I love this thing! I bought it during the 20% off sale at REI a month ago so instead of $70 it was $56.

It has these fold-up panniers that I never thought I'd use and I LOVE THEM! You can take jackets, flip-flops, books, food, etc. I put my cable lock in there sometimes, shoes, you-name-it.

It's REI so if it ever breaks I can return it for a new one but so far it's sturdy as heck. Has a built-in rain cover as well. Sometimes I don't use either pannier and just throw my tools, pump, spare tubes, wallet, camera in the trunk and ride away. Don't need a cycling jersey on my short trips because there's nothing to put in the back pockets - no seat pack needed either.

I don't see a lot on this trunk bag but personally I have really enjoyed mine.
