I have an Olympia X-Moto (2012) and Dakar (2014), both are size Large. They fit perfectly for me. Both do come with liners (waterproof and insulated). I don't know about the Airglide. I am 6', about 190 lbs or so, wear a 43 suit and a 34 inch waist.Lots of rec's for the olympia airglide. Any input on sizing? Im 6', 200 lbs. I usually buy larges in everything, but at that size some cuts are a little tight.
