Inherently waterproof, the 905 EXP drysuit is made from Parmasoft™ trilaminate, a three-layer material consisting of a six-ply butyl rubber core sandwiched between two-ply layers of durable polyester. The polyester layers add exceptional puncture and abrasion resistance yet have the ability to stretch along with the core material for maximum flexibility. This “trilaminate” construction minimizes drag compared to neoprene and rubber suits, allowing for more efficiency in the water. For extra durability and survivability, the 905 incorporates knee, elbow, and shoulder protective pads ensuring those areas of the suit hold up to the pressures of diving. As always, the 905 uses seams that are ultrasonically welded, not sewn. This patented seaming systemguarantees a gas tight and watertight suit. With the gas in and the water out, you stay warmer and comfortable throughout the dive. A low-profile yet heavy-duty TIZIP waterproof zipper is made to withstand the stress of repeated donning and doffing. The TIZIP construction leads the way over traditional metal zippers in its durability and ruggedness. The included lubricant keeps the zipper performing dive after dive. The Si Tech swivel inlet valve and adjustable, automatic exhaust valve quickly and efficiently inject and exhaust gas allowing for fine tune adjusting of the suit for total comfort and buoyancy control. With the included 31-inch low-pressure inflator hose, the system is complete. Durable latex neck and wrist seals work to keep water out even with bending and flexing. With the ability to trim the seals to size, a comfortable fit can be obtained with little effort. For extra warmth, a neoprene warm neck collar comes standard and works great with most any drysuit hood. A hybrid design with rubber soles and toe and a neoprene body and upper, the 905 boots provide warmth and durability yet allow for excellent flexibility creating a more comfortable and better fitting boot. Incorporating the same daisy chain design as our harness pockets, the 905 has two bellows thigh pockets with daisy chain loops for attaching our line of cutting devices. Inside each pocket is a lanyard to clip off tools and keep them secure when removing them for use underwater. For divers desiring a specialized suit size, the 905 EXP is available for custom order. Every diver can dive the 905 drysuit.
