I'm 6'2". I'm tired of tearing up my shins on single track bushes, cactus, and thorny mesquite (the worst). I've been riding mountain bikes since I lived in Marin County in the early 80s and have never messed up my knees. I'm looking for budget friendly adult shin guards with a hard shell, preferably black. I've looked at soccer shin guards because they're a lot cheaper. Any recommendations?
