I just returned my Yakima Sky Box 16 after it popped open for the second time in a few years. Coincidently, this occurred while crossing bridges both times and we lost lots of gear both times. Also, the lid popped off the hinges after while packing it during a blizzard at Alpine Meadows. Yakima has not even given me the courtesy of a response from so-called customer service.
On to Thule.
