US Patent 7617575 Water migration resistant snap fasteners

Snap fasteners are attached to a fabric or substrate and resist water migration from one side of the fabric or substrate to an opposite side of the fabric or substrate. The water migration resistant snap fasteners resist water migration through the fabric to which the snap fastener is attached while maintaining secure attachment to the fabric. The water migration resistant snap fasteners have radially offset patterned circles of gripping protrusions which do not penetrate through the fabric. Also, the radial patterned circles of gripping protrusions securely grip the fabric and maintain the snap fasteners in the proper location on the fabric.
