I wear between L and XL sizes in gloves, ordered the XL and they fit "snug", not too tight, but a good snug fit like they should.  The right glove is a bit tighter, but loosened up after liberal application of saddle-soap to both gloves.  Gloves arrived in very stiff condition, but saddle-soap loosened them right up... they fit and feel great!Gauntlet slides over my jacket sleeves and makes a good seal.  I would love to see the gauntlet with a zipper to make it easier to get over my jacket, but they are what they are and do their job.Also, the description does not indicate "insulated", but they do have a fleece lining, not Thinsulate, but a generous volume of heavy fleece insulation to make them very usable down to 40 or 50-deg F.  I wore them today in 80-deg weather, and they were a bit "warm" (my hands started to sweat), but they will be perfect for cool evenings and cooler days (as Autumn approaches... which is what I really wanted them for!).UPDATE:After using these gloves for several weeks, they are not getting any better.  The leather is still too stiff, even after liberal applications of saddle-soap and Meguire's Leather Conditioner.  They hold my hands in a rigid position, and it's very easy to give too much throttle because of it.  Reaching the clutch and brake levers is an "effort" to say the least.  Furthermore, the gauntlet slides easily over my textile jacket sleeve, but is too tight for my leather jacket... I have to really work to cram the sleeve into the glove, and the feeling of tightness at my wrist is just TOO MUCH... very uncomfortable.  I feel like the Michelin Man when wearing them... unable to freely move my hands and wrists like I should be able to.  It's not a "dangerous" feeling, but it makes me uncomfortable.I've dropped to 3 stars because they are still good leather, fit my hands, and decent, mid-weight insulation... but I'll be looking for a different style/brand to wear in the cooler weather.  I'll hang on to these for my passengers to wear so their hands will be able to stay warm... won't give them much grip, but at least they'll have warmth and protection from the elements.
