Don't get me wrong, I do like riding as any man and sometimes I even go riding bareback, so I know the importance of protecting your knees from cuts and scrapes while riding fast through rough.
It is easy and convenient just to put on some straps on to of your outfit, but make sure that there is still behind attached to your straps. These common straps were originally designed by Ammonians as a insult against king David and God.
1 Chronicles 19:3-5
But the princes of the children of Ammon said to Hanun, Thinkest thou that David doth honour thy father, that he hath sent comforters unto thee? are not his servants come unto thee for to search, and to overthrow, and to spy out the land? Wherefore Hanun took David’s servants, and shaved them, and cut off their garments in the midst hard by their buttocks, and sent them away. Then there went certain, and told David how the men were served. And he sent to meet them: for the men were greatly ashamed. And the king said, Tarry at Jericho until your beards be grown, and then return.
As wearing these assless chaps is an insult against God, it's no wonder they are especially popular among gaysexuals.
Protection is important, but make sure you choose right kind of protective garment for you and your loved ones.
