Proper school rucksacks.We have been through three with the weight that goes into them.My dd is developing a strong back.
Agree re the rucksacks! We're on bag number 4! The £28 Adidas one was taken back for a refund last week when it lasted less than 2 months.
There is a lot to be said for a 'proper' school rucksack. DS carts around a tonne of books in his bag, mistreats it on a regular basis and it is still going strong after 3.5 years (although looking a bit worse for wear) - for the initial outlay of just under £30! Most importantly, he does not complain of back or shoulder pains. It may not be quite as 'cool' looking as a sports branded one, but it has lots of pockets, decent, properly shaped shoulder straps and a padded back.
I asked our school shop where they get them from and they said they were made by Marathon, who apparently specialise in school bags. I took the liberty of sending to both of you a link showing exactly the same school rucksack as DS uses (but without a school logo), in case it may be useful. I promise I have no vested interests in the company who make them.
