Keith Titanium Titanium Sport Bottle
Single-wall pure-titanium bottle with a titanium screw cap - the drink only touches titanium and one silicone sealing ring.
The verdict: Silicone only
The body is Grade 1 pure titanium with no lining or coating, and the cap is a titanium shell - so the only non-metal part your water contacts is a food-grade silicone sealing ring in the lid. That makes it silicone-only, not fully plastic-free: Keith markets it as "plastic-free," which is true for the titanium body and cap shell, but the seal is silicone, not titanium. For a purist who wants no plastic and is fine with a silicone gasket, titanium is lighter and more inert than steel.
What it's made of
| Part | Material | Water contact |
|---|---|---|
| bottle body Grade 1 pure titanium, single-wall, no lining or coating | Titanium | Yes primary |
| cap shell threaded titanium cap | Titanium | Yes primary |
| cap sealing ring food-grade silicone sealing ring - the only non-titanium part in the water path | Silicone | Yes seal |
A single-wall bottle made entirely of pure titanium, prized by ultralight hikers because titanium is roughly 45% lighter than stainless steel at the same strength, imparts no metallic taste, and will not corrode or shed a coating. It's an open-mouth bottle with a threaded cap - no straw or spout. Sold in 400ml, 550ml, and 700ml sizes with a cloth sleeve; a larger wide-mouth bayonet-cap version (Ti3035/Ti3036, 0.9L/1.2L) uses the same titanium-plus-silicone-seal construction.
Pros
- Body and cap are pure titanium - no coating, no plastic, no metallic taste
- Far lighter than a comparable steel bottle
- Titanium is highly corrosion-resistant and does not retain flavors or odors
- As close to plastic-free as a leakproof bottle gets, short of a gasketless steel cap
Cons
- Single-wall - no insulation, and the body gets hot/cold to the touch
- Expensive relative to steel bottles of the same size
- Open-mouth style; no straw or spout option
Notes
- Sizes: 400ml / 550ml / 700ml sport bottle (threaded cap); 0.9L / 1.2L bayonet-cap wide-mouth versions
