Help! Robust sports bag needed for year 7 boys

[Zed4]

Can any-one recommend a good sports bag for my twin boys in year 7. They have sport three times a week and regularly need a large sports type bag to take their kit and school books . We have bought approx 6 bags in the last 2 terms some of which have only lasted a week or two before they break -zips break, seams inside pockets go and just today a shoulder strap broke at the buckle. We have been buying from Sports Direct and so far tried Slazenger, Head, and Everlast. Any-one recommend any other stockists/brands?

Surfdome has hundreds of bags. Lots of detail about size as well.

We have some nike bags that have lasted 5 x a week sports with my boys

Thanks for the tips - off shopping now!

If you're still looking, ds's Jeep rucksack which I bought from Matalan for about £20 is going strong. He's has it a few years but must admit the first months of secondary have been harder in it. I'll look out for another when the time comes though.

SIL brought DS a good quality small Karrimor one recently which looks a lot more robust than the one he had that lasted only one term. Hoping this one will last at least a year
