well, i was plenty comfy in my 3/2 w/ 3mil boots & 1.5mil gloves for about 2 hours. took a couple sets on the head & wished i had a squid lid, but that was the only time. after 2 hours, i ran out of warmth & fun, pretty much simultaneously.
i'll keep the 4/3 out for those cooler days, but if the water gets much warmer, deff. won't need it. there were guys out w/out gloves today.
