I just purchased a bag strap because the original one (that I have used a little over a year) was leaving a light black stain on my right shoulder. I first thought it was dirty, but washed the strap and it continued to happen. I basically ruined about five golf shirts (I should have quit earlier). The new strap is here and fine. I play a lot of golf, and carry all the time so i would guess I played 100-130 rounds with that strap before this started happening. I love the bag, probably my favorite in 50+ years of golf bags, but was really disappointed with the strap problem. (I will hit submit as Cheryl Byrd, but this is Rick, her husband) My email is rick.byrd@belmont.edu I am sending a photo (after washing the shirt).
