Durability
The Shuttle 100 is wrapped in an incredibly durable 420HD Nylon Packcloth shell with 1680D Ballistic Nylon covering high-abrasion areas. The structural frame is made of rigid and lightweight 6061 aluminum with injection moulded ABS polymer and has not shown any sign of flex or fatigue. The ABS polymer is exposed on the undercarriage with Osprey’s HighRoad chassis, to protect the nylon shell fabric from where the most impact and abrasions occur. Small winglets extend out from the front of the bag and are part of the compression strap system to cocoon the bag and help protect the durable  zippers.

Weight
At only 8.1 pounds, the Shuttle 100 is the second lightest bag in the test but still one of the largest. It provides the second most room (753 sq in) per pound making it one of the most efficiently built bag in the test. 

Maneuverability
Osprey has gone above and beyond in making the Shuttle 100 easy to move around. With handles on all four sides plus the compression straps that reach across the front of the bag which can be grabbed if needed, there’s always somewhere to hold. Large wheels on a solid frame allowed this bag to power over the roughest surfaces. At 14” this is the thickest bag tested and the center of gravity can be higher than ideal, depending on how it’s packed. Testers found with the right bump along the way the bag would tip over. 

Features
Most of the Shuttle 100’s features come in the form of organization & structure. To make the bag more comfortable to lift and carry, thick foam pads have been added to the inside of the handles. Compression straps (plus the winglets mentioned in “durability”) help secure the load and protect the zippers and the bag. There are three small loops at the top of the bag that can be used to hold a dynamic or static cordlet for hanging gear as well a hidden strap and buckle to connect a companion bag to create a bag train or to hang a briefcase or purse. It also has lockable zippers as well as an ID pocket.

Organization/Packability
Without being overwhelming, the Shuttle 100 is loaded with pockets. Each of the pockets are subtle enough to remain unnoticed until you need them. The main panel access compartment zips wide open and there are three large internal mesh zippered pockets built into the wings and the panel top. The divider between the main compartment and the lower zipper compartment is flexible and can adjust as needed, say as clean clothes become dirty along the way and then can be stored separately in the lower compartment. At the very top is small pocket configured the same way as the lower pocket but it also has a small mesh zippered pocket. When packing, the traveller can use all of these pockets or just the main compartment without compromising the capacity of the bag. Plus, on the back of the bag Osprey has made use of the gap between the frame and the back of the bag by adding a zipper and a pocket. This pocket is large enough to hold a small garment bag and it also has a small zippered mesh pocket. Sitting on the outside of this pocket is another Velcro pocket big enough for a magazine and the ID sleeve is on the inside of the flap. The only complaint? One tester wished the top load panel unzipped right down to the base of the bag.
