Great size for adults and children. I like that it has a little pouch inside to keep the moisture and smell at bay. The bag has a really good zipper that is the kind that doesn't snag the fabric or catch on it.
I feel like you can pack a lot into this and I believe that it is washable. I purchased this as a backup lunch box but it has manifested into the new daily lunch bag because "it's cool mom"!
The inside has extra poket and it is easy to carry as well.
