Tight fit, may affect how well it works for cold weather
I usually wear a large and that's what I ordered. They were tight the first time I tried them on but thought they'd stretch (they do have a neoprene like material). They never did. One thing about tight gloves, they limit circulation and movement. Both are bad for cold weather. Otherwise they are well made, good materials and workmanship. My only recommendation, is order one size larger.
