I purchased one of the MathCat Workout Tank Tops with a built-in bra and loved it so much that I immediately bought another — and I’ll probably buy more! They’re super flattering, fit perfectly, and hold up great after washing. Comfortable, stylish, and perfect for the gym or everyday wear. They run true to size.
Diana –
I live in these. Bought two colors! so comfy and they wash and dry easily. Kept it’s quality over many washes. Literally wear this every week to work out or when I don’t want to wear a bra!
Kimberly Kelly –
Fits great! I even left the cups in – they did well holding their shape after washing. The fabric is soft. I cannot wait to wear it to the gym. I would have normally have purchased a medium but the reviews suggested sizing down…I AGREE! Ordered a small and it fit like a glove.
Kimberly Kelly –
I bought one of these tops for a trial run. I want to love tops with built in bras but not a single one worked out for me before this one. I went back and bought several more in different colors.
Utility: The top can go from the gym to a BBQ to a layering piece under a blouse to be worn to the office. The weight is light but supportive in a non- binding way.
Fit: The only thing I would caution is that there might be vanity sizing as I ordered a small but it fits a little bigger than expected. This is the ONLY reason I didn’t give that 5th star.
All-in-all a strong “recommend” and have worn it nonstop since I purchased. The photos I’m including intended to show that while lightweight, it is not see through. Color choices are excellent and quality is good – washes easily and I put everything in the dryer!
MJL –
Great top for working out! Keeps me tucked in tight and gives the girls a massive boost up
BLu –
Love this top. The fabric is thick and soft. The built in bra provides good support (even for 30DD) and it washes well, no fading/pilling. It’s also really cute, I bought more in other colors and love them all (except the off white one I tried that was too sheer, so you could see the line of the built-in bra, which I didn’t like)
Lauren Tiemeyer –
Great, flattering top.
Really pleased with how good this top looks. There is a build in bra with removable pads. The band size is probably a tiny bit on the large size – I would prefer it smaller, but the body of the top is not too tight so I would recommend ordering your usual size. The cup size is generous.

135lbs, 34D and have a relatively short torso, ordered small: Fits well across the chest, straps not adjustable but surprisingly at an adequate length and comfortable, but sadly I find the overall length too short (mostly because it keeps riding up and I like camis tucked inside my pants). Photos shows were the shirt keeps ending up after minimal movement. Otherwise great quality and fit.
Lauren Tiemeyer –
This fabric and fit is amazing! Total dupe for Express bra camis. Note that is just Medium support so maybe not ideal for larger chest and jogging but perfect for athliesure wear and super cute with jean shorts or skirts! Could be perfect for layering as well.
Alanna Klassen –
Nice workout top! Usually a size M and I purchased that first and it was a little loose and minimal support for the girls. I ordered a S and I feel much more support and still fits great!

Sav Smith –
This is perfect! Such good quality and fit. I was worried the bra wouldn’t fit my chest because I’m a nursing momma but it fits perfectly and even allows me to easily nurse! The color is also exactly as shown! I will be ordering more colors!
Tara –
I was so disappointed when I could no longer get a racer back cami from Amazon (Hanes). They haven’t carried the one I love for months. I decided to give this one a go even though I am not a fan of a built-in bra. Well, I LOVE this one. I have ordered 3 white and 3 black. I wear camisoles under all my shirts. I have now worn this one the last few days without a bra. It is great. I don’t know that if you are a more endowed person, it would work for you. I am pretty small and ordered mediums. They are great!!
Sharon Griffith –
The fit is great. The built in bra isn’t supportive but it’s great to cover what it needs to. However, this is more for an aesthetic or just hanging out. Wore it to the gym by itself (could be my fault for not wearing a sports bra) and couldn’t even workout cause I felt like I was going to spill out of it.
Ebays –
LOVE these tops. They remind me in texture of Lululemon’s Swiftly tank, but with a ton of stretch. These tops are so incredibly comfortable. They’re supportive without being restrictive. They are high-quality and hold up to repeated washing with no shrinkage. I now have them in almost every color they make. The material is thicker and flattering, but not hot. I normally wear a size 6 in Lululemon and wear a size small in these tops. A nice shorter length without any exposure of your belly button.
Shayli Burgi –
I’m a mom of 4 with a constantly changing body and I’m also group fitness instructor for a HIIT class. LOVE this top! Definitely listen to the reviews and size down. I have a lot of extra and sagging skin in the tummy area, so every time I size down, it looks super unflattering or sucks in my middle way too tight. But the shape of this is perfect, secure up top but flaring out slightly and stops right under my belly button so I don’t feel too exposed! Soft and stretchy too. I’m 135 and 34B, usually buy everything medium (and bought one just in case- it was a little too big/too much fabric) but small is great. I’m definitely getting in more colors!!

