I never heard of "tunneling" and I'm from the same time period college late 80's early 90's. I'm sure we had a similar term but can't recall at this moment. I like the jammer not for swimming but for running or hiking I like how the jammer keeps the muscles from tiring as quick. I feel the difference when I wear the regular running shorts.
