Making the Jet Pack more comfortable to wear?

[drewfett]

I just purchased an ROTJ Fett costume and must say the jet pack is heavier than I expected. I was wondering if anybody has any tips on making the pack more comfortable? Thanks.

JP made from fiberglass or something else?
What is the jetpack harness? The harness makes a big difference in weight distribution. I like BigDane's harness. http://www.thedentedhelmet.com/f31/quality-jetpack-harness-kit-51562
