I'm resurrecting this thread.
I just purchased 3mm and 5mm Elastiprene Merino Pinnacle wetsuits as well as a 3mm Bare Velocity. The Bare fits PERFECTLY on me, but the Pinnacles are a bit hard to get into. They FIT... but they are not as comfortable a fit as is the Bare.
My question is -- do the Pinnacles stretch at all over time? It is so close to a good fit. Just a tiny bit too snug. I don't think I can go a size up -- it is close.
I'm thinking of keeping all three, though. The Bare doesn't look like it will be as warm as the Pinnacle is sure to be; I can use it on surface snorkeling trips in warm water.
