I have shortsleeve and longsleeve Smartwool jerseys, one of each. Both have back pockets; the longsleeve one has a full zipper and is a heavier fabric. I also have some of their microweight t-shirts and lots of their merino socks. I'm a fan; their process (others have similar) makes the wool machine washable with little if any pilling, and (to me) not scratchy at all. I got the cycling jerseys on sale, maybe through Sierra Trading Post, but you have to watch there like a hawk for deals. I'm not even sure Smartwool is making cycling jerseys anymore. Another advantage: their only logo is a very small same-color figure of some kind, practically invisible.

Only problem with all wool is that indeed moths are fans, too.
