The Forty Below® Purple Haze™ overboot is the choice of climbers for Denali, the Himalayas, and cold weather expeditions worldwide. 

The easy to put on, full length insulated overboot for mountaineering, the Forty Below® Purple Haze™ overboot is patterned to fit over double shelled and single mountaineering boots.  The Purple Haze™ model is a very unique overboot in that it can stretch to fit easily over a wide range of double shelled mountain boot models, and also the large volume “combi-boots” such as those from Millet, La Sportiva, etc. They also fit nicely over large volume single mountaineering boots such as the La Sportiva Nepal for example.  It is important to point out that they no longer will fit over any type of AT ski boots or snowboard boots anymore, as those types of boots have changed in their shape, so we now make the Forty Below® Fresh Tracks™ model for those boots.

The Forty Below® Purple Haze™ is easy to put on in the cold and fits trim to the boots and leg area.
