Webbing

NYLON WEBBING
      The most commonly used webbing for outdoor gear.  A nice flat  weave allows it to work well with almost all buckles.
     
POLYPROPYLENE WEBBING
       Good webbing for long time sun exposure and marine use.    Has a coarser, “loopier” weave than the nylon webbing.

GROSGRAIN
      A very lightweight nylon webbing.  It's especially good for binding off fabric edges.
