Collapsible Water Canister 2L/3L, Filter Ready Ultra-Light | HydraPak Seeker

Stop carrying bulky, rigid plastic bottles that take up space even when empty. The HydraPak Seeker is the ultimate heavy-duty, ultra-light collapsible water storage solution engineered for long-haul expeditions, overlanding rigs, and backcountry survival. Designed for extreme durability, this flexible canister provides high-capacity hydration without the weight, compressing down to the size of a fist when not in use. For effortless organization, the 2L model comes mission-ready with a dedicated 10x10 cm tactical storage pouch. Forged from abrasion-resistant TPU with RF-welded seams, the Seeker series is built to survive the harshest environments. This advanced radio-frequency welding technology guarantees reliable, leak-proof, and elastic seams that withstand heavy pressure. The low-profile, coated bail handle allows for effortless pouring and carrying, while the flexible design ensures it folds down beautifully and easily when empty. Its versatile construction allows it to be frozen or filled with hot water (up to 140°F) to be used as a high-performance heat pad or warm-water bottle in survival conditions. The Seeker is a versatile mission-ready tool for water management. Featuring a standard 42 mm threaded opening, it integrates seamlessly with industry-leading filters like the Katadyn BeFree. Its universal design allows the vessel to function as a high-capacity hydration reservoir or connect to specialized gravity systems. By using a Plug-N-Play cap and a 28 mm filter adapter, you can easily adapt the Seeker to various filtration and dispensing setups, making it the perfect centerpiece for camp water management. Built for maximum utility, the Seeker features four load-bearing side lash points for securing to a pack, hanging from branches, or setting up a gravity-fed hydration station. The leak-proof screw cap includes a tear-resistant tether that doubles as a carrying loop, keeping the Seeker upright during filling. Constructed from 100% BPA and PVC-free materials, including high-strength TPU and HDPE, it is completely dishwasher safe (top rack). Ditch the disposables and carry a legendary vessel built for a lifetime of adventure. PRO-TIP FOR PEAK PERFORMANCE: To prep your seeker for a lifetime of service, wash thoroughly with mild liquid detergent and rinse before the first trek. For maximum efficiency in camp, use the four side attachment points to hang the unit for a hands-free gravity filtration setup. Fully compatible with all 42mm threaded filtration systems.
