Chris! That's awesome! Great minds think alike. I see you made it for just the chest. That will save me a step from doing a waist strap as well. Thanks for sharing! Now I'll have mine done in half the time!
BTW, how much does your jet pack weigh? Another question. Is that a small pieces of elastic sewn on the chest strap over the sternum? If so, that's smart. I'd imaging, you need to have some expansion/contraction for moving and breathing.
