Drysuits & Undergarments

A drysuit proves to be an invaluable asset for divers exploring cold water environments, offering unparalleled protection against the chill. Unlike wetsuits, drysuits create a watertight seal, preventing water from contacting the skin and insulating the body with a layer of air. This design not only keeps the diver dry but also allows for the customization of thermal undergarments to suit varying temperature conditions.

Cold Water Wetsuits

The thickness of the wetsuit plays a crucial role, offering varying degrees of thermal protection suitable for different cold water conditions. Beyond insulation, wetsuits provide excellent buoyancy and flexibility, allowing for unhindered movement underwater. Their simplicity and ease of use make thick wetsuits a popular choice for divers exploring colder environments, ensuring a balance of warmth, mobility, and safety throughout the underwater adventure.

In addition to traditional wetsuits, semi-dry wetsuits have gained popularity among divers seeking enhanced thermal protection. Semi-dry wetsuits strike a balance between drysuits and standard wetsuits, featuring improved seals at the wrists and ankles to minimize water exchange. This design helps to keep a thin layer of water between the body and the suit, which is then warmed by body heat, providing additional insulation against the cold.

Fleece-lined dive skins and rashguards are popular choices for adding an extra layer of insulation beneath the wetsuit. This added layer not only traps additional warmth but also wicks away moisture from the body, keeping the diver more comfortable during extended periods in cold water.

Hoods, Boots & Gloves

Hoods, boots, and gloves are indispensable elements of cold water diving gear, playing a crucial role in preserving body heat and ensuring a safe and comfortable underwater experience. These accessories provide essential coverage for extremities that are particularly vulnerable to heat loss. A well-fitted hood prevents heat from escaping through the head, a major source of body heat dissipation. Boots not only shield the feet from the cold but also provide insulation against the often frigid temperatures at the bottom of bodies of water. Similarly, gloves not only protect the hands from the biting cold but also maintain dexterity, enabling divers to handle equipment and perform essential tasks underwater.
