Sets up in under a minute and retails around $2,000 (only available on Kickstarter currently). I dig how you can sleep 3 adults in a what amounts to a double wide traditional ski car top carrier. Aerodynamic while you cover ground and spacious when you lay your head down, powerful combo for the ski bum zipping around chasing powder on a strict budget. For more info go HERE.
Best believe it fits on a Subura:
