Claim:
A water migration resistant device attachable to a fabric and releasably engagable with a mating snap fastener member, the water migration resistant device comprising: a first member having an engagement portion on a first side and being releasably engagable with the mating snap fastener member, the first member having a fabric contact side opposite the first side; a plurality of first fabric gripping protrusions on the fabric contact side of the first member, the first fabric gripping protrusions being non-fabric-penetrating protrusions; a second member lockingly engagable to the first member and having a fabric contact side; and a plurality of second fabric gripping protrusions on the fabric contact side of the second member, the second fabric gripping protrusions being non-fabric-penetrating protrusions; wherein: the plurality of first and second fabric gripping protrusions are offset from each other such that during use of the water migration resistant device, the first and second members are lockingly engaged with each other with the fabric captured between the first and second members without the first and second fabric gripping protrusions penetrating the fabric, the plurality of first fabric gripping protrusions are arranged in a first circular pattern about a center of the water migration resistant device, the plurality of second fabric gripping protrusions are arranged in a second circular pattern about the center of the water migration resistant device and are radially offset from the plurality of first fabric gripping protrusions, first portions of the fabric captured between the first and second members are squeezed by the gripping protrusions and are compressed relative to second portions of the fabric that are not squeezed by the gripping protrusions, and the first portions and the second portions of fabric are alternately spaced in a radial pattern and an axial pattern between the first member and the second member.
