It looks like H6O or H6C. The whole creed is very worn and it is still really wet (just took it out of dunk at 11).
The zipper fabric is red and what edging there is (and it doesn’t exactly look original) both are red, but the bag bled berry and fuchsia on the towel and is currently a gorgeous shade of what the Brits call conker.
H6 would have been Fall 1996, Currant hadn't been introduced yet. Let me see if I can find anything in the catalogs from around that time.
