This is worth the money. I have an average sized mat and I can fit in my towels and Pilates ball with no problem. It could even fit a much larger mat without blinking twice.
The material is nice and thick with a few pockets to fit various things like gym passes etc. It’s easy to carry with a nice thick strap, though it’s not waterproof. It’s lovely and colourful and it doesn’t feel as cheap as the price.
