I've put in two 40ish mile bike rides with these.  As other's have stated they keep the hands from getting too cold if the temp is 45 or better. What else?  I love the screaming yellow.  For once it is also on the tops of the palm side of the first two fingers.  The bight yellow  when signaling for turns turns, allows drivers and other cyclists to see much better than dark color gloves.  YOU CAN'T BE TOO SAFE. Also they  are much thinner than my other cold weather gloves, so I can actually feel my zipper etc.  I'm 6' 6" and 180lbs.  Usually wear a XL or sometimes an L.  I tried both on in a store, and both seemed fine, but am glad I got the XL as the wrist closusre is a bit tight when slipping them on/off.  Love these!
