When it first arrived we thought it looked too small to hold much, but once we started to fill it, we realized how roomy it really was. We fit heavy sweatshirts, gloves, rain gear, sunscreen, water and more. Loved the flat strap on top to slide maps into for easy access while riding. The protective bag held up well in light rain, but don't count on it to keep things dry in heavy rain. However, it did stay on while riding on the highway.
Overall would recommend it.
