The draw: Swimrun specificity
The first thing you’ll notice when you race a swimrun: You’ll want to cool off during the run without taking off your suit, so Zone3 used a front zipper. The second: Legs chafe, so Zone3 made the legs a thin 2mm to add some extra buoyancy without feeling restrictive on the run. The arms are an extremely flexible 1.5mm neoprene and zipped up, the top will keep your core toasty. It also features an enormous back pocket for fuel and whatever else you want to stuff in there. But we found this unisex suit a bit restrictive across the chest for the ladies and tough to take entirely off over the shoulders without help. Good thing swimrun uses the buddy system.
