Maintaining a balance between the heat your body produces and the heat you lose to the outside environment is essential, and an integrated multi-layered clothing system that fits well, doesn't restrict movement and weighs as little as possible is the key.

A light polyester layer next to the skin will wick moisture away from the body and a fleece mid-layer will protect you from the cold. Both fabrics dry very quickly, and maintain warmth without weight even when damp.
Protective outer shells in Gore-Tex® or Tropos fabric are absolutely waterproof and windproof from the outside, yet allow moisture and perspiration vapour to escape from the inside. The result: you stay drier and more comfortable.

Salt water does not harm these fabrics or affect the performance in any way as salt water crystals are much too large to clog the pores in the membrane.

Salt accumulation does attract moisture so rinsing your garments in fresh water is important. If fresh water isn't available, rinse in salt water. Salt water is only 3% salt.

A breathable Dry Suit or Semi-Dry one piece suit is a comfortable option under any conditions as you can regulate the warmth of the system by adding or removing layers underneath.
