You love going out for a run but global warming has made it impossible for you to run more than half a mile without being drenched in sweat so you rather spend the summer in the pool. What if you could go running and swimming without having to change? Well, maybe just not your top and after you wash off all that sweat off of course. Aha, a racer-back version of our very popular Flatsea is here for you! The neckline is cut slightly lower and it’s longer than the Flatsea, available in three amazing compression levels.
- Fully lined
- 16″ long from bottom of armhole seam to bottom seam
- racer back cut
- Machine wash in cold water
- Imported

Description
The Flatriver, a racer back version of our very popular Flatsea, the Flatriver is a product we came up with after listening to all your comments and suggestions. The neckline is slightly lower than the Flatsea but still high enough to cover any cleavage. The closely cut armholes protect you from possible side skin but are more open due to the racer back cut. The Flatriver is longer, a total of 16″ long measured from the bottom of the armholes to the hem line (based on a size Medium, may vary depending on size). This fully lined top comes in low compression, high compression, or no compression at all. Available in black, navy blue, and grey.
When picking a size, we recommend you use our size chart for guidance. Our sizes aren’t exactly like other traditional clothing brand sizes. If you’re looking for maximum compression and you fall between sizes, we recommend you go with the smaller size.
Remember Outplay compression tops are not binders, they are made to be active in so they do stretch. For more information on how we create the compression, check out this post. Our compression swim tops can be worn for long periods of time, in and out of the water.

Compression
Designed & Made to Fit You
We’ve designed and created our unique compression swim tops for anyone who wants to hold, flatten, compress, or just be comfortable.
Our Compression Levels
No Compression
Looks and feels like any other swimwear. No compression fabrics are used.
Low Compression
Helps with support and flattens lightly. It has a layer of our uniquely developed compressing material in the front between the outer layer & the lining.
High Compression
Helps with support & flattening capabilities are stronger. It has a layer of our uniquely developed compressing material added in both the front and the back of the top between the outer later & the lining.
No Compression
This option fits and feels like any other swimwear. There are no compressing materials used
.
Low Compression
The front of the top is made up of 3 layers of different materials; the outer spandex fabric, a special mesh-like material in the center, and the lining. The back of the top consists only of the outer spandex fabric and the lining of the top. The special mesh-like material in between the layers in the front of the top creates light compression over the entire front of the top
High Compression
The entire top is composed of 3 layers throughout the front and back. They consist of the outer layer of spandex, the mesh-like material that creates the compression, and the lining. When a high compression top fits snug, the compressing material in both the front and the back of the top create a strong hold through out the length of the top.

The racer back Flatriver is quite awesome! I have the Flatsea and this is a great improvement on the flexibility with the addition of the racer back cut and the black lining (rather than the white) makes it less obvious when edges flip occasionally. The biggest drawback is the color (maybe caused by the different lining?). I purchased this in navy and the Tomboiers in navy (Tomboiers have white lining) and the colors look nothing alike (this is especially apparent in natural sunlight). It looks like I mixed and matched from completely different companies. Otherwise, I recommend the pairing – great comfort and great coverage.

This top is aesthetically great! I love the androgynous cut and racerback! I ordered a large and it may have been a little big on me, but I felt like the “high compression” wasn’t at all compressive. It felt a bit like I was wearing a stretchy and heavy tank top. Thankfully, I happened to have a compression sports bra that aligns with the back of the flatriver so the flatness isn’t a problem. I love the concept and the look of the product, but higher compression is a must (especially for larger-chested people).

I really love this product. I am an almost 50 year old cisdyke who made a baby in my body and fed her with my boobs. I love that I can look and feel like myself — pretty much like a teenage boy — while doing all my favorite summer activities like running, kayaking, biking, SUP, and swimming.
I am looking forward to purchasing a Swimmee this summer. The Flatriver is a little heavy so it will be nice to have the shorter version for the hottest days or for wearing under a rashguard.

I’m busty and short. I’m a d cup and went for a medium with the low compression. I love the material, I love the cut, this is the first time I’ve ever felt truly comfortable in a swimsuit. My only issue with this is that the next is a little high I just put a little slit in the collar so I don’t choke myself. The next one I’ll get will be the high compression just because of my big boobies.

I love this top, I have two in high compression, as well as the Flatsea in both high and low compression. This top has a slightly longer hem than the Flatsea and the increased shoulder flexibility is nice. The only reason I’m not giving 5 stars is because I frequently get trapped in this top when it’s wet and my partner has to release me. I have been trapped so many times that I actually prefer to wear my Flatsea top if alone. On the other hand I LOVE the lovely shiny soft fabric
