Small vs medium
Does the finger length differ in mediums? Or is it just palm circumference? I recently purchased small, but the thumbs were a little tight, and my other finger tips didn't touch the ends. If the mediums have a larger circumference and same finger lengths, then this might be a good choice for me to size up
It is my experience that the finger length does get longer with palm circumference. I tried on a few sizes at the local cycle shop, same brand, different model, and was glad I ordered the net bigger size than I usually wear. They are just slightly tighter than my summer gloves of the same size, so i upsized. I can now ride comfortably, and may have enough room for a very thin liner, however at 34 digs riding, haven't needed one so far.
