I recently replaced my straps with one inch strapping from a local outdoor store. I assumed it would be strong enough but after all this talk about straps breaking etc. I decided to call them and check. They informed me that the straps were "not strength rated" which made me a bit uneasy.

Yesterday I called a local EMS (Eastern Mountain Sports) store which carries a 1" strap rated at over 4000 lbs. but it is made out of nylon. My understanding is that nylon stretches more than polyester. My question is....how much stretch can I expect and does it stretch only once. I don't want to deal with stretch each time I hang the hammock.

I plan on heading over to EMS later today so a quick response would be appreciated.

Thanks, Miguel
