Versatile, with lots of features.
I have worn this on a few spring Mountain bike rides in Northern Utah. It would easily be good on its own into the 80s, and paired with a vest and arm warmers would be comfortable down into the mid 40s. The funnel-shaped collar zips up nice and high. The zippered pocket has internal wire routing for an ipod or headlamp battery, and there is an integrated glasses cleaner inside the hem. This is going to be my go-to jersey for the dirt this year.
