About MadPax LLC Born from pure imagination, MadPax LLC strengthens their ideas and lines by continually challenging each design to bring out the most unique results possible.

The conclusion is their innovative product line of backpacks. MadPax LLC is a company you can count on to provide premium customer service and the most ground breaking designs. Bring one home today!
