What's the deal with Dyneema Composite Fabric (DCF)?


Here at Superior Wilderness Designs we use two main types of fabrics for the body of our packs: X-Pac and Dyneema Composite Fabric (DCF). Both are great options for making ultralight backpacks, and in this FAQ , we’ll be going over DCF and the properties that make it unique.


DCF (formerly known as Cuben Fiber) “is a patented, high-end laminate fabric constructed from non-woven composites utilizing space-age DSM Dyneema fibers.” In laymen’s terms, it's a super waterproof, incredibly strong (boasted as being 15 times stronger than steel), non stretchy, and ultralight fabric. Originally created for sailboat sails, DCF has become the premium fabric for those looking for the most ultralight products on the market.


While DCF comes in a variety of different weights, we use 2.9oz 50D DCF for the main body of our packs and 5oz 150D DCF for the bottom. The 2.9oz DCF is the lightest pack material we offer, and the 5oz DCF is a slightly thicker accompanying material that is typically used in places where more abrasion occurs (hence the bottom of our packs). While lighter versions of DCF do exist (.51oz, .67oz, .74oz, 1.0oz, 1.43oz…), these fabrics are used primarily in stuff sacks, tarps, tents and bear bags. DCF has a unique and unmistakable feel, and this texture is sometimes referred to as “crinkly.” While not particularly noticeable, it is a noisier fabric than other alternatives on the market.


While DCF is an incredibly waterproof fabric, sewing naturally creates small holes in any material. However, all of our DCF packs come fully seam taped for maximum water resistance, and seam strength. While the packs aren’t waterproof, they are about as close as it gets.

How does DCF compare to our standard X-Pac material? Simply put, DCF packs are slightly lighter and more water resistant. Durability wise, the DCF packs have about the same durability as our VX07 packs.
