Runs a little small for a change? Sometimes these Winterized/Repel long-sleeve running tops run a size too big, like they’re weren’t sure if they intended them to be worn as a first or second layer. I’m between Men’s S/M. Small in the DFADV Stride tops because they’re huge. This one fits like a first layer, but has juuuuuust enough space if you wanted to wear a single layer under it. Only gripe is that the collar sits a little wonky, unless you have it zipped all the way up.
