There are many trunk bags available but we like this one for the following reasons:
- Four velcro straps quickly secure bag to rack without the straps going between rack and tire.
- Has reflective thermal lining to keep items cool or warm.
- 13 1/2 x 7 x 6
- Carry handle
- Soft sides can be pressed down if backrest needs to be lowered for shorter people.
- External rear pocket.
- Great for holding rack batteries.
