Transpac Harness also requires an Air-Cell. Inspired by a remote dive exploration in Japan where divers had to hike their heavy gear through dry portions of cave to get to the underwater sumps. The explorers also needed the versatility to switch their gear configuration from backmount to sidemount to single tanks (flexibility that a traditional hard backplate does not offer). Designed like a mountaineer’s backpack, the TransPac disperses weight across the hips and back, minimizing shoulder strain. Adjustable straps adapt to a wide variety of exposure suits and means easy donning and doffing. A soft backplate accommodates sidemount diving, yet gives appropriate support for single tanks, double tanks or rebreathers. Slots in the back-plate fit standard 36-inch cam straps (included) for single tank diving. The modular design allows for customization using an assortment of pockets and accessories, depending on the needs and desires of the individual diver. The TransPac is lightweight and flattens easily into a suitcase for travel. The TransPac is designed to be used with any wing in the Dive Rite line.Made in the U.S.A.
