Daylite 30-Liter Duffle Bag

If you want a carryon that uses all the capacity of big bags and no weight limits that many transatlantic flights offer, this is the one. I've taken mine on three 2 week horseback riding vacations, I can fit my helmet, boots, chaps, water shoes, 3 sets of jodhpurs, 2 sets of jeans, waterproofs, swimwear, big steal bottle, tech and enough tops and underwear, toiletries etc in this and the older version of the daylite 18l backpack for the trip. All I have to buy is sunscreen because of liquid rules, oh and I'm 6ft tall, so none of that gear is tiny either. It's also a great weekend/ gym bag, lightweight and easy to pack, but I bought it for the carryon capacity and it delivers it can be a sneeze over if you really bulge it out, but triple checking with a tape measure means it's never been an issue. I've not tried to take it on a strict European flight though.
