Fourth Element Subxero Undersuit Jacket

Product Description

Fourth Element Subxero Undersuit Jacket The Sub X has been developed for use underneath membrane & trilaminate drysuits & all independent testers have rated it as the warmest undersuit they have tried. Windproof, & waterproof. the suit consists of a jacket & salopette or 'farmer john' giving maximum protection to the body core. It will also continue to provide thermal protection if it becomes wet, either by a leak or more fundamental suit failure. The outer material is a trilaminate material comprising a nylon/polyester outer & microfibre inner, bonded to a breathable, but waterproof membrane. The inner material is a 400g shearling fleece, which provides high performance thermal protection & wicks moisture away from the skin. The Sub X has been designed with the dive & the surface interval in mind. Practical pockets double as vents during the dive to help prevent air being trapped in the suit, cuffs at the wrists & ankles are adjustable & a large vented patch on the arm has a wind proof backing to prevent windchill when not wearing a drysuit, but allowing air to escape from the auto dump when diving. Pocket Vents The pockets on the jacket & 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. This helps to prevent air becoming trapped & speeds up the process of dumping air from the dry suit. Arm Vents The arm vent is made from a stiff mesh material, ensuring that it will allow easy air release, through the shoulder dump, without interfering with the dump valve. The interior fabric at this point has a windproof lining, which prevents windchill through the arm vent during the surface interval, making the jacket useful in its own right. Removable Crotch Strap The removable crotch strap helps ensure that the jacket remains in place & does not ride up during the dive. The strap is attached with pinch clips & can be easily removed after the dive. Overall Features The Sub X 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, & the collar provides additional weather protection between dives when not wearing the drysuit.
