After ordering a Berghaus Optimus 40 a few years ago & remembering the good service /price, I decided to use F&T again as my friend wanted one. I couldn't find a Berghaus so opted for a Karrimor Transit 40. I was very confident ordering this because of the quality of past & present Karrimor backpacks. The one & only negative on the Berghaus was that if used as a backpack after using as a trolley, then the wet/dirty wheels left marks on your jacket. This has been solved on the Karrimor with a drop-down flap that covers the wheels. I can't imagine a more perfect pack for my needs. It's main use is carry-on hand luggage but also for shopping.
