I don't have sleeve, but I do have a decent sized one on the side of my right arm. One time I took a fast-paced dive on my mountain bike and landed hard on my right side and slid quite a long ways across a series of thorn brush. I was cut up, bleeding all over the place, but I kept riding and made it back to the car. Ultimately my tat was fine once the damaged skin healed. Any serious stuff can be touched up, but you have to realize - tattoos go ultra deep in the skin, and most wrecks won't go nearly deep enough to damage tattoos. I know a guy who had an insane wipeout on his motorcycle and did far more damage than what's typical on any kind of bicycle, and his healed up fine. Took a while, but they healed without altering the design.
