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.

Full length insulated boot cover
Easy and fast to put on in the cold and at high altitude
Fits over double shelled mountaineering boots, and large volume single mountaineering boots
Completely stretchy to fit a wide range of boot models
Fit with a wide range of crampons styles
Easy to repair

The Forty Below® Purple Haze™ model overboot is knee height, and completely insulated using a special nylon covered, 5mm stretchy neoprene closed cell foam insulation. The insulation goes completely around and under the boot, with no gaps in the insulation. The insulation panels are glued together, and also stitched on the inside and outside surface, with no sewn through seams. They fit trim to the boot, and are not bulky.
They fit with a wide range of crampon binding styles such as “step-in”, “new-matic/hybrid”, and “strap-on” crampon bindings. The toe and heel areas have small triangular shape panels made of a slightly thinner neoprene insulation that allows for many wire toe bails and flip lever heels to simply compress the insulation and rest on the toe and heel groove of the boot.
A thin rubber paint for added abrasion resistance and additional protection for the stitching is applied on the toe, heel, and lower side areas. This adds some nice added durability to these key areas, and retains the ability for the overboot to be stretchy.
The closure is in the front using a special large size YKK® HEAVY DUTY zipper, with an insulated neoprene fabric flap underneath to help keep snow out and heat in.
Forty Below® overboots are very easy to repair and maintain. The common crampon poke holes are easily glued back together. Please see the info sheet provided with the overboots, and also the Repair Section of this website for more details.
Other uses in camp: We also use these overboots as a sit pad in camp, as a cover for camp booties to add insulation and keep snow out, stuff them with extra clothing to make an “L” shaped pillow in the tent, as an “insulated bag” to put water bottles with Forty Below® Bottle Boots™ on them inside to help keep water from freezing as fast overnight, and can also be added underneath a sleeping pad to add extra insulation in areas desired.
ORDERING: Please use the fill-in boxes above to provide information about your boot and we will select the proper size overboots for your boots. We need your boot Brand, Model, Size, and a measurement of the bottom of the sole from the heel to the toe. Measure using either inches or cm.
OVERBOOT SIZING: Forty Below® Overboots are made with stretchy insulation materials, and have a wide range of different sizes and shapes of boots that a particular overboot model/size can fit. Because of this wide range, we ask that you provide some basic information about your boot and crampon, and then we will select the proper size with that information for you. Please use the fill-in boxes above for ordering.
SIZES: XS-XL to fit from ladies 4 to mens 16 double shelled mountaineering boots.
COLORS: Black, Red. (Purple and Pink not available at this time, hopefully back again in Spring/Summer of 2023)
WEIGHT: Lightweight! Only 20 oz.! (560g) per pair size Medium.
