Folks, hope someone can answer a query for me. I have a Whites Fusion Bullet drysuit, purchased shortly before they became Aqualung branded. It is the newer version with the SLT technology. My question is, and I can't seem to find an answer, would a replacement outer purchased from Aqualung fit the Whites inner? They look to all intents and purposes to be the same but is similarity only so at a cursory glance?
