Men’s Thermocline Vest
£105.00
The Men’s Thermocline Vest provides lightweight, neoprene-free thermal protection designed to enhance warmth without restricting movement. Ideal for wearing under a wetsuit, it adds thermal insulation equivalent to an additional 2mm of neoprene while remaining neutrally buoyant, breathable, and comfortable for diving and watersports.
Perfect for scuba diving, freediving, snorkeling, paddling, and other water activities, this versatile vest helps keep your core warm while allowing complete freedom of movement through the arms. Lightweight, quick-drying, and machine washable, it is a practical addition to any water sports kit.
Description
The Men’s Thermocline Vest is designed to provide targeted core warmth while maintaining flexibility and comfort in the water. Constructed using advanced Thermocline fabric technology, it offers a neoprene-free alternative for divers and watersports enthusiasts who want additional thermal protection without the bulk and buoyancy of traditional neoprene layers.
Worn beneath a wetsuit, the vest delivers insulation comparable to an extra 2mm neoprene layer around the body’s core. It also helps reduce the sensation of cold water entering through wetsuit zippers, significantly improving overall warmth and comfort during dives. Because the vest is neutrally buoyant, it enhances thermal performance without requiring additional weight adjustments.
The innovative multi-layer fabric combines a soft fleece inner lining with a breathable membrane and durable nylon outer surface. This system helps wick moisture away from the skin while promoting breathability and comfort when preparing for a dive, during surface intervals, or while participating in paddle sports and other surface activities.
In the water, the breathable membrane helps retain a thin insulating layer next to the body, reducing heat loss and improving thermal efficiency. The sleeveless design maximizes arm mobility, making it an excellent choice for diving, paddling, kayaking, snorkeling, and other activities where unrestricted upper-body movement is essential.
The vest also performs exceptionally well as a standalone thermal layer for warm-weather watersports. Paired with Thermocline shorts, it provides lightweight core protection for summer paddling and recreational water activities. Quick-drying, machine washable, and highly packable, it is an easy-care garment that travels well and remains fresh between adventures.
