The synthetic insulated camp bootie for mountaineering, winter camping, and even around the house! Now your feet and toes can be nice and toasty after a hard day on your adventure! These will be a favorite for all of your trips, year-round! The Forty Below® Camp Booties™ are insulated with a continuous filament polyester fiber, so they dry fast if they get wet. They also provide insulation even if wet, as compared to down/feather insulation which provides no insulation when wet, plus may not ever get dry again during a trip.
This synthetic insulation goes completely around and under your foot. The insulation is a continuous filament polyester fiber, that has been laminated to one side of the shell fabric for stability, and also silicone treated to resist bunching of the fibers and allow for better moisture evaporation. This unique synthetic fill has shown to not tyically bunch/clump-up or compress over time as with most other insulation types.
They are very compact, and superlight at only 10 ounces per pair size medium! The sole is made of a special waterproof rubber material, about 1-2mm thin, that is essentially a rubber/polymer blend that is embossed into a fabric. This gives it the properties of being flexible at super cold temperatures, and grippy with small dot shapes across the entire bottom. There is a Cordura nylon rand around the lower bottom, taffeta nylon upper, and taffeta nylon lining to make them easy to take on and off with wool socks on. Drawstring with cordlock top closure. The new laces offer a great way to add support not found typically in camp booties! The laces are made of a 5/8" wide thin nylon webbing that simpy crosses over the top of the foot, and goes around the ankle and ties in the front. This adds virtually no weight and no bulk as there are no buckles or hardware to get in the way, or cause discomfort when using them inside a mountaineering boot shell around camp. You can also take the laces off and replace with any other lacing, cord, or homemade buckle/strap/velcro.

A very key and helpful feature is the removable closed cell foam footbed, so you can wear the Forty Below® Camp Booties™ inside the plastic mountaineering or ski boot shell when you are drying out the liner. Additionally, by taking out the foam footbed when you want to wear them on your feet while in a sleeping bag, you can have a less bulky, softer and more flexible feel for your feet inside the toe box area of the bag. This is helpful as many foot sections of sleeping bags don't have a lot of room.
Shown in the pictures above is Martin Letzter, who along with Olof Sundstrom of Sweden, is in Antarctica during their successful ascent and ski descent of Vinson Massif. This was the 7th of the famous "7 Summits" , highest in each of the seven continents, that they were trying to ascend and ski descend from! Congratulations! Both Martin and Olof used, and enjoyed, happy warm feet with the Forty Below Synthetic Fill Camp Booties. They had this to report when they returned:
"The Bootie was a welcome addition to the 40 Below product range, and used extensively by the both of us during the expedition to Mt. Vinson last year (where I also noticed that Alpine Ascents guide Eric Murphy also put them to good use). We used the bootie around camp as the only addition to our plastic ski mountaineering boots, as well as as extra protection against the cold inside our sleeping bags at night. They worked very well, and were easier to use while walking on snow and ice compared to many other similar products we have used, thanks to the addition of the insole, providing extra protection from both the cold and uneven terrain that can otherwise make such booties unconfortable to wear. This version however allowed us to spend longer periods outdoors, as our feet stayed warm and comfortable. I hope our feed back can somehow be of assistance to you, and would like to express our gratitude for your continued support. Please feel free to use us as a reference for your products, now that we have completed our project and can affirm that 40 Below will keep you safe and warm while skiing in the coldest conditions that the Seven Summits have to offer."

HERE IS WHAT SOME OF OUR CUSTOMERS ARE SHARING ABOUT 40 BELOW CAMP BOOTIES:

"Awesome trip up and down Shasta...Booties held up well, wore them exclusively outside of climbing and snowboarding around the camp in both total early morning frozen to mid-day loosened up wet snow." Andy G., Posted June 2009

"Attached is the summit photo for Mt. Baker, 5/27/09, and my 40 Below booties made all the difference. It rained from 2:30AM to 8PM on Tuesday and my friend's tent leaked badly. The foot of my down bag got soaked and it was the booties that kept my feet warm. Some members of our party wore down versions by two other companies, and only I had dry feet! It was sure nice to have warm toes as I sat on our snow bench and toasted our accomplishment. Thanks for all your advice." Rob C., Posted June 2009

" I just got home from my semester abroad in Patagonia with NOLS. I, along with just about everyone else, had your booties. I had mine with me for the entire trip - even during sea kayaking! - because they were perfect to wear to bed, especially for someone like me who gets cold when they're sedentary. Everyone had them when we were out mountaineering, and you could often hear people say on the trail, "I want to get to camp and put on my booties." I want to thank you personally, and on behalf of my teammates. The booties worked wonderfully, we talked about them a ton, and thanks to them we rarely had to listen to people complain about cold feet. I will absolutely keep you and your company in mind for the next expedition I take! Thank you!!" P.S. Attached is a photo of me on a mountain in Patagonia. San Lorenzo, the highest peak in Patagonia is behind me. Julie S., From May 2008
