Just a few days ago, I ordered a Fourth Element Argonaut drysuit. I was Biomapped at DEMA last Nov. Hoping that I can get a decent fitting suit with little drag, but durability. Unfortunately, my 2 TLS 350's just have not held up the way I would have hoped. I am constantly fixing leaks. I opted for the full Flex- style material. My other choice was the Hybrid (Kevlar upper & Flex lower parts). The Kevlar just looked rather clunky, bulky & heavy to me. I could be totally wrong. I am looking for a suit that is more streamlined, without sacrificing mobility & DRY (big one). Now the hard part,.... the wait... Will be about 10 weeks lead time..... Tick, tock..... Tick, tock....
