During a cold and wet scramble along the Lake Districts Helvellyn mountain in 1967, Derek Laxton hit upon inspiration for a technical range of thermal underwear. With a trained mechanical engineer background and a lust to run his own company, in 1969 Sub Zero Technology Ltd was created. From their original Leicester textile mill, the Sub Zero Factor 1 range of thermal base layers was born to worldwide acclaim.

In the five decades since, Sub Zero have expanded their range to include heavy weight thermal mid layers through to insulating down jackets. Never a company to stand still, Sub zero have adopted new manufacturing processes, such as seamless knitting technology and body mapping, to produce garments that are at the pinnacle of performance.

Sub Zero today is still family owned, with the third generation of Laxtons running the company. The factory and offices now reside in rural Leicestershire, with the workforce coming from the local communities. Sub Zeros work ethos is still true today as it was form its interception - to design and manufacture technical outdoor clothing using the finest technical textiles for the words most extreme conditions.
