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:

• 50-65lbs is about the max recommend carrying capacity. 
• 35-40lbs will be comfortable for long days on the trail. 
• 30lbs and under will feel like there is almost nothing in the pack at all. 

These packs are made completely out of Ultra400X. 

The accent color is made out of EPX200 which comes in various colors. Black Ultra400X can also be selected for extra abrasion resistance. 

The stretchy pad sleeve is made out of very durable Venom Mesh which is reinforced with UHMWPE fibers. 

Our new packs are 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 400d Ultra PE (similar to Dyneema) is about 20% lighter, with twice the abrasion resistance of other 400d UPE fabrics. With or without a liner, it is the ultimate high-modulus pack fabric and the most durable fabric we have tested for its weight. 

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.

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. 

Torso Sizing:

This pack currently comes in three different torso sizes, each of which is adjustable by 3". These listed sizes are the actual torso sizes that the pack can be set to. We recommend going with a torso size that is as close as possible to your measured torso length, but being within .5"-1" of that size will typically work for someone. If you are on the upper end of a torso size we recommend sizing up.

• Sm 15"-16"-17"
• Med 17"-18"-19"
• Lg 19"-20"-21"

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:

26" belt for waist sizes 26-30"

30" belt for waist sizes 30-34"

34" belt for waist sizes 34" and up

We currently offer three hip belt sizes which are 26",  30" and 34". 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.

If you want a lighter pack/hip belt you can always size down on the belt. This will however make hip belt pockets less accessible while wearing the pack. 

Frame Size:

The Big Wild pack comes with our taller load hauling frame which has very effective load lifters. The load lifters can pull all of the weight off of your shoulders and put it onto your hips. This gives you the ability to control exactly how much weight is carried on your shoulders or your hips at all times.
