Layering has always been the secret to a warmer dive. If you stay warm while underwater you get longer bottom times, loose less heat for multiple dives in one day and reduce fatigue and the chance of decompression sickness. The Akona Quantum Stretch Hooded Vest is made with 4-way stretch neoprene that gives the most comfortable fit you have ever worn. A unique rubberized neck panel and an exterior seal provide warmth and reduce the amount of water entry. Combined with an Akona wetsuit, the hooded vest works perfectly to create a glide-skin neck seal which prevents water from seeping in between the suit and the vest. All this means more comfortable and enjoyable diving!
