TnaBUTTER™ Bound Sports Tank

Not only does it fit perfectly, it feels amazing! Normally wear a S or M but I’m a bit heavier in bust area so I with M. Perfect fit!

Love the soft fabric of this tank top and I love that it has a built in shelf bra. Aritzia design team needs to make this top in more colours! I purchased a small and my bra size is 34B.

I'm usually a small in tops but got this in a medium for comfort. I'm 34B/32C with muscular lats. For reference, I wear 8 in the Lululemon align tank. The support and level cleavage on this is perfect for me. I love throwing it on and not needing a bra! The fabric is great. I have 3 of these now

The quality and feel of this tank is A+ and the construction is beautiful! Nice substantial feel and so soft and comfy. I’m so glad I went up a size- I have a small rib cage and am typically an XS in everything, especially for tanks. I’m 5’6, about 115 lbs and probably wouldn’t have been able to get the XS on. The small is very snug on me. Consider sizing up, especially if you have bigger ‘girls’!

I thought this would be the same as previous year's tank, but it is not. The fabric is much much tighter (size XS last year vs. M this year) and not as stretchy/breathable.

Super cute and stylish for the gym or even just a casual outfit. It is a tighter fit but it makes your boobs look great!

I like the soft fabric and color (pink berry). The straps could be shorter and the bra elastic was too tight causing bumping on my back. Overall still fits and I’ll keep wearing it. I maybe shorten my own straps.

The material of the top is so soft, I wanted to love these tops but the fit would be impractical for a workout, not enough support in either the small or medium sizes. I wear a 34D/DD for reference!

Too big, but was soft and overall really nice. But unwearable as it is too big and doesn’t sit right, nor does it look right.

Fit is amazing and the length is perfect! Just need more variety of colours. All the colours available is either out of stock or very muted.

I ordered a size medium in this top and it fits really good. It’s supportive and very comfortable. A great top for wearing to workout.

I am usually an x-small. The x-small is a tight fit to get on but once it is on, it is not uncomfortable and I like the support.

The tank is breathable and the perfect fit for a workout, I love the built in bra

Petite girl, 100 pounds 32DD. Could not breathe in the XS!! the waist part is fine but the sports bra is SO tight and restrictive theres almost 0 stretch. Definitely size up

This top is so flattering! I am 5’5, 140lbs, and ~ a 32D and the small fits well. I ended up getting this in two colors and I have a third in my shopping cart. This hits right at your bellybutton so it works perfect with high waisted leggings.

need one in every color, the fit is so good. Fabric is soft but durable. Great support

Awesome material, flattering shirt - however, definitely size up! As someone with a small chest, I still found this too tight in my chest area. Going to return my regular small for a medium and hope for the best.

I usually wear a small, but this was sooo tight. As a comfy top, I didn't expect it to be so restrictive.

Makes boobs look SO GOOD. material is so soft and stretchy but won’t pill like align stuff

This tank is very soft and gives good support. I only took a star off because there is something weird about the fit in the chest area that is very unflattering. I kept it though because I like having decent support. I think it’s made for smaller chested women as I tried XL and that was just too big around the band

Love this shirt so much, I always get compliments when I wear it

I take the pads out of these and I have it in probably 6 colours. My go to all summer, great for working out or casual wear

I first bought this in ashy pink and loved it. The fabric is amazing and it stayed put through my whole workout and so comfortable. Ordered another one in birch and the entire top is double layered in the same fabric and just trying it on inside it felt so warm and thick. I can’t imagine wearing it to work out where I’m already sweating buckets. Besides being too hot the extra fabric just ruins the sleek second skin feel and comfort. Since there’s already a bra with padding it’s completely unnecessary to double layer the entire body just because it’s a light color. Please change this!

Absolutely my fave workout tank - own it in multiple colours and it's my go-to for both gym and yoga. It definitely has that "barely there" feel and I LOVE how it doesn't ride up at all - which I find Lululemon crops do, and that's why I've switched to TNA. Unlike other reviewers I find this tank top is true to size. I wanted full coverage (no cleavage) but still fitted so I wear the size medium. I did try on the small and liked the look as well, if you are looking for a tighter look with more cleavage.

This tank is wonderful. I'm glad there is padding. There was pilling after one wear. Also, beware if you have a chest larger then 38DD ... They put more material width wise but they do not put more material lengthwise resulting in more cleavage showing and chest spilling out.

I absolutely loved this shirt when I first bought it, but I’m super disappointed in the quality. Pilled terribly after 2-3 casual wears - I wasn’t even working out in it, just wearing it around!

Quality is really not worth the price. You’d be much better off spending this amount at a place like lululemon for a sport bra/top combo that will actually last more than a few wears.

Comparing to the "muscle tank" - one of my favourites right now - the sports tops with the built-in bras & removable cups have fabric that feels thicker and less pliable. This results in the sports tops feeling like they fit a bit smaller in comparison (since they stretch less and have a 'harder' elastic band around the chest).
I do really like that the top has removable cups, since that's pretty much my main criteria for if a top can be worn without a bra underneath.

Perfect fit and buttery soft

The fabric is very nice and doesn’t get sticky when you sweat but it does run small. For reference I’m 5’3, 140lbs, 34 C and my normal size is medium but I have to order a large.

Cute tank, however, poor quality and there is little to no support making it inappropriate to work out in if you are above a B cup. The shirt pilled after ONE wash and generally feels cheap, not worth the money in this material.

I wear it to go on my morning walk with a t shirt/ or my pilates at home. I wear 34B/C and it 100% shows whats there. But its super comfortable and I love wearing it at home.
