I purchased the webbing at REI. I picked up some continuous long fiber thread at a local fabric store. This thread was meant for sewing outdoor "stuff". There was one rack of thread labeled as for that purpose.
Two 6 foot straps for $9+ shipped seems like a good price. Thanks for the tip.
Thanks for the reply. I will look into the tubular webbing. Thanks for all of hte helpful information. Great group of people.
After I got sick of the slap straps, I bought some of the REI tubular webbing. It was inexpensive and worked good, but I highly recommend that you use webbing from Dutch or one of the other awesome vendors you can find on this site. The savings in weight and packed sized is ridiculous.
I switched my ENO over to whoopies and a Dutch buckle setup and it's a thing of beauty and simplicity.
Check out the Dutch buckle-whoopie-webbing combo for a setup that will have you hanging in under a minute.
