These Womens 5mm Snorkelling Wetsuits are designed to provide comfortable thermal protection in waters with temperatures between 20 and 28 degrees Celsius which can include destinations such as the Red Sea. Due to the lower water temperatures that these types of wetsuits are designed for these suits use more advanced seals that help to significantly reduce the amount of heat water that is lost.
5mm thick wetsuits will start to introduce baffle seals that allow for a layered seal approach when used with gloves or boots. Some suits have a zipped section on the wrist and/or ankles that is folded back, the gloves or boots go over the top of the inner layer and the outer layer is folded back and zipped to create a seal on overlapping layers that also reduces flushing in and out of the boots and gloves.
The neoprene quality also starts to become important because as it gets thicker it also becomes more rigid and restrictive. Manufacturers use a clever combination of stitching and panels cuts to minimise the effects but suits that use high or ultra stretchy neoprene allow for far better freedom of movement. This advanced neoprene is however more expensive.
A wetsuit is usually made from foamed neoprene and is designed to provide thermal insulation when snorkelling or engaged in other water sports such as scuba diving. Water conducts heat away from the body 20 to 25 times more efficiently than air which is why we rapidly become cold when in water or feel the cooling effects of wind when wet. A wetsuit works by massively slowing the passage of heat from the body to the surrounding water by placing tiny gas bubbles and thermal layers that act to trap or hinder heat loss. This relies on the wetsuit fitting snugly, especially at the seals so to prevent the heated water inside the suit from escaping and cold water from entering. Although flexible neoprene seals help to prevent this it is vitally important that the wetsuit fit well in the first place.
