I don't know about those, but out here we have joshua trees
When I get called to cut one, I wear full welding leathers, leather gauntlets, balaclava, goggles, and Stihl helmet rig w/ faceshield.
Sounds like pretty cruddy stuff. I hate thorns. If anyone else out there has welding leathers, try wearing them next time you've got a thorny beast to work on. They're hot as hades but work pretty good for puncture protection.
