The use of GoreTex fabrics makes the suit comfortable to work in and breathable, allowing the sweat of exertion to be released. The extremities, such as feet, hands and head, also need to be considered. Ski goggles are also considered essential to keep out the stinging salt-water spray. Trying to work a knot out with frozen fingers can be both painful and dangerous. All layers are detachable allowing different combinations to be worn, and are easily removed for rope handling.
Feet are particularly vulnerable to constantly cold and wet conditions.
If feet are not kept warm and dry, a debilitating condition known as 'trenchfoot' can occur. Waterproof socks and fleece liners keep the feet warm and dry, and gaiters seal the suit and sailing boots together. The final important accessory is a readily available sharp knife. This is carried at all times, often round the wrist in a sheath. The knife is used to undo stubborn knots and, in emergencies, to cut snagged lines that might cause injury or endanger life.
