Mens HA Salopettes Full Zip From Buffalo Full length side zips A convenience zip runs from the fly position A zipped map pocket with weather flap Bum, Knee and ankle patches Weight: 870g Pertex 6 Shell with 'AquaTherm' pile lining. These Salopettes are specifically designed for Mountaineering and High Altitude climbing. The specification is the same as the Standard Salopettes with the addition of high tensile patched bum, knee and lower inner leg to protect against damage from ice climbing. The patch fabric, developed by Buffalo, is very breathable, but in low level damp atmospheric conditions it does not allow moisture to evaporate as rapidly as the Pertex it is protecting. Consequently it is not suitable for low level conditions, but is ideal for less humid higher altitudes.Please note that the sizes listed for this item are measured at the chest as the item is a high-bib design.Please note that some items from Buffalo are made to order.
