===Neoprene===

Neoprene spray decks are snug, elastic, and tight fitting on the kayak or canoe cockpit, and have very little or no leakage when well fitted. They sit tight across the cockpit rim with little sag, so water sheds quickly rather than pools on their surface. They typically remain in place during water impact better than other types, so are the usual choice for white water rivers, surf, and sea kayaking.  They remain in place during paddler actions of rolling and bracing. They are warm to wear, due to the neoprene tube around waist and lower trunk. They come in many sizes, to suit the shape and size of the cockpit rim and the waist of the wearer. The rim of a neoprene spray deck is elasticated, typically with either shock cord, or a rubber/elastomer rand. Models designed for casual use to just prevent splashes from entering the craft will typically have light shock-cord, making them easy to fit.  Models designed for severe use such as for descending waterfalls are heavily elasticated so they remain in place, but require significant arm strength to fit.  Neoprene spray decks may be fitted with additional reinforcement of wear resistant fabric on the front part of the deck, to reduce damage during boat-to-boat rescue and emptying.
