You can tell there is a bit of a gap in between my leg and the thigh piece. The boxes are held on by velcro,and the shoulder and back piece are held together by velcro on the shoulder.Same goes for the knee cap piece. Is there a way i could secure these pieces other than using velcro? Also, just from taking pictures i can tell that i need to shorten the length on the straps going from the thighs to the belt, where would i buy those straps with snaps or would i have to make them?
