INDUSTRY'S BEST FABRIC

All Rockgeist gear is constructed with premium Dyneema®, X-Pac™, or Cordura® fabric. These fabrics give unrivaled durability and performance for their weight. Combined with meticulous design and exceptional workmanship, these materials are an essential element in delivering best-in-class gear.

X-PAC™ FABRIC

X-Pac™ VX21 is the workhorse fabric for bikepacking gear and is constructed of three layers; a 210 denier nylon face (hence the 21 in VX21), a black polyester X-Ply™ grid on a PET film, and a 50 denier taffeta backing. The outer 210 denier face is then treated with a durable water repellant finish. Collectively these layers create a very technical fabric with exceptional abrasion resistance, low stretch, and durable waterproofness. VX07, X33, VX42 and X50 are similarly constructed with their respective denier face (70, 330, 420, 500).  However, X33 and X50 have a shiny backing rather then the matte taffeta.

CORDURA® FABRIC

Cordura® fabric is constructed of a specialty nylon weave with a waterproof coating and has exceptional resistance to abrasion and punctures. 500 denier Cordura® is typically used for the face of gear, while 1000 denier and ballistic 1050 denier is used for abrasion prone areas (e.g., the spine of bags). Ballistic 1050d is standard on the spine of all Rockgeist framebags, however, 1000d Cordura® is more then sufficient to take the abuse at a little less weight. Please see the weight graph below for comparison between all Rockgeist fabrics.

WHICH FABRIC IS RIGHT FOR ME? X-PAC vs. CORDURA

VX21 and 500d Cordura are often viewed as “equal” when it comes to function but there are a few small differences:

  • VX21 has a slightly lighter base weight. See the weight graphic below for comparison between X-Pac and Cordura.
  • When out in the wild, X-Pac will also absorb less water then the 500d Cordura. This makes VX21 an ideal choice for riders who make lightweight travel a priority.
  • X-Pac waterproofing is slightly more durable since X-Pac has a dedicated waterproof layer versus the waterproof coating of Cordura.
  • 500d Cordura has slightly better abrasion resistance then VX21 and is great for gear that might see a lot of rubbing.
  • Aesthetics: X-Pac has a more technical/performance look while Cordura has a classic “feng shui” that may align well with you and your bike.

COLOR CHANGE FROM SUN EXPOSURE

How will your fabric colors fade over time? To help answer that question a few of the more popular fabric colors were rounded up and exposed to the Sun’s UV energy for 2 summer months. The intent was to rank the fabric colors by how much they fade, not necessarily to show what your fabric will look like after a few seasons. Keep in mind if you ride at high elevation in Colorado your colors will fade much faster then if you ride in the dense rainforest in Pisgah, NC.

METHODS

A fabric swatch of each color was sewn together and placed on the workshop roof. Sun exposure lasted from noon to about 7 pm for 2 summer months. After the UV challenge, before and after photos were compared by taking the average RBG values of each swatch to obtain a single RBG color. The luminosity of this single RGB color was then used to calculate a percent fade.

CAMO FABRICS

Due to the variable multi-color camo patterns an average RGB color was not calculated. For these patterns, images of before and after the UV challenge are provided to give a qualitative comparison.
