I bought these so I could set up pickup games for my high school age son and I, he still has his senior year to go and one more year of playing football at his school.So far we've had one game that lasted about three hours.We had eleven people all together, five varsity players from his school and then six adults.The flags survived the game just fine except one flag got ripped off the belt but that was because one of the kids tied it incorrect and it couldn't come off.You're just supposed to use the little clip to attach the flags around your waist but he tied it so it couldn't come off without ripping it.It's not that the flags rip easy it's that people get a kung fu when playing, the first attempt to pull his flag didn't work so about two steps later someone else got their hand on it and that flag didn't stand a chance:-)I played flag football for years as a young adult in city leagues and tournaments all over my state, so I've used every kind of flag made.These are good quality flags, about as good as they get.There's only one other kind I know of that are better, they're an exact replica as far as use they're just made a little tougher.But they cost a lot more.These flags are just fine and will last a long time if used and stored properly, I'll be buying more as needed of this same brand and type.I use to run a tournament for flag football where I live, I did it for seven yrs.As long as flags are used properly these particular kind shouldn't break at all.Storage is also important, if they get wet and don't get an opportunity to dry the water damage can weaken the cotton and then they'll break easy.I recommend these flags, they're good quality and affordable.Proper use and storage and they'll last for many many games.
