Chosen your pack but not sure which size will fit you best? PackSizer 2.0 is a new innovative pack sizing app which uses the camera on your device to match your torso length to the right pack size across Osprey’s entire pack range.

In just 3 simple steps PackSizer 2.0 will use a full-length photo of yourself to provide you with your pack size. There is also an option to size yourself manually if you wish.

Once you have received your pack size you can browse all Osprey packs which will fit you. You can filter packs by activity, find out more about individual packs and go through to the website to buy your chosen pack.

PackSizer 2.0 also features a resources centre where you can discover guides to help you choose the right pack and learn how to prepare for your adventures.

A huge improvement

This new version works so much better. It was quick and efficient and I ended up with a perfect backpack. It’s almost as good as having an actual expert showing you how to fit a pack!

The app gave me accurate sizing information, along with all the packs that would be suitable for me. Really helpful, and easy to use.
