These Klim gloves fit more like American branded gloves than European branded gloves (which run a bit smaller). If you have experience with brands like FirstGear, Tour Master, Joe Rocket etc, I think you’ll find the fit comparable. If you have no previous experience with glove sizing, go here for help.
This particular style is a little more snug going on but is normally sized once you are past the cuff. The goat leather should stretch just a bit over time so snug is ideal for a new pair.
