Nalgene Sustain 32 oz Wide Mouth Water Bottle: Room for Ice

A few ice cubes can make the water you take out the door more inviting. The Nalgene Sustain 32 oz Wide Mouth Water Bottle makes adding them straightforward: unscrew the cap and fill through the broad opening. This Aubergine version pairs a translucent purple body with a cap that stays attached by a loop, so there is no loose lid to set beside the sink.

The attraction extends beyond that first refill. You can see the water against the printed measurements, and the open neck gives you access when it is time to wash the bottle. Those are useful everyday details for a bottle moving between a desk, a gym bag and a daypack.

Room for ice, with an open rim for drinking

Nalgene specifically designs this wide mouth to accept ice cubes. That is helpful when you want iced water without finding cubes small enough for a narrow neck. The Tritan Renew plastic body is uninsulated: easy ice loading does not mean prolonged cold retention. The opening also leaves room to add drink powder.

Once the cap is off, you drink from the open rim. There is no built-in straw or small drinking spout to meter the flow. Tilt gradually, particularly when the bottle is full. If you mainly want quick sips while walking, decide whether that open-rim style suits you before choosing it for the size alone.

Nalgene sells an Easy Sipper insert separately for its 32 oz and 48 oz wide-mouth bottles. The company describes it as controlling splashes. That option may appeal if you want the filling access but prefer a smaller drinking opening; it is an extra component to buy and clean, not part of this single-bottle purchase.

The markings help you choose the fill

The ounce and milliliter marks provide an approximate visual reference for the fill level. They are useful for judging a partial fill or roughly adding water for a drink powder. If the mixing instructions require an exact amount, use an appropriate measuring container. Keep the line you are reading visible while filling.

A short trip with a refill available may call for less water than time away from a tap. Choose the amount for the outing, rather than automatically filling to the top.

To help preserve the printed markings, follow Nalgene's advice to keep abrasive grit away and wash your hands after applying sunscreen before handling the bottle.

Nalgene lists the empty bottle at 6.25 ounces, about 177 grams. That is the container's contribution to what you carry; the water adds its own weight. Judge carrying comfort with that filled load in mind, especially when the bottle will spend the outing in your bag.

A simple cap, a bottle you can reach inside

The screw closure is central to carrying it. Nalgene attributes its leakproof design to the threads that seal the cap against the bottle. Seat the cap properly before packing it. The tether keeps the cap with you during a refill, but the screw closure still needs to be shut for transport.

Nalgene's published specifications list a 3.5-inch body diameter and 8.25-inch height. Compare those figures with your bag's bottle pocket or cup holder, including its shape and the space around it. A narrow or tapered holder can be a poor match for this broad bottle.

For everyday cleaning, hand wash the bottle and cap. A bottle brush can reach through the neck to clean the interior; pay attention to the cap's underside and the threads as well. Rinse both parts thoroughly.

After rinsing, leave the cap open so air can reach the interior. Nalgene recommends letting the bottle dry fully and storing it uncapped in a cool, dry place. Set it where the opening stays clear, rather than screwing the lid shut just to put the bottle away.
