+1, and not just climbing.
out here it could be really chilly in the morning and then quite sun strong in a few hours, so I wear base layers a lot. Being able to 'vent' well makes for a much more comfortable ride.
also 3/4 length zips; they seem to be 'lighter' weight, more flexible since they don't need all that finish hardware.
