You are here: Factor 1 > Factor 1 Short Sleeve Thermal Underwear Base Layer

Thermal underwear base layer unisex short sleeve top is 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 underwear base layer for golfing, cycling, hiking and walking where long sleeves may hinder your activity. For extreme temperatures use in conjunction with the Factor 2 range of mid-layer thermal underwear.
