Thermal - The Theory of Keeping Warm ...

SealSkinz® socks and gloves keep your hands and feet dry, which helps protect them from the cold.

A primary mode for heat loss from hands and feet is conduction; the transfer of heat through a substance. This occurs when there is a temperature difference between the body (the heat source) and the external (colder) environment. Heat loss is slowed by clothing, which determines how far the heat to travel before it escapes. Air is a poor conductor of heat, and consequently an efficient insulation material. Water conducts heat 24 times more effectively than air, and is therefore a poor insulator. SealSkinz® products are waterproof, and so the spaces in the fabric are filled with air, not water – SealSkinz ®therefore slow heat loss much more effectively.

SealSkinz® Performance ...

The most effective way to keep hands and feet warm is to provide as much insulation material as possible and therefore slow down heat loss. The SealSkinz© mid thermal sock has terry loops on the internal surface and incorporates a special hollow core polyester yarn. Both of these mechanisms are designed to trap as much air as possible.

To maximise thermal protection, the SealSkinz® sock and glove liners are specifically designed to be worn under SealSkinz® waterproof products. These products are made from Meraklon, a thermal yarn which traps air whilst being very lightweight. SealSkinz® liners are worn under waterproof gloves and socks, where they are protected from getting wet and can trap air not water.
