We built the Shuttle bag using completely waterproof materials and with a completely separate top entry/roll closure, wet compartment - Stash your soaking wetsuit, rain jacket, dirty shoes & clothes and don't worry about wrecking the rest of your clothes or gear that are stored in the backside main compartment of the bag - Easily access this dry storage through the back compartment that fully unzips the back panel and fully expands to lay flat so you can organize like a suitcase. Keep your gear tight and right for the trip with this roomy main compartment with a mesh organizer for your toiletries or devices and chargers. The Shuttle also features a padded laptop compartment that is quickly and easily accessible from the top exterior of the bag and sealed off with a YKK Aquaguard Zipper. Stash your phone, passport, and keys in the side zippered compartment for convenient access.
