Factor 1 Long Sleeve Thermal Base Layers are snug fitting unisex thermals that have plenty of stretch (100%) which makes them feel as comfortable as a second skin and allows for a close comfortable fit for most body shapes. The stretch, coupled with long cut, will prevent the garment from rucking up under active conditions that may cause discomfort and cold spots on the lower back. The super efficient hydrophilic finish will wick perspiration away, leaving your skin feeling warm and dry.
These are ideal thermals suitable for all outdoor sports including skiing, canoeing, running, cycling, walking, polar expeditions, military maneuvers and mountaineering. For extreme temperature use in conjunction with the Factor 2 range of mid-layer thermals.
