Purchased a neoprene Engine jammer and how good was this kept up with the top bunch 3rd overall in the 350m Bermagui Ocean swim and 9th Overall in the 1.2km on the same day. This neo jammer is a fantastic product for open water its a good as a full wetsuit great 😊 product sturdy well made and fashionable. Never race in anything other than Engine swimwear at 70yrs old and racing in this gear for over 14years I still love and believe it’s the best on the market. Steve de Lorenzo
