1) The colors: (I like the orange and yellow since they're bright and I feel like I won't leave the house forgetting them. They're also unisex so my husband now has a bag he feels comfortable carrying. win-win.
2) The sizes: the medium holds everything I need for two kids! Plus my 15" laptop and two H20 bottles. My small bag fits my pump perfectly.
Each medium bag is 42cm x 30cm x 12cm.
Each small bag is 33cm x 23.5cm x 9.6cm.
3) The fabric: water proof is now a necessity for me!
