The missing link in our Nimbus lineup! The Meridian is a top loader with a floating lid/fanny pack and a single vertical zipper front access panel. It was specifically designed to withstand the rigors of the 10,000 miles of hiking our extreme pack tester Justin Lichter endured in 2006. "Trauma", as he is known as on the trail, started November 3rd 2005 and completed over 10,000 miles 356 days later (yes 356 days). We utilized the newly released RiRi water resistant tooth zippers for the fanny pack lid and the front access panel because they offer superior durability and water resistance to any other zipper we have seen. Reflective material on the daisy chains and on the shoulder straps insured Trauma would be seen when road hiking at night, they also make it easier to locate the pack in the dark. For slack packing strip off the lid and use it as a fanny pack. Built with the same frame and harness as our award winning Nimbus Ozone the Meridian pack offers the rare combination of durability, convenience, versatility, and comfort in an ultralight trail pack.
