Planning to get a set of the Xerotherm Arctic to go under my Protec as a step down from the 200g undersuit I have now for when things are a little warmer.
Should I be aiming for a 'snug' fitting but obviously still maintaining mobility or do they work better with a loose fit?
Only reason I ask is that by the sizing chart I'm in the middle of the 'large' range but one store I've spoken to insists that I will need to go up a size or they will be too tight.
My own personal view is that they they should be snug but allow for a layer or two of thermals underneath - while still allowing full range of movements.. As for fitting - go try one on! Take a couple of Tshirts to put on over each other - or the thermals that you would wear when its colder and try it on.. get a mate to come along and observe your reach in both just the artic and with both layers on..
