SummersHi @Summers ! WoolPRO will have a more contoured fit than some of the other brands, like IceBreaker. It's more of a European fit. @AlliMarrier had attached the size chart in an above comment, but it's a little hard to find so I'll place it here:
Summers@Summers , both shirts will have a drop tail. This longer back length stays tucked in better when being used for layering, and provides more coverage in a variety of activities. If you need an exact length for one, let me know which size and whether it's for the Agena or the Scout, and I can give you the measurement :)
