Yes, I can think of a variant that, if valid and available, is ideal in an outdoor situation.
My grandfather told a story of cutting his finger deeply with a carving knife as a kid; his mother went down to the cellar, grabbed a handful of spiderwebs out of the corners, and wrapped it in that, and then a rag over top, and tied it on there. It stopped the bleeding, and three days later, the cut was healed, he had only a slight scar. He felt that these days the cut would merit about a half-dozen stitches.
So if you're outdoors and can find some (or enough) spider webs ... maybe give it a try? For science?
