Collapsible Pure Titanium Hydration Bottle

Measures 18.5 cm tall when fully expanded and 7.5 cm in diameter; collapses vertically to approximately 6 cm height for minimal packing volume. Net weight: 120 grams. Holds 500 ml of liquid. Made entirely from commercially pure titanium (ASTM Grade 1), with no coatings, linings, or composite materials — ensuring complete biocompatibility and thermal stability. The curved carrying loop is an integral part of the titanium rim, not an add-on. Supplied with a compact, form-fitting organizer pouch made from durable 210D nylon with YKK zipper and bartacked stress points. This bottle operates via controlled wall flexure — no moving parts, hinges, or gaskets — meaning zero maintenance, no degradation over time, and consistent performance across thousands of compression cycles. Titanium’s natural oxide layer provides passive corrosion resistance ideal for sea cliffs, forest trails, or high-altitude environments where moisture and abrasion are constant factors. Designed for users who demand reliability where failure isn’t an option: road cyclists needing vibration-dampened, silent carry; ultralight backpackers counting grams per item; mountaineers requiring gear that functions at sub-zero temperatures; and eco-conscious adventurers avoiding single-use plastics or BPA-laden alternatives.
