Looking to go lite and possibly "up" after a recent tough 9 miles on three rocky peaks that highlighted my endurance limits to carry. Found this site after a link from black cat tarp project instructions. Dusted off the sewing machine and practiced flat felled seams In scrap nylon to begin this new adventure in making my own gear. I'm a chemist in a company that makes silicones and other textile treatments/chemicals so I appreciate the requirements of advanced materials for this area and have access to some cool goodies. Hopefully some customers work with ultralite fabrics and i can access them.
