Higher compression but so comfy

Love it but not light colors
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!

My favourite workout tank - have it in multiple colours!
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.

Comfortable
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.

Pills like crazy!
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.

It's fine
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.

Lovely but small
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 but poor quality
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.

Comfy, not very suportive
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.
