B2 combines boardshorts style and function into a kite seat harness. The ergonomic leg straps, inspired by the technology of climbing harnesses, have been developed to enable freedom of movement without pressure points. ION's sleek Spectre Bar (incl. kite hook) and C30 buckles complete the ultra-lightweight harness. The detachable Downforce_Loop connects the leg straps with the Spreader Bar and prevents the hook from slipping up. The B2’s Spectre Bar is compatible with the Quicklock Hook. It includes the Kite_Knife Multitool 2.0.
