It has been Mystery Ranch's mission to create the best load carrying equipment in the world, they’ve set out to achieve the best fitting, most comfortable pack harnessing systems possible. Over the last few years, they spent countless hours measuring and fitting hundreds of different body types and logging the results to better understand how their customised fit interfaces with all different body types. The result has been a new sizing configuration that fits just about every human out there and unifies MYSTERY RANCH pack sizing across the board.
The key to a confortable pack load is a properly fitting backpack. Mystery Ranch have designed a more custom fit into their packs with simple sizing based off two measurements. To find the appropriate size waist and yoke for your pack, collect the following two measurements, then reference the sizing chart below.
1. Waist Circumference - Measure around your waist just above the top of your hip bones (roughly two fingers below your belly button).
2 Torso Length - Use a tailors tape or string and have a friend measure between the bony bump at the back of your neck (C7 vertebra) to the spot on your spine behind your belly button.

In Between Sizes?
If you are between sizes on the waist belt, we recommend you choose the smaller size. It is very important that the waist belt is able to securely tighten around your hips. If your waist belt is too big you will have a hard time getting the weight in your pack to transfer from your shoulders to your hips. If you are between sizes on the yoke or if your measurements fall outside standard sizing, please contact us.
