Granite Gear Nimbus Ozone Internal Frame Backpack

Product Highlights

Coupling the award-winning ultralight design of the Vapor Trail with a molded framesheet, the Granite Gear Nimbus Ozone offers greater load-carrying capacity while still weighing less than you'd expect of a heavy-hauler. An excellent balance of weight and performance, the Nimbus Ozone comfortably hauls loads of up to 40 pounds while weighing in at right around 3 pounds.

The Nimbus Ozone is available in two torso sizes. The packbag on the Regular torso offers 3800 cubic inches of storage capacity and the Short torso size offers 3400 cubic inches. Lending extreme versatility, a well-designed external compression strap system allows you to securely cinch down gear. The Nimbus Ozone does not have a traditional lid. An extendible spindrift collar protects the interior of the Nimbus Ozone's large single compartment. The collar rolls down and cinches closed with two overlapping, integrated buckle straps that accommodate loads of varying sizes.

Made of a reinforced composite material, the Nimbus Ozone's Topoflex framesheet is ready-made for heavy hauling. The streamlined, contoured framesheet balances rigid support with flexible response, allowing the Nimbus Ozone to move with you while keeping your load balanced and secure. The height of the framesheet can be adjusted to account for varying torso lengths. The lumbar portion of the framesheet functions like a shock-absorbing spring and enhances comfort and performance. A pivoting, cushioned hipbelt helps to further balance the weight of the pack without limiting mobility.

Made of lightweight, durable 210d Cordura and 70d Cordura/Rip-Stop fabrics, the Nimbus Ozone offers rugged durability without weighing you down and a fully padded backpanel provides a layer of cushioning and comfort. Adjustable padded shoulder straps, an adjustable sternum strap and load-lifter straps combine to optimize fit.

To guarantee that the Nimbus Ozone fits like a glove, Granite Gear offers swappable gender-specific hipbelts and shoulder harnesses. The S hipbelt fits waists ranging from 26”-30”, the M hipbelt fits waists ranging from 30”-34” and the L hipbelt fits waists ranging from 34”-38”. The appropriate shoulder harness size is based on the girth measurement of your chest. The S harness fits chest sizes ranging from 27”-34”, the M harness fits chest sizes ranging from 34”-40”, the L harness fits chest sizes ranging from 40”-46” and the XL harness fits chest sizes ranging from 46”-52”.

Two large elastic pockets on either side of the Nimbus Ozone keep water bottles or other gear close at hand. A built-in tube exit port and a narrow lined internal pocket that accommodates most hydration bladders (not included) make the Nimbus Ozone hydration compatible. The bladder pocket includes a convenient bungee cord compression system so reservoirs remain securely in place. The external compression system and reflective daisy-chain shoulder attachment points provide numerous places to lash additional gear to the outside of the Nimbus Ozone.

The Granite Gear Nimbus Ozone is available in Regular (18"-22") and Short (14"-18") torso lengths and your choice of Brick or Lapis color options.
