Size Up Black Y Back Tank

Finally, a men’s tank top that is both comfortable and extremely flattering.  The Size Up Black Y Back Tank features a slimmer fit chest that relaxes slightly near the bottom.  It offers a Y shape back that accentuates those back muscles you fight so hard in the gym for. The chest is cut to perfectly reveal your pecks and upper arms.  

Size Up has thoughtfully added a coop bottom that helps make this tank more tailored and modern. The front is adorned with the tasteful wing Size Up logo.  It also has a smaller logo on the bottom right side. This is definitely a tank even your most hardcore gym buddies will ask about.

The Size Up Black Y Back can easily be paired with your favorite gym short or jogger.  Wear it out and about running errands. Wear it with your swimsuit at the beach. The opportunities are endless.  

The Size Up Black Y Back tank is made with polyester.  This allows the tank to retain its shape while offering maximum comfort and breathability.  The Black Y Back tank fits true to size. This tank comes in many different colors. Buy one for each gym day!

Every one

Every tank I got from Sizeup is fantastic. I see them around but I’m surprised they aren’t the most popular tank in the country yet. They’ve been great for years. This one isn’t even my favorite, but it’s a great black tank if that’s what you’re looking for.
