Lululemon Swiftly Tech Long Sleeve 2.0。I purchased this from a local boutique and it’s a little too big. I missed the 14 day return sadly and they don’t have my correct size. I love lack of color hats for both the quality and style. Description below: Our best selling Val Diamond silhouette, now in a beautiful neutral light brown hue. A vintage inspired men’s silhouette featuring diamond crown with flicked edge.
