Star Wars Mandalorian jetpack
Vacuum formed Nite Owl style, missing beacon (I can 3D print that for you if you need it). fabulous for Bo Katan or female Mando costume or cosplay, lightweight. Can attach via a harness plate similar to pics 2 and 3(harness NOT included). I have also seen assorted people screw these directly to back plates or use Velcro or safety chain locks.
