Ideal for overnight backpacking trips the Osprey Ace 50 is specially designed to accommodate younger outdoor enthusiasts ages 11-16. With an ultra-adjustable harness and hipbelt the Ace 50 is able to grow along with its wearer over the course of years as well.

Employing ridge molded foam and built-in air channels the Ace 50's AirScape backpanel provides flexible support and breathability to combat heat build-up between the wearer’s back and the pack body. A lightweight aluminum frame and an HDPE framesheet effectively distribute weight and deliver supportive stability. The one-size-fits-all Ace 50 is actually anything but; taking into consideration that wide variety of shapes and sizes that youth backpackers between the ages of 11 and 16 tend to come in (and accounting for their growth over time as well) the Ace 50’s upper backpanel and harness slide up and down to fit individuals with torso lengths between 13” and 18”.

The hipbelt and harness straps are padded covered in mesh and perforated to keep weight to a minimum. The Fit-on-the-Fly adjustable hipbelt also is designed to accommodate wearers of various shapes and sizes. An adjustable sternum strap further aids in stability and enhances fit. Side compression straps allow kids to cinch down the Ace 50 to keep contents safely in place and aid in load control.

The storage capacity of the Ace 50 is an impressive 3051 cubic inches. NOTE: Body weight of the youth wearer needs to be taken into consideration so Osprey does not state a specific load range for the Ace 50; children and youth should not carry more than 15-20% of their body total weight.

The top-loading packbag in the Ace 50 is accessed beneath a removable floating top lid that incorporates a zippered compartment for gear storage. A zipper on the front of the pack grants access to a lower sleeping bag compartment with a divider and sleeping pad straps are incorporated on the lower exterior. Stretch woven pockets on the front and sides of the Ace 50 offer additional organizational options and keep gear and extra layers close at hand. Convenient zippered pockets on the hipbelt offer quick-and-easy access to other gear and essentials.

Other features found on the Ace 50 include an adjustable ice tool or fishing rod loop daisy chain attachment points and an integrated raincover to protect the pack from the elements. A lined exterior compartment makes the Ace 50 hydration compatible and enables easy refills of a hydration reservoir (sold separately) without having to access the interior of the pack.

The Osprey Ace 50 Youth backpack weighs in at 2 pounds 15 ounces when empty.
