Boundless Voyage
Like other titanium bottle makers, Boundless Voyage builds the body from pure titanium with no coating, so the drink never contacts plastic. Their leakproof screw caps rely on a food-grade silicone seal, which keeps the bottles in the silicone-only tier rather than fully plastic-free. Some models ship with a solid titanium lid (versus a plastic cap), which is the configuration to buy for the cleanest material path.
How clear are their specs?
Names pure titanium body and food-grade silicone seal, but material detail is thinner than Keith's and is scattered across marketplace listings rather than a single clear spec sheet.
Lead testing disclosure
Marketing leans on titanium's inherent chemical inertness ("100% BPA-free and non-toxic," "will never leach... chemicals") rather than any lead- or cadmium-specific claim, and no dedicated testing/safety page, named lab, or test numbers were found on bvoutdoors.cn or its marketplace listings.
