The NXe 4+1 harness was designed with function in mind. The majority of 4+1harnesses on the market use a PP webbed belt with a simple buckle at the front.While this is fine for a recreational 2 or 3 pod pack, like their SP2 and SP3series packs, this belt does not make sense for use on a 4+1 pack, which carriesthe same or more weight than a tournament harness. Their solution? Use a highend elastic belt. The NX-SP41 and NX-SP41CAMO feature a high end body wrap belt,and are constructed of durable polyester.
