Light and Comfortable
I use this weekly to put swim kit in and then run to the swimming pool, my youngest lad follows behind on his bike. We just chuck his kit and the bike lock and off we go. Lightweight and comfortable to run with a couple of miles.

Lightweight rucksack
This bag is everything it says it is. Great quality, very pleased. Needed a lighter easier way of carrying my cold water swimming gear. Had previously been using the Red tote bag, so knew quality would be good.
