1L Wide Mouth Sustain Water Bottle

The Nalgene 1L Wide Mouth Sustain is a leakproof hiking water bottle made from Tritan Renew, a BPA and BPS free plastic derived from 50% recycled plastic using ISCC certified mass balance. The wide mouth takes ice cubes and fits most water filtration devices. The bottle weighs 177.25 g, stands 21 cm tall and is 89 mm across.

The 1L Wide Mouth is the bottle Nalgene is known for: a straight-sided litre with a wide screw cap on a loop. Nalgene's scientists were keen hikers who took their leakproof lab bottles out on the trails in the 1960s, and the reusable hiking bottle grew from there. This Sustain version is made from Tritan Renew.

Who it's for

Hikers, campers and climbers who want one tough bottle for the track and for every other day of the week. It sits in the middle of the Wide Mouth family, between the 500ml and the 1.5L Silo.

Go for the Wide Mouth if you like ice in your water or you fill through a filter. If most of your drinking happens while you are walking, the 1L Narrow Mouth is the same size bottle with a smaller opening made for drinking on the move.

Capacity and fit

One litre, in a bottle 21 cm tall and 89 mm across that weighs 177.25 g.

• Capacity: 1L (Nalgene's 32oz bottle)
• Height: 21 cm
• Diameter: 89 mm
• Cap: 63 mm
• Weight: 177.25 g

Want less to carry? The 500ml Wide Mouth is 16.5 cm tall and weighs 88.5 g. Want more water? The 1.5L Silo keeps the same 89 mm width and 63 mm cap and grows to 28.5 cm tall.

Drinking and refilling

The wide opening is the reason to choose this one. Ice cubes drop straight in, and most water filtration devices fit the mouth when you need to treat water on the track.

The cap screws down leakproof and hangs from its loop while you drink, so the lid stays with the bottle. If a full-width mouth splashes when you drink on the move, the Wide Mouth Easy Sipper snaps into the neck of a 1L wide mouth bottle to control spills.

Looking after it

The bottle is dishwasher safe: top rack, away from the heating element. Washing by hand works too. Either way, let it air-dry fully with the cap off before it goes back in the cupboard. For a frozen bottle on a hot day, fill it only about two-thirds so the ice has room to expand.
