The next project on my cutting table is a clone of my beloved but well used Gossamer Gear Mariposa plus. I've shortlisted some swanky materials for the main body it but wondered if I'd missed any that were available? Does anyone have any experience with any of these fabrics? The Dyneema/Nylon looks like the ULA packs and X-Pac is familiar.
