Proven comfort and mobility comes from years of experience in building lightweight full body harnesses. North builds quality and comfort into its harnesses and the Vest-Style is no different. Adjustable shoulder straps and a chest strap that can be positioned in the optimum location for the user, eliminate the need for stretchable webbing. Proven polyester webbing provides added UV protection and chemical resistance. All North's harnesses designed for use in North America are made with a sub-pelvic strap to add comfort and help distribute the forces generated in a fall.
