8 YEAR UPDATE: (February 20, 2017)  I'm downgrading my review once again from my original 5 stars.  The quality of these is just not what they were (see 5 year update below).  They are still warm and still some of the larger gloves I have found, but I bought a new pair and the velcro has already ripped off and the inner lining is completely torn with in a month an a half of normal wear.  Quality control is just not what it was when I originally started buying these.  I'm probably on my 6th or 7th pair since first discovering these, and I'm definitely looking for alternatives for next winter.  Such a shame.  These used to be the best.

ORIGINAL REVIEW:
If you are looking for a good quality fingerless mitten, this is a great pick.  Every winter I burn through two to three pair of cheaper versions of these types of gloves.  I didn't want to have to go through the same thing again this winter.  I found these on Amazon and they look they will be a winning substitute.

  As the other reviewer mentioned, this is the MENS version.  I am also not sure why either of the listings on Amazon don't mention this.  The quality of construction is very good overall.  They are also very warm.  Just tried them out in 14 degree Chicago weather and was pleased that they kept me warm even without the handwarmer.  They are also a good size.  I'm 6'7" and have a pretty long (although not particularly thick) hand and they still fit quite well.

  The only down side is that the place where the thumb folds back doesn't have any overlap and therefore can sometimes let in a little cold air.  It's not the end of the world, but I would be fine if they had left this feature off.  Also, the pouch for the hand warmer is on the inside of the fingers and is a bit bulky.  If you plan to use your fingers with the mitten portion in effect, you will find that your articulation will be on the clunky side.  Still, it's a great feature and not a deal breaker.

Overall, great gloves.  It's hard to find fingerless ones of this quality.

3 YEARS LATER:  Still my favorite!

5 YEARS LATER: (February 8, 2014) Decided to replace my old worn out mittens from a couple years ago and bought two at one go to even out the cost of shipping.  I'm sad to say that I'm really disappointed in these new pairs.  They are still nice and long and crazy warm (and it has been COLD this year...often in the single digits and as low as -15).  The lousy part though, is that the linings started ripping out within days of wearing them.  I thought it was a fluke, but within two weeks, one of the glove liners was torn at almost every seam from every day normal use.  The other liner was only slightly better.  Maybe they started using cheaper thread???  I also noticed that they changed the location of the hole for the thumb (it is almost at the base of my fingernail), and now it constantly gapes open and is a challenge to keep my thumb covered.  If it was below the last joint in my thumb, this wouldn't be an issue.  I've thought about sewing up the hole, but it's too useful to have open for use with my smart phone.

I decided to open up the second pair of gloves I bought on the chance that the first pair of gloves was just a bum pair.  This pair also started to lose its lining within days.  I am really disappointed considering how great these have been for the last 5 years.  I love them enough that I would consider still buying another pair in the future, but I'm not holding my breath.  This might be the end of my love affair with these.

Heat Factory...if you are reading this, PLEASE fix this issue.  These used to be such great gloves!
