Rab Carrington (as in the Rab in Rab!) originally devised the Vapour-Rise concept by combining the technology of high wicking micro fleece & Pertex Equilibrium fabrics to produce a single garment with a 2 layer construction that offers superb weather protection & immense breathability. These exceptionally comfortable softshell pants are incredibly versatile & offer year round protection for outdoor activities by balancing warmth, windproofing & breathability; what more could you need? The 2 layer Vapour-Rise technology uses your body heat acts as a pump working with the micro fleece brushed lining to push moisture away from your skin & move it to the face fabric. Pertex Equilibrium face fabric has larger filaments on the inside & smaller filaments on the outside. The laws of capillary action dictate that moisture will move from large filaments to smaller ones, pulling your sweat away from the lining & spreading it out over the large outer surface area. This evaporative heat loss & moisture wicking create a temperature equilibrium to keep you comfortable & dry in all conditions. Finally a robust DWR treatment on the outside repels water. The Vapour Rise Pants features an unrestricting part-elasticated waistb&, stretch panel on the seat & anatomical knees for ease of movement & user comfort. You can wear these pants on their own or with a baselayer for extreme conditions. We recommend using a silky smooth baselayer material under Vapour Rise garments to ensure they glide smoothly against the VRs wicking liner & to maximise the wicking properties.
