I have bought a backpack while it was on sale which is called 70L and assumed it was the right size because the 70 written on it. I have since received all the paperwork from Topdeck and I'm not sure it is the correct size. Am I able to bring it? I have paid a lot of money for the backpack and don't think I can return it because it was a sale.
Sizing is according to the backpacks website: L 79cm x W 37cm x H 37cm.
