SubX

SubX - The Ultimate Undersuit

The SubX thermal undersuit has been developed for use with membrane and trilaminate drysuits, and all independent testers have rated it as the warmest undersuit they have tried. Windproof and waterproof, the undersuit consists of a jacket and salopette or 'farmer john' giving maximum protection to the body core. The SubX will also continue to provide thermal protection if it becomes wet, either by a leak or more fundamental suit failure of the drysuit. This is an undersuit designed for extreme diving conditions and has been tested in temperatures of -2°(29F).

further information

The SubX undersuit jacket has been developed for use underneath membrane and trilaminate drysuits. The jacket has a large arm vent on the left arm to enable air to escape more easily through the shoulder dump valve. The undersuit's inner lining is a 400g shearling fleece, which provides high performance thermal protection and wicks moisture away from the skin.

The SubX undersuit Salopettes has been developed using a trilaminate material comprising a nylon/polyester outer and microfibre inner, bonded to a breathable, but waterproof membrane. The inner material is a 400g shearling fleece, which provides high performance thermal protection and wicks moisture away from the skin. The Salopette adds a second layer of thermal material under the SubX Jacket for extra warmth.

The SubX undersuit 2 piece set has been developed for use underneath membrane and trilaminate drysuits. The Salopette adds a second layer of thermal material under the SubX Jacket for extra warmth.

The SubX is 100% machine washable, but should not be tumble dried. If the suit gets wet during diving without access to a washing machine, the suit can be dried by turning it inside out then rolling the garment from the bottom upwards to remove any excess water, then hanging it to dry. The collar can be turned down to avoid interfering with the neck seal of the drysuit, but in most cases this is not necessary, and the collar provides additional weather protection between dives when not wearing the drysuit.

SubX - Features

subx features

SubX Jacket Features: The pockets on the jacket are zipped for security, but the pocket lining is a mesh, allowing the pockets to be opened to act as vents during the dive. This helps to prevent air becoming trapped and speeds up the process of dumping air from the dry suit. The removable crotch strap helps ensure that the jacket remains in place and does not ride up during the dive. The strap is attached with pinch clips and can be easily removed after the dive.

SubX Salopette Features: The pockets on the salopettes are zipped for security, but the pocket lining is a mesh, allowing the pockets to be opened to act as vents during the dive. A two way zip ensures ease of access for routing and fitting p-valves, as well as going to the bathroom. Stirrups made using the inner lining fabric, fit around the foot and ensure that the trousers do not ride up the legs during donning.
