The opinion of Aventure Nordique

The Forty Below Bottle Boot 32oz / 1L is an insulated sleeve designed to slow down water freezing in cold environments. It fits most 1-liter water bottles, including Nalgene 32oz and 1L bottles.

Made of 6.5mm thick closed-cell neoprene foam, this sleeve provides even insulation around the bottle. It limits the cooling of the liquid in winter conditions and can also help keep a drink cold in warm weather.

The front Velcro closure with a pull tab is easy to use even with gloves or mittens. The absence of a zipper prevents the sleeve from freezing shut. A webbing loop allows you to attach the sleeve to a belt, backpack, or carrying strap.

Points to remember

Used for decades, these insulating covers have proven their worth in the coldest conditions: high-altitude expeditions, Arctic conditions. They slow the cooling and freezing of liquids in cold weather but also keep liquids cool in warm weather.
