Product Description
Made of Evazote® foam, these pads are made with a unique high pressure nitrogen gas solution process. High quality extrusions and cross-linking of solid polymeric sheets are impregnated with pure nitrogen gas at elevated temperature and extremely high pressure. Then the impregnated solid sheets are expanded in a huge low pressure autoclave. This process results in an extremely regular and uniform cell structure in the foam.
What this means to you is the foam is amazingly light and strong for its density. The pads are tough, flexible and resilient, and exhibit good UV stability. As a closed-cell foam, they will not absorb water.
The foam is cut into an "egg crate" pattern for comfort. The base is 1/4", and the convoluted portion rises a maximum of an additional 1/2" above the base, for a total pad thickness of 3/4" maximum. Since the foam protrusions are solid foam instead of formed, they do not compress over time in the same way the Z-Lite™ pads will.
The 3/4 length pad is too bulky to fold, and has to be rolled, either inside the pack (if it is large enough like a G4 or Mariposa), or on top (where it can be held in place by the Mariposa "Y" strap, for instance).
