Garments with an Adjustable Hood feature draw cords with toggles or other adjustment mechanisms, to change the size and shape of the hood to better fit the head of the wearer. Such hoods usually adjust independently around the head, and around the face, for a snug fit and optimum weather protection.
Rip Stop is a lightweight nylon fabric with interwoven rip-stop reinforcement threads in a cross hatch pattern. It's woven with a coarse, strong warp and filling yarns at intervals so that tears will not spread. Rip-stop is used in construction of hot air balloons and yacht sails but in this case very effectively on outdoor clothing.
