In our testing we have found the max weight capacity for this pack to be about 60-65lbs.  The pack can handle much  more weight without failing, but it becomes less comfortable when pushed past 65lbs or so. 

Comfort ratings:

60-65lbs max load.

45-55lbs comfortable for all day hiking. 

35-40lbs very comfortable.

30lbs and less, you'll be floating down the trail. 

Our new packs are made using a more environmentally friendly line of laminated fabrics. 

The woven fabric is 100% Repreve recycled polyester. The proprietary Challenge RUV recycled film backing is 100% recycled and 97% UV Resistant. Every yard of ECOPAK™ saves over one pound of CO2, compared to Nylon pack fabric. ECOPAK™ contains no harmful TPU, PVC, DWR or other coatings. CO2 emissions from manufacturing our recycled polyester are: 50% lower than Nylon 38% lower than virgin filmcomparable to organic cotton

The main body of these packs is made out of EPX200. A 4ply laminated fabric consisting of a 200D polyester face fabric, a 45* X ply, a waterproof film, and finally a 70D ripstop backing to protect the waterproof film and to improve seam strength.  It has a finished weight of 5.9oz per sq yd and is completely waterproof.  

The bottom and stress points are made out of EPX400 which is a 4ply laminated fabric consisting of a 400D polyester face fabric, a 45* X ply, a waterproof film, and finally a 70D ripstop backing to protect the waterproof film and to improve seam strength. It has a finished weight of 8.9oz per sq yd and is completely waterproof. 

Our shoulder straps and hip belt wings are made out of 1/2" thick evazote foams. These are the most resilient and longest lasting foams that we can find. They will give you many years of use without flattening out. 

Shoulder straps and hip belt wings are made out of a 420D Robic nylon for maximum tear resistance. 

Torso Sizing:

We have three different torso sizes, Sm 15-18", Med 18-20", and Lg 20-22". 

If you are on the upper end of a torso size we recommend sizing up.

The Big Wild packs come with tall frame sizes to help with carrying heavier loads. The large frame is 26", the med is 24" and the small is 22". 

To measure your torso size you will need to measure from your C7 Vertebrae down to your iliac crest/hip shelf. To get the most accurate measurement, it is best to have someone else measure your back with a flexible measuring tape. The measurement will most likely fall somewhere within our sizing chart. If you do not fall somewhere in our sizing chart shoot us an email and we can discuss custom torso sizing.

​

The goal for packs with a padded hip belt is to get the belt to ride so that the center line is close to riding on your hip bones. That way you will get the best load transfer to your hips, removing a bulk of the load from your shoulders.

Hip Belt Sizing:

We currently offer five hip belt sizes which are 26", 28", 30", 34", and 38". Each measurement is referring to the amount of padding that the belt will have. Each hip belt will come with enough adjustable webbing to fit up to about a 50" waist or so.  

​

To find your correct hip belt size you will need to measure the circumference around your hips rather than your waist size. This measurement should be at least 4" larger than the padded portion of the hip belt. 

​

When in doubt size down, as you do not want the belt to be too large. If the hip belt is too big, you will not be able to tighten the belt down all the way making for poor load transfer to your hips.

Our packs are hand-made by us right here in Michigan and are constructed using the finest materials and the best construction methods. These packs are ready to handle anything you can throw at them, and will give you thousands of miles of use.

All of the main body seams on our packs are quadruple stitched and flat felled. All stress points are reinforced and bar tacked. The flat felled seams make for easy seam sealing on the inside of the pack. 

Our packs are very water resistant and are made out of completely waterproof fabric. The inner seams however are not seam sealed, and can leak a bit in prolonged rain. We recommend seam sealing if you want a completely waterproof pack.
