Most ultralight hikers refill the same disposable Smartwater bottle for hundreds of miles. The problem is PET. It's brittle, sheds microplastics into your water as it ages, and was designed for one use, not a thousand. NOBO is a 64 g HDPE bottle made in the USA. HDPE is denser and more chemically stable than PET, built to hold up over the long haul. It uses the same 28-410 thread as Smartwater, so it works with the Sawyer Squeeze, Platypus QuickDraw, and most common filters. Tethered cap that opens with one hand. Chamfered drinking lip. Carbonized oz/ml markings that won't rub off. On cold nights it doubles as a hot water bottle in your sleeping bag. Boil-safe, dishwasher-safe, and easy to keep clean over thousands of miles. Backed by a lifetime guarantee. Specs: Capacity: 1 liter Weight: 65 grams Dimensions: 240mm height x 81mm diameter Materials: Bottle - HDPE Thread: 28-410 (compatible with common filters) Markings: oz and ml (carbonized for durability)
