These covers are the best ever hands down! They stay on with strong Velcro and keep your irons from getting beat to death against each other, especially in a cart. I like them so much I have the black ones also, for my other set of irons. I have used these for over a year with no issues and they are still look brand new after 100+ rounds a year. When playing I leave my sand wedge cover in the cart but it is the only one bare so no issues clanging. I did a lot of research and I definitely made the right choice. I use Callaway Apex 21 irons in one bag and Callaway Maverik irons in the other bag and they fit perfect!!! Don’t hesitate to buy these covers, they will save your irons!!!
