Any recommendations for a bag to carry hand weights to class?

I've searched and all I find are bags that you're meant to load up with weights and wear to make exercise harder. I want something (probably a back pack) that I can carry my 2 x 3kg weights to class - bonus points if I can get my mat, water bottle and phone in there as well. or maybe I need two different bags? Anyway, my normal backpack is not going to survive much longer if I keep using it. I need a bag made to withstand the weight. Any ideas please?

For that sort of weight and long lasting I might look at a camping day sack about 30l. They'll be reinforced enough to take a small tent etc and will have water bottle pockets outside and probably elastsics for tent/sleeping bag / walking pole on the outside that you could put a mat

Something from Osprey. Their bags are amazing.

A huge tote from the contents bag would work

Thanks, good suggestions.
