I purchased these gloves for my cold-weather, daily motorcycle commute (about 30 min each way).
I use these for temps below 50 deg F,  IMO and personal thresholds, these are effective down to mid 20s (again, within the context of 30 min commutes).

I've used these gloves since late Nov (about 3 months now) and, because they've held up and performed beyond my expectations, I felt obligated to write a review to let the manufacturer and others know.  Some other points;

1)  Not waterproof, but fairly water resistant
2)  Excellent grip on the controls (brake/clutch lever)
3)  Excellent dexterity (e.g. unzip jacket, grab small items, etc), especially after break-in
4)  After 3 months of constant use, no sign of cracks or wear other than usual crease marks

Best cold-weather commuting gloves I've purchased so far!
