The SFI 16.6 Hybrid II belt is a patented Schroth design belt, no other manufacturer offers a belt with sub-straps that directly load the lap belts. The Hybrid belt is an excellent belt for those who find the T-bar style belt uncomfortable. By placing the sub-straps through the lap belts, this provides more space for the new Negative G belt. The Hybrid II is commonly run as non-adjustable lap belts but a Pull-up right side lap belt is available. The Hybrid belt is offered in 3 different shoulder belt configurations; an all 3â€, a 2â€/3â€ HNS specific shoulder belt and the Double shoulder belt.
