No replacements are available as Titleist does not sell bag parts, only complete bags. Washing machine might be a good idea but personally, I think I would hand-wash in the tub with dish soap just to control the process a little better than trusting my washing machine. I usually snap off the straps when riding in a cart just the avoid having them hanging out and getting dirty or snagging onto something. I have also used "seat belt pads" sold at the auto parts store as a way to protect, add padding, and take on the daily wear of the straps. Easy on and off with Velcro. Hope this helps.

Might suggest looking on eBay. They have Wool protectors that fit on the straps. I have used them in the past, when I was a walker, and they worked well at protecting my shirts. Washable and run around $20 each.

Probably the exact same thing I got at the auto parts store for about half that price. :)

Even better......
