Onda is a Boulder based spin off brand of a company that designs hard shell spare tire covers for SUVs and automotive arm rests. They launched at Interbike 2011 with their bike trunks and trailers. Very attractive.
The trunks lock for somewhat secure storage of your goodies, and also have a quick release so you can strap the trunk to your back to carry into the store or class if you want.
Trailers are lockable hard shell as well. In spite of the ABS contruction, they weigh only about a pound more than similar capacity soft trailers.
