Review: Roomy and easy to access - Needed a new bag because I had to put a light and my varia sensor under my seat. This bag holds tube, levers, pressure gauge, CO2 and adapter + sunscreen stick, a couple small snacks, inhaler, extra drink powder, Id+money+keys, echo buds case. And there's still some room. Love the top zipper so nothing falls out, and you can open just a little too just get what you need. Doesn't bother my legs while riding, doesn't slip around. It's sturdy and looks slick.

Love this top tube bag, it is large enough for my iPhone and other things like snacks.

### ⭐⭐⭐⭐ easy access to storage
*by U***8 on April 21, 2025*

Very nice bag for the price. I have taken it on many 300+ mile bike-packing trips and it is still holding up. I like the zipper right down the middle, makes it easy to access whatever you store in it. I would give it 5 stars but it tends to roll over from one side to another, making me hit it with my knees. Overall I would recommend.
