The ABSOLUTE handiest panniers I have. And, at a great price for the next 3 days. http://www.nashbar.com/webapp/wcs/st...firstname.lastname@example.org Less than $10.
I have the Performance brand, but I think they are the same.
You can drop a FULL paper grocery sack in each side, and large enough for most boxes. Fold up flat when not in use carrying things, and without a doubt, the handiest for just gettin things.
I also stack another plastic grocery bag on top of the first one, and hang two more plastic bags over my trunk bag. Thes things carry a lot of stuff, whether it's clothes, picnic goods, or groceries.
