Rugged merino wool birdseye half-zip sweater

I like this sweater but it started pilling after wearing it one time

Bought this sweater in medium. I'm 5.8 and average build. My 5.2 wife now wears it. I think that sums up the size issues. Its almost as if it was mislabeled

I'm a fan of this sweater. Beautiful pattern and excellent when layering over a shirt and under a jacket or coat. That said, there's nothing rugged about this. It's quite thin and stretchy. If in between sizes, I would recommend the smaller size.
