Sub Zero Factor 1 Plus Seamless Thermal Base Layers are one of the most technical outdoor underwear ranges currently available on the market. Their excellent wicking and thermal properties maintains a warm and dry micro-climate next to the skin allowing you to work harder and longer without becoming uncomfortable. The high built-in stretch of these thermal base layers also means they can act as compression aids in muscle recovery.
All Sub Zero Factor 1 Plus base layer garments are manufactured on electronic circular knitting machines from lightweight 100% Polyamide yarn, producing very durable but also very soft thermal base layers that have seamless bodies like our Factor 1 range of base layers. Using these machines enables us to knit in extra features such as stretch rib support on major muscle groups and targeted mesh zones for efficient moisture management, technical designs that are just not possible with the traditional cut and sew process.
Sub Zero Factor 1 Plus thermal base layers are 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 Sub Zero Factor 2 range of mid layer thermal underwear.
