SilverAnt 0.8L Titanium Water Bottle Review
Potential health concerns associated with the ingestion of micro (1 µm to 5 mm) /nano (1-100 nanometers) plastic particles have led many backpackers to seek alternatives to plastic water bottles, particularly single-use bottles like Smart Water bottles. The SilverAnt titanium bottles (made in China) are such an alternative.  Transitioning from plastic to this durable, multi-use option also addresses the environmental impact of single-use disposables while providing a bottle built to last decades on the trail. SilverAnt provides a lifetime guarantee on defects in materials or workmanship. Customer service is reported by users as excellent.
The SilverAnt 0.8L (28.1 fl) all-titanium bottle isn’t as light as plastic, but at 6.7 ounces (190g), it may be a suitable option for gram-counting backpackers. The brushed Ti, single-wall construction allows direct heating over camp stoves, a versatile feature that can come in handy on cold evenings or for warm drinks.
Due to its combination of strength, moderate (approximately 30 W/m·K) insulating ability, and biocompatibility (non-corrosive and non-toxic), titanium is used in the aerospace, medical, and marine industries, where these properties are critical. However, titanium comes with tradeoffs. Its moderate insulation means that drinks can both warm and cool quickly. If desired, the bottle can be placed directly onto a flame (stove or campfire) to heat without damage. To maintain internal fluid temperatures longer, and provide additional surface protection, SilverAnt provides an easy to carry tight fitting, insulating thermal sleeve. that not only protects the bottle but also insulates the bottle’s contents. The bottle comes in both narrow and wide mouth openings. While easy and quick to fill, drinking with the wide-mouth while walking can be awkward and potentially messy on uneven ground. Filters such as the Sawyer Squeeze doesn’t fit the wide-mouth. The bottle’s tall, narrow profile makes it easy to fit into a backpack side or front pocket, but it can be a bit tippy when placed on irregular surfaces.
Build quality is solid, with clean welds and a brushed metal surface. The secure titanium screw-top lid has a clip top for attachment to a pack or for easy carry. Though the top’s metal threads feel less smooth when tightened than plastic and can cross-thread if you’re not careful in low-light conditions, it fits tight, feels smoother with regular use, and doesn’t leak. If this is undesirable, a second top, with silicon-lined threads, is also provided.
While its durability, lack of plastics, and insulative properties can be attractive, its weight and price point might be too high for hikers who choose to use cheaper and lighter disposable plastic options.
For backpackers concerned about the health impacts of microplastics, prioritize durable, dual-use gear, and don’t mind the limitations, the SilverAnt Titanium .8 L water bottle could be a suitable option.
