Lululemon Shirt

well I feel that this is a rare Lululemon shirt it's definitely unique from all the Lululemon I've ever seen Maybe that's why I can't seem to find it on Lulu Fanatics unless I know the name of the shirt it won't bring it up. Lululemon has had hundreds or thousands of shirts come out in the last 20 years. I don't even know how old it is but it looks new. So I can't seem to find the name or picture of the shirt as well as the size anywhere lol. One thing I can tell you is that it is 15.5" in across the chest when laid flat as well as 12.5" across the waist when laid flat.It looks to me,like it's a running shirt. It has a lot of characteristics of the other Lululemon track shirts.Its thin ,lightweight, soft, has a cool hole in the hood for your ponytail .Its in very good condition. It isn't pilling , stained, ripped or anything. 10 outta 10 forsure.It may look just white but it's not. It has little gray dots everywhere. It has a little secret pocket on the left hand hip.Also has triangle thumb holes on the the wrists instead of the slits which is a nice change.
