The Nalgene Sustain Silo is a 48-oz wide-mouth bottle made from Tritan plastic that includes recycled content in the resin. It holds 1.5 quarts, stands 11.25 inches tall and weighs about 7.4 oz empty, so it carries a lot of water for very little weight. The wide opening takes ice cubes and fits standard Nalgene lids and most 63 mm accessories, and the bottle is dishwasher safe and BPA-free. It suits hikers, gym-goers and desk workers who want one big refillable bottle; against insulated rivals it keeps no cold for hours, but it is far lighter and easier to clean.
