Lululemon Long Sleeve with thumb holes and small zipper pocket

Thrifted a number of years back. Older lululemon long sleeve. Great condition. Unsure size as there is no dot, fits like a M (~size 4-6). Unsure what material it’s made of as the tag has been removed, it’s thicker. Has thumb holes on both sleeves and a small zippered pocket on the left side. Open to offers!!
