HapTim Multi-function Large Baby Diaper Bag BackpackStylish & Durable with Anti-Water Material (Dark Gray-5284)

I bought this bag because I have 3 nieces, ages 3, 6, and 7, that spend most of their summer with me. I plan events such as museum visits, splash pads, pool days, park visits, farm country, indoor discovery jungle gym, and much more. This backpack has not let me down. The 3 insulated pockets were a must for me. Since we do a lot of outdoor activities, and the summers are really hot where we live, 93-97 degrees. I like that their water bottles stay cold. I once left the backpack in my car for 3 or 4 hours in 95 degree weather, and found that although most of the ice had melted in their water bottles the water was still cold. I use the large front zippered area for all the food, water and snacks we need. I absolutely appreciate having a security pocket against my back. Where I put my phone and wallet that way i can stay focus on the kids while in crowded areas, and not worry about my valuables being stolen. I can fit so much in the large back zippered area. Change of Clothes for 3 kids, and shoes for 3. I have really enjoyed how versatile this back pack can be. I headed for a day at the lake yesterday only packing for me and it was perfect! Also at the lake it rained on the backpack and everything inside stayed dried! Yay! It looks well constructed and the material seems durable.
