What is the best base layer under a drysuit?
The model that most divers have come to adopt ever since fourth element launched the first base layer—the xerotherm—designed exclusively for drysuit diving, is a good base layer, a thermal mid-layer (or two), and an outer shell. When considering wetsuit vs drysuit, it’s important to note that dry suits offer significantly better waterproofing and thermal protection, making them ideal for colder conditions or extended use.Diving suit, Wetsuit, Survival suit, Hazmat suit. The main difference between dry suits and wetsuits is that dry suits are designed to prevent water from entering.Nowadays, most drysuits will be fully breathable to allow the moisture out of the suit as you sweat on the inside. If this moisture wasn’t able to escape, it would leave you feeling damp and cold on the inside, which would defeat the point of the drysuit.Bottom line, it’s easy to get cold even when you wear a drysuit. But with a little attention to what you wear underneath, every dive can be like a tropical vacation.Neoprene Drysuits Neoprene is thermally insulating so the need for additional thermal layers is reduced but neoprene is also buoyant because it is full of tiny air bubbles which is what helps to provide that insulation. The trouble with air when diving is that it compresses as you go deeper.
What is the most critical feature of a drysuit?
Keeps You Warm in Cold Water The most significant advantage of a dry suit is its ability to insulate you from cold water temperatures, crucial for preventing hypothermia during long dives in cold environments. Bottom line, it’s easy to get cold even when you wear a drysuit. But with a little attention to what you wear underneath, every dive can be like a tropical vacation.Unlike drysuit seals, semi-dry suits intend to let in a small amount of water. This function, paired with the neoprene layer, means your body heat can quickly heat the water inside the suit. The warm water and trapped heat in the nitrogen bubbles of the neoprene keep you warmer for longer.Everyone has their own limits for how cold the water must become before switching from a wetsuit to a drysuit, but as a rough rule of thumb, you might decide to switch if you are diving in temperatures lower than around 60°F/15°C for recreational diving.Unlike wetsuits, which trap a thin layer of water and preserve body heat, dry suits are waterproof. When considering wetsuit vs drysuit, it’s important to note that dry suits offer significantly better waterproofing and thermal protection, making them ideal for colder conditions or extended use.
How to choose the right drysuit?
The first thing you want to do is check that the drysuit does not excessively constrict your neck or wrists. Ensure the seals are good, that they are flush against your skin. Make sure that the drysuit allows you a full range of movement. Neoprene suits stretch well, but there should still be space for a layer. On the other hand, having a drysuit that is too tight will restrict your movement and make it difficult to carry out tasks. Therefore, as a general rule of thumb, buy the smallest size that allows a good range of movement with layers underneath. Try on the suit, crouch down and walk around to get a feel for the suit.The lifespan of a drysuit can vary widely depending on several factors, including the quality of the suit, the materials used, how well it’s maintained, how frequently it’s used, and the conditions in which it’s used. On average, a well-maintained drysuit can last anywhere from 5 to 15 years or more.Drysuits are expensive and should last for many years – take the time to get the fit you want. Height and weight are typically the most important markers for size. While the suit may not offer a perfect fit out of the box, your height/weight will give you the best size to start with.
What is the nrs ascent drysuit?
The NRS Ascent SAR Dry Suit features an adjustable neoprene comfort-neck and neoprene wrist gaskets that are less constricting and still seal out the majority of water. Constructed with durable 3-Layer TriTon™ fabric for dependable waterproof-breathable protection. Front-entry YKK® Aquaseal™ zipper. Common dry suit material like Trilaminate, vulcanized rubber, coated fabric, and even crushed neoprene suits have little insulating properties. Dry suits made of these materials require the diver to use an undergarment and add air or argon to the suit to stay warm.Choose the right undersuit In this case, look for an undersuit which is low in bulk and will allow freedom of movement, but still offer good thermal protection, or, for warmer waters, choose a thermal baselayer. We designed the Arctic undersuit for use underneath neoprene drysuits.
