Rachel G.wrote a review of Smartwool Merino 250 1/4-Zip Top - Women's on March 7, 2019
Familiarity: I've used it several times
Fit: True to size
This piece looks great from the neck down. It's super soft and I don't find it itchy at all. Also I got the blush color and it's muted and very pretty. I wasn't sure about running in wool, but I have really enjoyed running in this and not having to wash it every time.
The only downside is the neck. The zipper is very stiff so even when unzipped it stays erect and rubs against my neck in a slightly uncomfortable way. Not a dealbreaker for me, but it's definitely not ideal, and if you are bothered by something rubbing on your neck you're probably not going to like it.
