The first thing you will notice when donning Hybrid Pro Tec is the perfect fit. This new level of comfort is achieved via special shoulder pads which are longer, pre-shaped and reinforced, and which work in perfect unison with the lumbar suspension system. Hybrid Pro Tec feature 10 metal D-rings, 3 of which can be slid up and down along the shoulder pads, to accommodate any configuration needs. Made of very tough Alutex material, it will endure any exposure you submit it to and hold up to the test of time. Furthermore, Hybrid Pro Tec is a modular BCD: the detacheable vest comprising the MRS plus system is removable, leaving a lean-and-mean travel BCD. This configuration can be expanded by adding the optional lumbar trim weight system and/or the Cruise Add-on pocket.
