RE: Who uses their harness while climbing?
Mike..Summit Treestands Inc. Decatur Alabama 256 353-0634, ask to speak to Karen or www. summitstands.com.
But like I'd said you can make it yourself and much cheaper.
I've used a 1/2 black polypropylene rope, the breaking strength was I think 5000 lbs, I picked it up at Home Depot and I tied the prusic knot myself--it's quite simple.
I wish if I could find a demo of the knot, I'll keep checking--if I do I'll post a link to it.