These are real quality tops. I bought black in medium and white in large. Had to return the large as it was two big but ordered another white & black and also a red in medium.
The fit (medium) is perfect for me. 5’5” 150lbs 36DD. The bra top fits so smooth and is uplifting. These are the best fitting/looking tanks tops I have bought, including the expensive shapewear ones.
Great layering pieces for summer and winter travels. Quality material. I am very happy with this purchase!
Nao77 –
Looks so good, I ordered my true size L ( 5’9, 190lbs) and it fits perfectly. The bra is supportive enough to strength train in it or walk/stairmaster but if you have a bigger chest it’s not running friendly. But amazing top I highly recommend!!

Marcela –
Great quality, super comfortable material. I feel like it runs a little big, for reference I’m 5.6, 130# and the small was too loose on me, if they have XS I will exchange it.

I like it! 36B

Love this tank! It’s super comfortable, supportive, and flattering. The built-in bra is a big plus, and the fabric is soft, breathable, and moves easily during workouts. Fits true to size and works great for the gym or yoga. Definitely recommend!

Sharon Griffith –
This workout top is a great find! It fits well, looks super flattering, and gives off definite Lululemon vibes at a much better price. It washes well and feels great during workouts. My only wish is for a bit more bust support, and I’m not totally sure how long it’ll last but for the price, I’m impressed. Still a regular in my rotation!

Lis Viilu –
Absolutely love this tank top! The material is buttery soft but still super supportive, and the built-in bra gives just the right amount of hold. It’s breathable and stretchy — perfect for everything from yoga to HIIT workouts.
The fit is incredibly flattering, especially the way it hugs the waist without feeling tight. And the color? Even more vibrant in person! I’ve already ordered a second one in a different shade. If you’re looking for a cute, functional activewear top, this one’s a winner!
Kevin Driscoll –
The black one is very good and the sizing is great. I got an extra small., I am 5’1” and I weigh 130 pounds and I believe I am a B/C cup 34. The length is perfect and overall, it was perfect except I had to exchange it for a new one because I was sent a used one covered in deodorant and smelled like perfume. Keep in mind the other colors you may order off in sizing as I ordered the green one because the color was so beautiful, especially if you have a tan and short shirt that squeezes the top chest part on the sides From the band of the bra. I might go ahead and order the green one again in a small instead of the extra small and see if that helps at all. But overall, it’s a great shirt. I wear it to the beach for swimming as dry super quick or every day for errands ,really nice shirt.

I wear this top every week for my workouts. I love the color and fit. It fits true to size. So I’d suggest sizing down for a really tight fit. I can tell the material doesn’t feel cheap either. Most importantly, I like the built in padding.

Love! Will size down as it’s baggy around the stomach. Mixed reviews made me order up. I got white & it’s not see through what so ever, flattering, light 10/10

This is surprisingly great quality! The color looks exactly as described and the cut/shape is very flattering. The material is form fitting, but still stretchy and buttery soft. I’m a C cup and it holds everything in well. We’ll see how it holds up through workouts and washes, but overall, I’m impressed!

Shayli Burgi –
Obsessed with these tanks! I bought them in a bunch of colors! The fabric feels high quality. The shirt feels thick but not too heavy that it is too warm-it’s got a lightweight feel. The built in bra was high quality, thick enough, and covers all that needs to be covered. It holds me up nicely and is very comfortable. Also not cropped so it is a long enough length and appropriate for me to wear at work. The colors are all very accurate to what I expected. HOWEVER the white tank top was a bit see through so I returned that one. But I love every other color I bought!
Sharon Griffith –
Material is very thin. It does not have the structure to stay in place around the mid section. It will ride up and does even when not working out. Maybe ordering a smaller size would be better but the decrease in cup size and bust would most likely not work. I do like the fit through the bust but the straps seem to shift also. I wilk try another brand or possibly go back to lulu I just wanted a cheaper alternative. Color is fine but won’t be functional for workouts with the poor quality and craftsmanship.

I was a bit skeptical when I recieved these tank tops (bought one black and one white in size large) but when I put them on I was pleasantly surprised how comfortable they were! They fit perfectly on me. No back fat to be seen either! They will be great for summer as they are light, built in bra is honestly better for me for summer than a bra under a shirt. Sounds weird I know but I don’t sweat as much lol. I will be buying more of these! One thing I don’t understand is why the white was on sale for $19 amd the rest were $35-$80. The higher price was disappointing, so ill be looking for the sale ones

This is one of my favorite gym tops that I own. I am 5’3 117 lbs. and a petite/semi-athletic body type. I purchased the XS which is form fitting and hits me right at the bellybutton, which feels like the perfect cropped length. Good overall quality and the built in bra is supportive. I love the lime green color. I would definitely buy this in other colors when I’m ready for another top.
