Great for snacks

I use the xxs one for packing snacks on the go. Works great for that purpose and the fact that is weather resistant was a defining factor in my buying decision for this use case.

very lightweight indeed

I bought one white bag 3 weeks ago ( before they sold out so fast). its volume is bigger than expected, very lightweight indeed. Very happy with it.
