Forty Below K2 Overboot Description

  • Season :
  • Code : FBE K2OB
  • Packaged Weight : 0.64KG
  • The K2 Superlight overboot is a great choice for extreme cold climbs and particularly designed for beefing up the warmth of leather boots. A favorite insulated over-gaiter that has been used for many years on Denali, Himalayas, and Polar expeditions. The unique design allows it to be used with a wide range of crampon binding styles such as step-in (Crampomatic), semi-step-in (Newmatic) , and strap-on (New Classic) crampon bindings, as well as wire toe ski mountaineering bindings. Patterned to fit both plastic and leather mountaineering boots. In addition to being used with double shelled boots for high altitude and cold weather climbs, they can also be fitted to leather climbing boots to help extend their temperature use range. Thus the K2 is patterned to fit both plastic double boots and single leather mountain boots. It does not have insulation in the upper, so it can be used in "less cold" conditions also, for situations such as with boots like the La Sportiva Nepal EVO, etc. So this overboot can be sold for two different kind so of boots and situations, both high altitude on double boots, and on leather boots to help extend their range. The K2 has a crampon patch on the side and a non stretch gaiter fabric so it will not fit on the ski boots. It is not as warm as the Purple Haze but is better for more technical climbing.

    The Forty Below® K2 Superlight uses a special nylon covered, 4.7 mm stretchy closed cell neoprene foam insulation, with 2 layers of heat reflecting Titanium. This insulation goes from about the top of your climbing boot, 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. Because of the stretchy insulation material they are easy to put on in the cold, and they roll up small in your pack.

    The toe and heel area 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. The toe, heel, and lower side area of the overboots have a thin rubber paint applied to add abrasion resistance and help protect the stitching. A 2 inch wide heavy duty velcro front closure goes all the way down to the toes for easy adjustment of laces. The upper gaiter goes up to just below the knee, and is made of a non-coated, windproof and breathable Cordura nylon to help minimize frost build up. Elastic drawcord top closure, with a cordlock on top of the gaiter. A special smooth nylon crampon patch is glued and stitched to the instep side of the neoprene for added resistance to crampon pokes, etc.

    One of the great features of Forty Below® overboots is that they are easy to repair! This is especially helpful, as crampons and rugged terrain are so hard on everything they come in contact with. Repairing is easily done by simply gluing the poke holes together, using glues such as those for repairing neoprene fishing waders or wetsuits, like AquaSeal from McNett, etc. For the fabric gaiter repairs, the iron-on style fabric patches work well and are really easy to put on, and can in many cases eliminate the need to sew patches on. For repairs on the mountain, use the Forty Below® Repair Patches, which are a special sticky and stretchy tape that work great for repairs during a trip or McNett Tenacious Tape.
