Great bag. Perfect size for when im on the motorcycle. Not too big not too small. I ordered the large for the sizing. fits a hoodie, bottle of soda, thermos. I like it.

**UpDate**  Been using the bag for almost 8 weeks which is almost 2  months. The inner liner has torn. I use the bag everyday. Inside material not very sturdy or durable. Also the way the pockets are made you end up feeling like there is no room when you use the main large pocket and the 2 smaller pockets in the front. Should have been made sturdier and not so flimsy on the inside. I guess you get what you pay for. Do more research and get something worth the $$ that will lasat longer. The last thing I want to do is purchase another bag.
