I have had a pair of these for nearly 2 years now.

They are starting to wear thin at the seams (no loose stitching or holes but the material is wearing out) and the light padding in the palm is getting a little beat but I still love them.
They are windproof and water resistant and offer some very light insulation.
I have worn them on my motorcycle and on my bicycle in temps as low as 25 or 30 and they work pretty good for short distances.
30 to 35 and they are good for an hour or so outside.
Beyond 35 and they are good indefinitely.
They will surprise you for as thin as they are.
Since they are so thin the dexterity does not suffer too much
I was totally bummed recently when I thought I had lost them.
I was also totally going to buy another identical pair but luckily the old ones popped up so I am going to wear'em 'til the wheels come off.
I also have a pair of the Duluth Gauntlet work gloves and they are just not very flexible and it does seem the fingers are needlessly long.
I thought they might flex more after they broke in but I have used them pretty hard for about 3 months now and they don't seem to be loosening up any.
However they are pretty warm and good for just wearing and walking.
