Yup, Spinntex is derived from sailcloth, ie spinnaker (hence the name), and uses polyester (lower stretch than nylon, especially when wet) instead of standard nylon.
What's strange is, I had assumed the Mountain Laurel Designs was using the same stuff that Thru-Hiker sells, but MLD has it listed as nylon instead of poly.
