Overview
A 64 ounce stainless steel water bottle built around a triple layer wall of steel, copper plating and a vacuum gap, rated to keep drinks cold for up to 48 hours or hot for up to 24. Suited to hikers and gym users who want a half gallon of capacity without swapping to a hydration pack.
The bundled carrier bag does more work than it first appears: a shoulder strap, carabiner, small phone pouch and key hook turn a bare bottle into something you can actually carry on a trail. A compass is thrown in too, though at this size a full bottle is meant for a backpack or hip carry, not a jersey pocket.
- 18/8 stainless steel inner wall with copper-plated middle layer
- Spout lid plus straw lid included
- Carrier bag with shoulder strap and carabiner
- Braided handle rope and compass included
Who it's for
Fits hikers, gym-goers and anyone who wants a single fill to last most of a day rather than refilling a smaller bottle repeatedly. Less suited to anyone who wants a light bottle for running, since 64 ounces of steel and liquid adds real weight.
Pros and cons
- Half gallon capacity from one fill
- Carrier bag adds a phone pouch and key hook
- Wide mouth accepts ice, easy to clean
- Comes with spare straws and two cleaning brushes
- Heavy to carry once filled with liquid
Performance notes
The cold and hot retention numbers come from a vacuum gap paired with a copper-plated middle layer, the same principle used in higher end thermoses: the vacuum blocks conduction and the copper plating reflects heat back inward. Real world retention will run shorter than the rated 48 and 24 hours once the lid is opened repeatedly through the day. The wide mouth that makes it easy to add ice also makes it easier to lose some of that insulation with each open and close.
