Kids Duffle Bags!
They have 2 pockets on the outside, and one zipper pocket on the inside.
Approx 35cm long, 15cm wide, 20cm high, they may seem small but they hold a lot! I easily fit a toiletry bag, 2 pairs of pjs, and 6 days worth of socks, Undies, long sleeve tops and leggings of kids clothing!
My niece absolutely loves her bluey duffle bag, she takes it everywhere with her
