HexArmor ThornArmor 3092 Cactus/Thorn Gloves
These are the only cactus gloves I've found (after trying many!) that will actually protect from Trichocereus spines!
I absolutely love them, I use them daily, and I'm proud to offer them on this site :)
Reenforced with Kevlar and still comfortable to use, nothing beats these. Just don't go around slapping cactus, and you'll be fine ;)
