I bought this bag to replace my Lululemon gym/work bag which had a broken zipper and was annoying to carry and find things in. This bag fits SO much stuff (when organized well at least). I can easily fit gym clothes, sneakers, lunch, water bottle, iPad and some makeup/toiletries with room to spare. Very comfortable to wear, looks great and seems very durable so far. I have two Sidekicks from Poppy & Peonies which I love and continue to tell everyone I know about the company and awesome products.
