Other reviewers are right that these run small--Castelli says I'm on the lower end of their range for medium and they fit me well. But, if you're somewhere in the middle or upper end of any given range, you may want to go up a size at least.
They're snug, but comfy--love the finger tag to help with taking them off. Without those, it would be a chore to take them off at the end of a ride. Padding appears good for what they are--simple (i.e., not gel equipped) gloves. Price was very reasonable. They look well-constructed, but can't yet tell about durability.
Easily could be a ski glove as well as a cycling glove. I have found it to be quite comfortable and warm in temperatures in the 20's - I haven't been out in the teens yet. Putting the pinky within the same sleeve as the ring finger does not hamper shifting or any other function of cycling, but certainly helps with warmth.
After my maiden ride with these gloves I questioned if they were any better than gloves I owned, but with each subsequent ride I felt I made the right move.
Let's start with the one issue I see in this piece. The zipper is dead center and hits you right in the adams apple. It should be offset. With that in mind, if you are between sizes you need to go with the larger one, otherwise the pressure on the neck will be more noticeable. How do I know that. I first bought the L and then got the XL. The L fits well, but I feel pressure in the neck. The XL is looser of a fit. I would prefer the large with a redesign on the neck area.
The unfinished sleeves are awesome - providing no bulk when layering. Everything is like a warm hug with this piece. I feel it should fit fairly snug so that you can layer - putting this mid-layer over a skin layer and under a jacket - to add extra warmth. The current Assos jackets are meant more for high intensity efforts where you are cranking out heat. If you are not putting out a lot of effort you need something like the GT mid layer. This philosophy is an exconmical one since you do not need a bunch of different jackets for varying conditions, you just layer in what you need by combining fewer layers to achieve the jacket of the day.
I prefer this over the older style of dedicated jackets. The GT mid layer can be used for other activities than cycling. I use it as a warm compression layer for golfing in colder weather,
For pretty much everything else I wear Castelli L(arge) size (bibs, jersey, jackets, etc) so I thought I should get an L for the arm warmers too (it doesn't help that Castelli does not publish a sizing guide that considers hand length/circumference). Well, that was wrong, the L warmer barely sits on my hand, it's probably not going to slip on its own but it doesn't feel like it sits firmly on the hand either. Next time I'll get an M...
The other problem is that some of the stitching has already started to come off after 3 wash cycles (I use the lightest setting on the washing machine for bike clothing). I think my cheaper Pearl Izumi warmers held longer.
