Factor 1 Short Sleeve Thermal Base Layers Unisex Tops by Sub Zero 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.
