What a great thread! I have a water-proof Pacific Crest Trail jacket that is impervious to thorns that I got at a thrift store, and I have a heavy denim jacket that also works well when it's not so cold. I wore a pair of stretch jeans this week when pruning, and had to throw them in the trash later, they were so torn up from the rose thorns. But I've never had trouble with my regular denim jeans so far. I use long goat skin leather gloves that have been very protective.
