I bought 2; an extra small and small. I'm usually a small in t-shirts/tanks. I'm slim and a 34/36 A and both sag in the armpit area because i'm not chesty enough to fill it out. The XS worked a little better for me than the S but surprisingly not by much. This is quality, soft material so I only dinged it by 1 star since its fit is for a specific body type. If you are chesty, have broader shoulders or have bigger upper arms then this fit may work for you? I washed it and no shrinkage.

This tank is so soft, I really like how it fits, I purchased the white one and the material is high quality and solid so you cannot see through it, I will purchase more.

So soft and cozy! A nice loose, long tank perfect with leggings or side-tucked with jeans. Looks good with a bralette but can also be worn with a regular bra without it showing. I've got a few in different colors and love them all. It's supposed to have a loose relaxed fit at your regular size but size down if you like it more form-fitting.

Prana's foundation line is where it's at. The material is buttery soft and so comfortable. I wear this all summer long and will definitely be getting more. Does run a bit large. A small fits me pretty well and is on the baggier side.

I love this tank. It is soft and goes with anything. It is meant to run large, so no need to size up like I did!

This is a wonderful tank, feels great on....ordered a medium for a loose fit. I love the length.

I use this tank for yoga and it very light weight and soft. I am normally an XS in Prana shirts, but bought this in a small for a looser fit. The white is a bit see through, so I would buy a darker color if you have issues with your bra showing.,

The kind of shirt you want to wear all the time. This tank makes you realize how inferior your other tanks are. Nice cut, good coverage, no tugging, SOFT and lightweight. The lighter colors are somewhat see through but a medium or dark color is fine with a nude bra.

I like the fit of this tank. I can wear a regular bra underneath and the light gray color pairs well with colorful shorts and even in my "gravel" colored Tess shorts from Prana. My only issue, and this could just be the color I chose, is that it shows sweat extremely well. I get very sweaty in the summer. If you don't sweat than the light gray may work for you. Once returning to air conditioning the shirt dried fast. I may buy a different color since I like the shirt a lot. The material is very soft and it breathes well when I wore it sight seeing in Texas this summer. Medium fit me well, I am 145lbs, bra size 34D, 5'3".

This tank is nice and lightweight(but not too see through) and will be great for summer. I love the soft material and the longer length and it is easy to throw on and wear on a casual day, a hike, or whatever you are doing. I probably could have sized down it is a little loose but the small still fits.

This is a great basic to have in your closet. The material is soft and drapes nicely but isn't too clingy. The length is longer so it covers your bum and the pocket detail gives it a bit of interest. It's easily become one of my favorite tanks.

This tank is heaven...runs true to size I would say and not a clingy material. Ordering another color!

This tank is awesome!
Super soft, nice flowy fit, nice cover, great for any kind of activity. Does not show an outline of your bra, belly, or hips like some tanks. Dries quickly. I would buy it all colors!! There is a long sleeve version that I may buy too for colder days.

I have wore this tank camping a few days in a row. My backpack strap wrinkled the waist part a bit but it ended up falling out a couple hours later and still looked very clean after three days of wear :). I am always bummed when it is in my dirty hamper.

This tank is so comfortable and soft! It's hangs nicely and can be dressed up. I bought it in a size small and it fits great.

This is a great tank, it fits great, the fabric has a great drape and hand. I bought the grey, but it almost has a purple tinge to it in person. Would definitely recommend. Has good coverage - no bra straps hanging out. Took it on vacation and it was my go to tank!

I own two of these tanks, and two of the short-sleeve foundation tops! The material is fantastic! Super soft, light, and hangs really nicely. My only complaint with these tanks is that the arm holes are pretty large, enough that I wear a sports bra underneath. They are great for casual wear or even light hiking. I wouldn't say this is a technical fabric but I'd definitely chose it over cotton and most of my other casual tops for anything active or just being out and about in the heat! The pocket is a cute detail. I generally wash these on cold / gentle and hang dry, although I've accidentally dried one before and it didn't seem to shrink.

Fantastic material..doesn't wrinkle, washes beautifully, drapes wonderfully. Breathable fabric without bulk works exceptionally well for layering. Just returned from 3 weeks traveling, 2 of which were backpacking in Europe - this quickly became my "go-to" shirt.

Only complaint is the shirt runs large, especially at the armholes. Won't stop me from ordering in more colors, though!

I absolutely love this tank! The material is TO DIE FOR!! It's perfect to throw on with leggings to workout/yoga in and then I also would tie it up with high waisted shorts and loved it that way as well!! Very versatile!

Soft and lightweight fabric, but is cut in just the right way that the light fabric doesn't end up too clingy.

Perfect for summer, and for layering. A definitely go-to everyday kind of tank.

I ordered a Large and it was perfect. I generally wear a Large in prAna but an XL in most other brands. So sizing is true for prAna, but large comparatively.

This is great tank from Prana! It is comfortable, flowy and fits great. This is perfect as a stand alone tank for the summer or is light-weight enough to layer under a flannel. I cant have enough tank-tops and wear them constantly, this is a great addition to my current collection.
