You are here: Factor 1 Plus > Factor 1 Plus Bloo John Seamless Thermal Underwear Base Layer

Thermal underwear seamless base layer unisex leggings are snug fitting and 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 a high rise back will prevent exposure under active conditions, protecting your kidneys and lower back from discomfort and cold spots. The super efficient hydrophilic finish will wick perspiration away, leaving your skin feeling warm and dry.

The innovative seamless construction incorporates stretch rib zones on the abdomen, knee and the side of the leg for enhanced support and waffle zones between the thighs and the back of the knee for greater control of perspiration.

This is the ultimate in thermal underwear base layer technology and is suitable for all outdoor sports where extra warmth is required but without the bulk: Lightweight walking, climbing, skiing, and cycling. For extreme temperature use in conjunction with the Factor 2 range of mid layer thermal underwear.
