Sub Zero Factor 1 Plus Unisex Short Sleeve Seamless Thermal Base Layer Tops are snug fitting and have plenty of stretch (100%), making 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.
The innovative seamless body construction incorporates stretch rib zones for enhanced support and waffle zones for increased thermal efficiency and greater control of perspiration.
The Sub Zero Factor 1 Plus Unisex Short Sleeve Round Neck thermal base layer underwear are great in the winter for layering over the top of a round neck long sleeve thermal base layer to give extra thermal layers without adding bulk to your lower arms. This is especially useful for cyclists, canoeists, runners and rowers.
For extreme temperature use in conjunction with the Factor 2 range of mid layer thermal underwear.
