So many compliments!

Can’t believe how light the fabric is. Have run a few times in 45-60 degree weather and the jacket has performed wonderfully. Just a light merino baselayer underneath. So happy to snag the Greek inspired design. If you’re not sure, stop thinking and just purchase this jacket. Fits perfectly and never once had to think about the jacket while I was running.
