Adding this option to your order means that we will double layer the bottom fabric on whichever pack that you order. This effectively doubles the life and abrasion resistance of the bottom of the backpack which is one of the spots on the pack that can wear out most easily.


VX42 adds about 1oz, and VX21 adds about .7oz to overall pack weight. 150D DCF adds about .7oz.
