Envirosax is a company that sells reusable bags. These bags are very compact and roll up to fit into very small places, They can hold up to 40 pounds. These bags are great to place into your purse of diaper bag even car for when your out. I use mine for going to the store or even putting clothes in if, I'm going to sleep over. Using these bags helps the environment by not using plastic and using this reusable bags. I also really enjoyed my print on my bag.
