Composition - 100d or 210d Robic Nylon Ripstop with a PU Coated Interior.
This fabric is very strong and durable for the weight, and is the most affordable body fabric we use. The PU coated interior makes the fabric waterproof, but the nylon fibers may absorb moisture over time. Wet conditions can add weight to the bag and the material may sag.
Composition - 70d Nylon Ripstop, Non-woven Polyester Face
When considering price, weight, strength, and performance, LS07 is a great goldilocks fabric. While not the strongest or the lightest on this list, it does blend the strength of nylon with the water-repelling properties of polyester at a relatively low cost. Great for humid and wet environments.
Composition - 70d Nylon Face, Poly X-Ply, 0.25 mil PET film, 50d Poly Taffeta
VX07 is a rugged composite, blending the durability of a nylon face with the waterproofness of a film backing and the strength and stability of a poly X-Ply. This fabric does not experience sag and is a great do-it-all option.
210d HDPE Gridstop
Composition - 210d nylon ripstop with an HDPE grid, PU coated interior.
If durability is your main concern, go with 210d HDPE Gridstop. A classic fabric in the ultralight community, 210d HDPE Gridstop has stood the test of time and has the potential to last many thousands of trail miles. The nylon fibers can absorb moisture, but the PU coating on the interior will prevent water migration through the fabric in stormy conditions.
2.92 oz DCF Hybrid
Composition - 1.43 oz/sy Non-Woven Dyneema Laminate, 50d Polyester Face Fabric
For many, the price tag of 2.92 oz DCF Hybrid is worth it. It is the lightest pack fabric we use, and is incredibly strong. The fabric absorbs no water, and is great for wet conditions. Repairs using DCF tape are easy. We seam tape all of our DCF packs for seam strength, but still recommend a liner to ensure contents remain dry.
