1L Wide Mouth Ultralite HDPE Water Bottle

The Nalgene 1L Wide Mouth Ultralite HDPE Water Bottle is the lightweight hiking version of the classic Nalgene: a one-litre wide mouth bottle (the 32oz model) made from high density polyethylene that weighs 106.25 g. The 63 mm mouth takes ice cubes and fits most water filtration units, and the bottle is BPA and BPS free and dishwasher safe.

Who it's for

Hikers and campers who count what goes on their back. Carry two or three litres and the bottles themselves start to add up, and this is the one that keeps that figure down: 106.25 g for a full-size one-litre bottle. HDPE takes weight out of your pack and it is still a Nalgene, built to last.

If you want a wide choice of colours, the 1L Wide Mouth Sustain is the one-litre wide mouth bottle in Tritan Renew.

Capacity and fit

One litre, in Nalgene's 32oz bottle. The body is 89 mm in diameter and the cap is 63 mm, the same two measurements as the 1L Wide Mouth Sustain. A scale in millilitres and ounces is printed down the back, so you can measure out water at camp.

Ultralite HDPE vs Sustain: the weight

The 1L Wide Mouth Ultralite weighs 106.25 g. The 1L Wide Mouth Sustain in Tritan Renew weighs 177.25 g. That is 71 g saved on every bottle before you add a drop of water, and it is the reason to choose the Ultralite.

Drinking and refilling

The wide mouth is the easy one to live with. It fills without fuss, takes ice cubes, and fits most water filtration units. The lid screws down on continuous semi-buttress threads that hold the seal, and its loop keeps it attached to the neck while you drink.

If a full-width opening splashes more than you like on the move, the Nalgene Easy Sipper snaps into the mouth of a 1L wide mouth bottle to control spills. And if a lid ever goes missing, the 63 mm replacement Loop-Top lid fits.

Looking after it

The bottle is dishwasher safe on the top rack, away from the heating element. To wash it by hand, fill it roughly two-thirds with very warm water and a little bleach (a few drops is enough), cap it, give it a shake and leave it for an hour before rinsing well. Let it air-dry completely, then store it with the cap off in a cool, dry spot.
