Fabric Information

Ecopak™ fabric from Challenge Sailcloth is the first 100% recycled pack fabric in the world. It is durable, super lightweight, waterproof, made from 100% recycled polyester and one of the most awesome fabrics we have found.


Besides looking great, super abrasion resistance and being water proof, Ecopak™ is environmentally responsible:

  • The DWR is CO with no fluorocarbons
  • The adhesive contains no solvents or VOC's
  • Uses over 20 plastic bottles per yard, reduces CO2 emissions by over 1 lb./yd
  • Recyclable after use

We use a variety of Ecopak™ fabrics in our products. The denier of the fabric on our site is represented by 70, 200 and 400. The higher the number, the more heavy duty it is.

Bio-Based Dyneema® Composite Fabric (DCF) and formerly known as Cuban Fiber is a patented: high-strength, high-performance, non-woven, laminated and reinforced with Dyneema® fibers material. 


"Mass balance accounting is a well-known approach that has been designed to trace the flow of materials through a complex value chain. The mass balance approach provides a set of rules for how to allocate the bio-based content to different products to be able to claim and market the contents as 'bio'-based."

It is constructed from a thin sheet of ultra-high-molecular weight polyethylene that is layered between two sheets of polyester. 


DCF is known for its high-tensile strength where lower weight is desired. The fabric is lightweight, flexible and waterproof.  


The weight is described in ounces per square yard. The higher the number, the heavier weight and heavier duty the fabric is. 


We use different weight Dyneema® Composite Fabrics based on the product use.

Dyneema® Composite Fabric will develop wrinkle lines with use similar to the look of waxed canvas. This is normal. 

Some weights of the fabric may also have darker lines in the coloring. This is due to the manufacturing process and is quite normal.

Our Free Range packs are made from a waterproof fabric and are highly weatherproof. However, due to how we craft our packs, we bind the seams. Water may seep in in these locations.

We strongly recommend using a pack liner to keep the items in your pack dry! Luckily, we include an ultralight Nylofume® pack liner with every Free Range pack.
