I was at a local thrift shop today, when I noticed they had some Goodnites in stock. After putting the three loose pairs into the plastic I bought them.
But why would I buy them? I thought they were L/XL, I was wrong. The impression of L/XL came from the Skate design on the first one I saw, and I didn't even bother to test if it was actually that size.
But, the interesting thing I find with S/M is that, they fit... sort of, but are about an inch or two smaller in rise than the L/XL despite being made for kids less than half the size of the official upper range of Goodnites products.
