Navy SEAL Divers - Wetsuits
Armed with M4a1 carbines, a pair of Navy SEAL combat divers move out of the water.
The SEALs are wearing diving masks and MK 25 rebreathers - a type of closed circuit SCUBA - over hooded Xcel Infiniti Synergy wetsuits.
They have removed their flippers and have them looped over their right arm.
Wetsuits such as those shown here are made from foamed neoprene, a synthetic rubber.
They provide a degree of thermal insulation and buoyancy for the wearer.
Diving gloves may also be made from neoprene.
