Grade 1 pure titanium — no lining, no coating, no compromise on what goes into your cup. The Keith Ti3521 double wall mug and tea infuser system is built for the person who takes their tea seriously enough to not want the vessel interfering with what's in it. Pure titanium does not react with theophylline or caffeine, produces no heavy metal ion migration, and alters zero flavor from the first steep to the last sip.
The double wall construction keeps your drink hot without burning your hands, and the two-lid system — one pure titanium, one food-grade silicone — gives you options depending on whether you're steeping, drinking, or keeping heat in between sips. At 450ml, it's the right size for a proper solo brew at camp or on the trail.
