F1 Long John (Fly) Base Layer Thermal Leggings Xlarge Black

Sub Zero Factor 1 garments are one of the most technical range of base layer thermal underwear available.They are manufactured from a lightweight rib Tactel fabric designed to be worn next to the body. Each fibre is treated with a hydrophilic finish that transports moisture away from the skin and disperses it over a large area of the outer layer of the fabric, so it can easily evaporate. This snug fitting garment has plenty of stretch (100%) which makes it feel as comfortable as a second skin and allows for a close comfortable fir for most body shapes. The stretch, coupled with a high rise back will prevent lower back exposure under active conditions that may cause discomfort and cold spots.
