Membrane, Shell and Trilaminate dry suits are made from thin materials, and thus by themselves have little thermal insulation. They are commonly made of vulcanized rubber, or laminated layers of nylon and butyl rubber, this is why they are also known as Tri-Laminate drysuits. Membrane dry suits typically do not stretch, so they need to be made oversized to allow flexibility at the joints through the wearer's range of motion. This makes membrane dry suits easy to put on and get off, provides a great range of motion for the wearer, and makes them comfortable to wear for long periods, as the wearer does not have to pull against rubber elasticity.
To stay warm in a membrane suit, the wearer must wear an insulating Undersuit, today typically made with polyester or other synthetic fibre batting.
Polyester and other synthetics are preferred over natural materials, since synthetic materials have better insulating properties when damp or wet from sweat, seepage, or a leak.
(Except for wool, which is an effective insulator when damp, albeit bulky.)
Northern Diver have a large range of under garments available which include a range of thicknesses, from the thinner Rash Vests and Thermalskin to the more heavy duty Metalux range.
Membrane and Shell dry suits may also be made of a waterproof and breathable material to enable comfortable wear when out of the water for long periods of time. Sailors and Boaters who intend to stay out of the water prefer this type of suit. This type of suit is also supplied to the majority of Fire and Rescue services around the UK by Northern Diver.

Wathaurong (Wadda-Warrung) country
Traditional Owners — This dive site is in the traditional Country of the Wathaurong (Wadda-Warrung) people of the Kulin Nation. This truly ancient Country includes the coastline of Port Phillip, from the Werribee River in the north-east, the Bellarine Peninsula, and down to Cape Otway in the south-west. We wish to acknowledge the Wathaurong as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging. We acknowledge Bunjil the Creator Spirit of this beautiful land, who travels as an eagle, and Waarn, who protects the waterways and travels as a crow, and thank them for continuing to watch over this Country today and beyond.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.
The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
