Pros: very warm, easy to take off and put on, great wind blockers
Cons: liner stops at base of wrists, shell is not 100% waterproof, trigger finger kinda pointless
So big plus for warmth, I don't wear them when it is >20F, they are just too warm for me for that. Around 20F with no wind my hands start sweating in these. I have very cold hands, I've read others who say they use just the shell unless it drops to <10F. I would say that if you suffer from colder hands than the normal these would be great, but if your hands are usually not that cold in gloves or mittens (without hand warmers) of lower quality/insulation/etc these will probably be too warm for you.
If anyone skis mt. wachussett at night you'll know what I mean when I say these are great wind blockers for the minute man lift ;) I have renamed that lift the wind tunnel. I don't have to curl my fingers up or retract my index/thumb into the main section at all on that lift during very windy/gusty rides. I was pleasantly impressed with their wind block ability. Couple of times I have even held them up over my face to block the wind from my head.
Now waterproof... the liners are waterproof but the shell isn't completely. A little bit of a oversight in my opinion so watch out if you ski in wet conditions. Particularly the thumb and seams. It hasn't been a problem for me that much, but I have noticed it (only reason this rating lost 1/2 star).
They do have a separated index trigger finger, now this may just be personal preference, but I don't really see the point. I personally would rather just have all four fingers together. On extreme cold nights I have noticed my index finger a little bit colder than my other fingers, but not enough to make me want to retract that finger into the main cavity.
Now the liner does stop near the base of my wrists, not much further south than the wrist cinch in the picture. Don't expect much warmth below that.
Sizing... they do run a little big fyi.
Overall I am very happy with them and would recommend them to anyone who doesn't normally ski wet conditions (or perhaps even boarders who like to drag their hands through the snow a lot).
Look for deals, no need to pay upwards of $90 for these ;)
