Great product and smart invented

The tailfin is a great substitute for a normal seat bag. It’s very stable, easy to pack and unpack. The space is enorm and the quick release system is sublime.
Great advantage for small frames, like the one of my partner. She has a small and the normal seat bag has no to less space with the rear wheel.

Could be more adjustable for small frames

Hi Dave, thanks very much for completing a review for us. We settled on the additional 50mm length for the AeroPack Extender as it allows for the same max weight to be carried in the bags (any longer and the max weight would need to be reduced). I’ve followed up with a separate email with some tips on how to get the most out of the AeroPack though. All the best, Dan

Super simple and super lush

Before it arrived I was a bit worried about having to assemble the rack/bag but when it arrived it was proper simples.

The bag is big and already survived a lot of mud and rain whilst protecting my luggage.

We bought up all of the possible connecters so that we can move it from bike to bike and really do love it.
