For 2011, we made the 40B out of Woven/NonWoven Dyneemaź, making out of the best material we could create. This is the pack of choice for folks with shorter torsos for cragging and big weekends close to home.
The 40B responded to the desire of folks like Kelly Cordes and Max Turgeon for a pack that would work for Alpine Cragging or serious routes in more civilized areas. The 40B Dyneema is the same pack, just lighter and more durable.
With our X-Pack Dyneemaź material on the front panel we deliver the same incredibly load transfer our traditional WorkSacks. It is a robust and durable pack that is less than two pounds for use as a light hiking bag today and in the years to come.
