From the Seller: Recently lost 80 pounds and went from an XL to an M, so clearing out my entire closet. This piece was only worn 3-4 times (in rotation with a navy version). It is from this past spring 2023 season (purchased in April). Super comfortable for working out, jogging, or running to get a bagel. Has a nice knit finish and a barely noticeable (but not distracting) vertical weave to it. I hop that make sense. It's not a vertical stripe or ribbing. It's very subtle, but speaks to quality. I will be replacing these in my new size. From the Manufacturer: This ultra-soft 1/4 zip is a versatile layering piece that provides all day comfort, stretch, and warmth. Designed as the perfect midlayer for the office or date night, the Commuter 1/4 Zip boasts a comfortable sweater knit material with a tailored fit.
