The Sunny has been redesigned for lighter weight and better seating. Using Lite-Pack material on the interior where abrasion resistance is not critical, and Nitrylon on the exterior, the new Sunny is able to save 12% off the weight of the earlier model. It also packs smaller and the Lite-Pack material is much more comfortable to sit against. The new Sunny also features much improved back support for the seats with D-ring attachments at the side tubes.
