The best holdall on the market. I love this bag!
I have had it for about 6 years and it's as good as new. I use it 5 days a week to take to the gym and I often use it as hand luggage when I travel.
It has three internal mesh pockets, one at each end and one in the hood, and a detachable wet/dry bag to keep footwear/dirty kit/wet towels etc separate from your other belongings.
It's water resistant so it is great when it rains. It looks super-sylyish and I get loads of comments on it.
The only time I travel with a different bag is when I am taking a lot of camera gear (in which case I use a 20l rucksack by Peak Design) or a suit (in which case I use a hard case by Rimowa).
It costs £149 and you can buy it at:
