Everything: No more connection between the sleeve and arm wing -- it's no longer a wingsuit-style armpit / leading edge assembly. An all new "winglet" provides an ideal solution to the drag problems of a fully inflated sleeve, giving the pilot power and control in the arms, with minimal drag. The result is 100% arm range of motion, plus a solid and sharp feeling of control from the arms, thanks to the winglet and a tapered arm wing leading edge.
The Mutation 2 features slightly more surface area and a more efficient leg wing. In the BASE environment, glide performance is useless if your trackwingsuit is not stable, easy, and fun to fly. The fun & ease of the Mutation series is obvious - it is simple in transitions, backflying, and freestyle flight, and the glide performance is top of class. The result is true performance -- a trackwingsuit that gets you there, with ease.
Comfort is getting small wingsuit glide performance while resting your hands on your BOC -- you can literally rest your hand on your PC handle while flying at >2:1 LD. Transition & backfly with ease, thanks to the winglet's power and the suit's balanced feel. Do whatever you want with your arms and legs, thanks to full range of motion and a longer stride.
