Freediving Wetsuits are slightly different from those for scuba diving. The main concern when it comes to Freediving Wetsuits is mobility. You should be able to move quickly and with no restraints. Freediving suits come in either one or two-piece designs. Freedivers often prefer two-piece suits, because they provide more mobility and some additional warmth at the core. As for the material options, you can select between closed-cell neoprene, open-cell neoprene, and Lycra. Closed-cell neoprene suits are very popular thanks to their durability and affordable price. However, they are also somewhat constrictive and less efficient at insulating. Open-cell neoprene wetsuits are much softer and more flexible than closed-cell suits. They also have greater insulating efficiency and provide an excellent range of motion. The downside is that open-cell suits are generally more fragile. Finally, you need to consider the thickness of the wetsuit. Commonly, 1-1.5mm suits are used in warm water, 3-5mm are suitable for moderate water, and 7mm suits are needed for cold water. Remember, thicker suits decrease mobility, so you may want to choose a suit that utilizes a mixture of thicknesses in order to increase insulating ability with minimal impact on your freedom of movement in the water.
