I want to buy a large holdall for my teenage son who has a school trip to Iceland and potentially other trips coming up. I want it to be good enough quality that it will last several years, but don't want to get sucked in to paying for designer branding etc. I want the sort that can be pulled behind you on wheels or carried. It should be holdall shaped rather than a suitcase.
Any recommendations? It's going to be a Christmas present, and I'm currently budgeting for between £50 and £100.
