The LS would also be my PJ top.
It is a bit tough to predict what weather I will run into in terms of temperatures. I will likely hit Colorado sometime in mid June and of course will be at higher elevations for much of the rest of the ride to Oregon. Even thought about packing a down vest and wool beanie to use once off the bike later in the day and into the evening.
