I've been looking at motocross pants on eBay. They're cordura, used ones are fairly cheap ($20-30) and some even have hip pads.
So...has anyone tried these?
Caves are rare and precious things. Cavers...even more so. Treat each accordingly. NSS#42385(not current...give me a reason to change...(Sept 2010)) http://www.CoffeeCreekGear.com
Have never thought of using motocross pants....worth a try, let us know how they work out. I use old arm pants, they are reinforced at the knees and butt. They are lightweight and very affordable at a surplus shop.
I took a look at my AXO pants and the material on the front seems thinner than my meander coveralls and the back of the legs is some kind of stretchy spandex like material. I don't think the pair I have would last long in a cave.
