This bottle cover model has 2 different main uses:
1) for use with metal beverage bottles it helps insulate to help keep liquids cool in the summer, and help reduce freezing and cooling in the cold weather.
2) for use with stove fuel bottles, it has some handy features for use in extreme cold weather, for backpacking and expedition stoves.

The Forty Below® Fuel Bottle Boot™ makes these types of bottles easier to hold on to, and insulate, for helping keep liquids cold or warm.  Practically eliminates the sweating on the outside of the bottle in hot weather…no more condensation moisture dripping off the bottle!  This size fits also on standard 16 oz. bike/sport bottles, and 22 oz Beer Bottles!

If you are using these with fuel bottles typically used for backpacking and expedition stoves, at cold temperatures, it helps you hold on to the bottle better, as metal bottles are slippery, and it insulates to help keep the fuel from gelling at extreme cold temperatures.  It can even add extra stability to a stove when using stoves with the bottle attached, as it helps keep the bottle from moving around on the snow or stove platform.  Covers the sides and bottom.
