ArmaSkin liner socks utilise proprietary Silicone Fusion (SiFusion) technology to generate novel performance characteristics in the skin, liner sock and outer sock combination.

The inner surface is a fine, porous coating of silicone. This holds firm against the skin while the non-treated external surface of the ArmaSkin is very smooth, allowing external movement to be deflected instead of being transferred to the skin layers as destructive shear forces.

The silicone layer is also hydrophobic, ie water hating, which means that moisture, ie sweat or river water, is pushed to the outside of the liner sock to be wicked away by the outer sock.
