Size Selection and Fitting Instructions
How do I know if an Exo Mtn Gear pack will fit me?
Our K2 Frame features an adjustable harness to accommodate a variety of body shapes and sizes. The most important sizing consideration is your torso length, which can be easily measured — this video shows how. Our frame will perform best for individuals that have a torso length up to 21”. Our frame can still be used for those of you that have a longer torso length, such as 22”, but when loads get really heavy (above 50-60lbs), you will be carrying a larger portion of that weight on the shoulders, whereas we typically like to have nearly all of the weight distributed to the hips. The other sizing consideration is selecting the proper waist belt size...
What size hipbelt should I choose?
Our waist belt sizes are Small for 29-33”, Medium for 34-36” and Large for 37” and up. To make it easy, we are listing those numbers based on pant sizes, not actual waist measurements.
If you are the borderline between two sizes (if you wear 33-34” pants, for example), we recommend going with the smaller waist belt. The danger with going up to the larger waist belt is that you will run out of room to cinch the waist belt tight enough — especially when loads get heavy. Additionally, most users that are border-line on size tend to be thinner at the end of a long, physically-demanding hunt.
If you do take an actual measurement at your iliac crest, then you can use the following sizing: Choose a Small waist belt if your actual waist measurement at the iliac crest is below 34.5”, a Medium if your actual measurement is 34.5-39”, or a Large if you are above 39”.
Do not worry about the clothing layers that you will be wearing with the pack, such as an insulated jacket, and think that you need to “size up” to accommodate for that bulk.

The Fitting Process
Before you begin to fit your pack, please make sure that you are not wearing a thick leather belt, or any other items that you wouldn’t wear while hiking or hunting with the pack in normal conditions.
Additionally, it is important to step through the fitting process with a load of 20-30lbs in the pack. You’ll also want a mirror handy, so that you can see how the pack is fitting you once it is in place.
Once you have some weight in the pack, loosen the adjustment straps (hipbelt, shoulder straps, sternum strap, and load lifters) and put the pack on your back. Now you’re ready to begin testing the fit…
- Center the hipbelt on your Iliac Crest — the center stitch line of belt should be roughly at the top of your Iliac Crest. Secure the buckle and snug up the belt. Do not be afraid to get the belt tight, which allows the majority of the weight to be carried on your hips and not on the shoulders.
- Vertically align sternum strap over sternum, secure the buckle, and gently snug it into place, setting the shoulder straps at a comfortable width
- Begin to tighten the shoulder straps until you start to feel the pack pull into your body
- Snug-up the load lifter straps, removing slack but not pulling past taught
- Standing tall and straight, evaluate the amount of gap between the shoulder straps and the top of your shoulders toward the rear. You should be able to slide your index and middle fingers between your shoulders and the strap, but should not be able to fit your hand in the gap
- If necessary, remove the pack and adjust the torso length to achieve the desired gaps. If the pack was riding too high and the shoulder gap was too large, bring the harness down; and vice versa.
- When adjusting the shoulder harness to make torso length adjustments, be sure to re-loosen all straps and repeat the process from the beginning to test the fit of the new setting
Those are the important steps in making sure that the pack is properly fitted to your body. As you continue to wear the pack and gain experience carrying different loads, you can continue to fine-tune the adjustments to achieve maximum comfort for your body’s shape.
