Engineered for backcountry self-sufficiency, this compact multi-functional titanium bottle filters and purifies water at the source, then transitions seamlessly to camp duty. Boil water in the Titanium Outer Cup directly on your backpacking stove, or nestle it among hot coals. The 0.5L UltraPress® removes viruses, bacteria, and protozoa while filtering out sediment, chemicals, pesticides, herbicides, and heavy metals. Exceptional strength-to-weight ratio meets expedition demands. Compatible with drink mixes and electrolytes.
