Interesting that the pocketless still cost you 2 sec/100yds. I wonder how much it would have been with pockets.
Keep in mind that I’m a pretty slow swimmer so we’re talking maybe 2%. Might be less in open water. The top feels pretty snug but I can feel it sort of puff out when I push off on turns. I was most surprised that the old trick of un-zipping the top and stuffing it under my swim suit really wasn’t much faster. Kind of like wearing an extra suit for more drag in training.
