Sub Zero Factor 1 Unisex Vest Thermal Base Layer Tops are snug fitting with plenty of stretch (100%) which makes it 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.
This is an ideal thermal base layer for adding extra protection to your core under other base layers, or for discretely wearing under work wear when commuting.
For extreme temperatures use in conjunction with the Factor 2 range of mid-layer thermals.
