........Apparently you already bought your suit but for future references, JMJ and New Horizon have the Tplush material which has some sort of fuzzy liner that also help with getting in and out plus keeping you a bit warmer than a typical 7mm suit.
Actually, the merino wool lining doesn't need a rashguard. It is a plush type lining that is actually quite easy to get into when wet, if it's the right size. I am convinced his suit is just too small. They also will dry overnight in most conditions (turned inside out), so on multiday dives you don't get quite the 1st dive in the morning shock of other suits. You can even run it under the shower (if the boat has one) and warm it up a bit.
