Features

Premium 99.8% Pure Titanium
Made from high-purity titanium — rust-proof, corrosion-resistant, high hardness, and built to last. Titanium is chemically inert and won't affect the taste of your drinks.

One-Second Threadless Lid
Replaces the traditional screw cap with an upgraded push-open lid that opens and closes in one second — perfect for one-handed use on the go.

Double-Wall Vacuum Insulation
Inner and outer walls are both 99.8% titanium with a vacuum layer in between. Keeps drinks hot in winter and cold in summer all day long — enjoy ice water on a summer hike or hot coffee on a cold morning.

Refined Detail Design
The threadless top features smooth, rounded edges for a comfortable drinking experience. The non-slip silicone base keeps the bottle stable and quiet on any surface.

Leak-Proof Silicone Seal
The lid is fitted with a silicone sealing ring for a high-integrity closure. Carry it in your bag all day — no drips, no spills, no worries.
