Boundless Voyage Titanium Water Bottle
Silicone is only a gasket/seal — what touches your food is Titanium.
Lower-cost pure-titanium bottle - buy the solid-titanium-lid version so the drink touches only titanium plus a silicone seal.
The verdict: Silicone only
The body is 99.8% pure TA1 titanium with no coating, and Boundless Voyage offers models with a solid titanium lid rather than a plastic cap. In that configuration the only non-metal part in the water path is a food-grade silicone seal - silicone-only. It's the budget alternative to Keith in titanium drinkware.

Boundless Voyage makes ultralight titanium drinkware at noticeably lower prices than Keith, sold largely through marketplaces like Amazon. Bodies are 99.8% pure TA1 titanium with no lining, and most models are single-wall.
Pros
- Pure titanium body, no coating, no taste transfer
- Meaningfully cheaper than Keith for similar titanium construction
- Ultralight for backpacking
Cons
- Product line mixes titanium-lid and plastic-cap variants - easy to buy the wrong one
- Material documentation is thinner and scattered across listings
- Single-wall on most models - no insulation
Notes
- Also sells vacuum-insulated (double-wall) titanium models alongside the single-wall bottles
