Pure Titanium Lightweight Collapsible Bottle

Fully expanded: 18.5 cm tall × 7.5 cm wide; collapses to ~6 cm height. Holds 500 ml. Total mass: 120 g. Constructed exclusively from ASTM-certified Grade 1 titanium — free of nickel, lead, cadmium and phthalates. Seamless draw-formed body with cold-worked rim and integrated curved loop. Supplied with a compact organizer pouch made from tightly woven, water-repellent nylon with bar-tacked corners and a smooth-gliding zipper. The bottle’s mechanical design leverages titanium’s unique combination of low density and high elastic limit — allowing deep, reversible compression without buckling or permanent set. Interior surface is electropolished for smoothness and ease of cleaning; exterior has a fine-grain satin texture to improve grip and reduce fingerprint visibility. Fully dishwasher-safe (top rack) and compatible with UV-C sterilisers. Optimised for active lifestyles where gear must earn its place: urban cyclists navigating rain-slicked streets; trailblazers crossing boggy moorland; alpine climbers managing gear in thin air; and sustainability-focused users replacing disposable bottles with a lifetime solution that improves with age — not degrades.
