Great Fit, Great Feel — A New Go-To for Workouts
Special Size: with Contrast Trim, Size: Medium, Color: Navy/White
Really impressed with this workout tank! The fit was spot-on — snug enough to stay in place during movement but not too tight. It didn’t ride up during my workout, which is always a win.
The material is soft, breathable, and wicked away sweat really well during both strength training and cardio. It honestly reminds me of the higher-end athletic tanks I’ve tried — same feel, but at a much better price point.
Definitely one of those pieces you’ll want in multiple colors!
Pros:
✔️ Comfortable, moisture-wicking fabric
✔️ Stays put during workouts
✔️ Flattering and functional
✔️ Great quality for the price

Loose under arms, flattens you out
Special Size: with Contrast Trim, Size: Medium, Color: Black/White
I saw an influencer recommend this workout top, but was disappointed in the look and fit. It was saggy under the arms and flattened by bust in an unflattering way. This was returned.

Excellent quality ~ Great price
Special Size Type: Quarter Zip, Size: Large, Color: Flamingo Pink
Excellent quality, bright pink a beautiful cheerful color, washes well. Fits perfectly, ordered a large from fitting nice long sleeves. Fabric is soft and not too thin or thick. Great price, wish it came in more colors I’d buy a few more.

Definitely an essential jacket for athletic-wear & flattering
Special Size Type: Full Zip, Size: XX-Large, Color: Black
Great quality for a great price!
I was looking for a versatile athletic jacket to run in that fits over light tops & found this on Amazon. There were only a few left so I grabbed it right away, so glad I did! It's warm enough for early fall, I live in NC so I will probably use it throughout the winter too bc it's warm here. I feel like the arm length is a bit long & the sleeves a little bit tight under LS Tops but are meant to be. This is a form-fitting jacket, it does run small. I usually have to size down from an XXL to an XL in Amazon Essentials clothing bc they run big but this jacket fits me in my regular size XXL. I tried to find this type of jacket at a few different places & already out of stock in October! If it's available, buy it! You'll love it! I hope more colors are available in the future!
