I just bought a pair of these, and have used them before. Love them. Not too warm in the moderate temps, and useful enough when it dips lower. PERFECT for when youwake up and start hiking, absolutely perfect. Blocks the wind, but not bulky.
If it gets colder, slip a pair of fingerless mittens over them. (I prefer the mittens, as my gloved fingers don't get that "bunched up" feeling inside while wearing the Delta SV's). Looking to possibly get the OR Mutant Mitts, as they have the thumb AND index finger seperate from the rest of the enclosed mitten.
