Questions and Answers for Pinnacle 5mm Siren Merino Elastiprene Super-Stretch Wetsuit:
What size would I need in this if im 100 pounds and 51?
Bob (Certified Scuba Instructor at Scuba.com)
The most important measurements any time you purchase a wetsuit or drysuit using the manufacturer's sizing charts will always be your waist and chest/bust measurements. The suit needs to fit your torso correctly in order to do its job properly. Keep in mind there is no such thing as a comfortable wetsuit on the surface. You want it to be snug, but not cut off circulation to your extremities. The more snug it is, the thinner the layer of water your body is heating. If its too loose you will remain warm for awhile, but eventually your body won't be able to keep up with the greater amount of water flowing through the suit and you'll wind up getting cold faster. After that your height is a secondary measurement. The manufacturers realize that generally speaking your boots and gloves can overlap slightly short arms and legs, or the diver can push or roll up longer sleeves and/or arms if need be. Weight is a measurement the diver can usually ignore. It really has little to no bearing what so ever on the sizing and fit of your suit. The manufacturers do not take into account muscle being more dense than fat, so based simply on fitness levels 2 people can be the exact same size but quite different in weight. This measurement should only be used if the person is literally on the fence between 2 sizes in all categories.

Independent testing performed by the British Textile Technology Group in London, England found that a wetsuit lined with Merino™ is 35% more thermally efficient than a wetsuit made with a traditional lining. Under the new CE testing guidelines, all of PINNACLE’s Merino™ lined suits achieved the highest possible ratings for insulation effectiveness. This proves that PINNACLE’s Merino™ lining system is a superior insulator.
Furthermore, Merino™ lined wetsuits are not as affected by depth as most wetsuits. Any neoprene wetsuit will compress to some extent as a diver descends and the ambient pressure becomes greater. A 7mm suit will become a 5mm suit and a 3mm suit and so on as a diver goes farther down the water column. As the suit compresses, the insulation value of the rubber decreases, and water inside the suit is squeezed out into the environment. Thus, the inherent warmth of the suit itself becomes of lesser value. In traditional wetsuits, with water flowing in and out of the suit, this means that the wetsuit system’seffectiveness is tremendously impaired as the diver leaves the surface.
Merino™ lined PINNACLE suits work far better because they are not as affected by depth and pressure. Though our suits also compress as a diver descends, the water that is absorbed into the Merino™ lining is unaffected by the pressure exerted by the water outside the suit. The lining creates a layer of water, warmed by the diver’s body, which can be as much as 3mm thick. Because this layer of warm water is not compressed by depth, the warmth of the suit system is less affected. So, as the diver descends and the neoprene in the suit is compressed thinner and becomes less effective, the Merino™ lined suit stays nearly as warm as it was on the surface, even on the deepest and longest of dives.
