## Long description

Buff Thermonet Crew socks in navy blue, size 42–44, are mid-calf thermal performance socks designed for cold-weather use. Constructed from Thermonet fabric, they combine insulation and moisture management to keep feet warm while allowing breathability and quick drying. Reinforced zones at the heel and toe enhance durability and maintain fit during outdoor activities or daily wear.
Advantages
These thermal crew socks provide balanced insulation without excessive bulk, helping maintain foot temperature in cool conditions. Thermonet construction promotes efficient moisture transport away from the skin and accelerates drying, reducing the risk of discomfort from dampness. Reinforced heel and toe areas increase longevity, while the mid-calf length offers protection and compatibility with a wide range of footwear. The navy blue colour offers a neutral look suitable for outdoor and casual use.
Suitable for
Hiking and trekking in cool weather
Everyday wear during autumn and winter
Outdoor work and field activities requiring thermal socks
Travel where compact, quick-drying socks are needed
