cleaning, while also being compatible with most water filters for purifying water from natural sources on the go.
