Tan-Through fabric
Regular swim blocks the sun and leaves a white line. Our open weave lets it through to your skin.
Regular swim
Tan-through
Still UV — wear SPF under the suit, like on bare skin.
Most swim fabric blocks UV. Ours is built around it. Microscopic air spaces in the weave let sunlight pass through to your skin, so you tan continuously — even with the bikini on. The same air-space structure makes the fabric dry 2× faster than regular swim and 7× faster than padded styles.
Tanning is a process that depends on a lot of factors including the sunlight intensity (UV index), your altitude, genetics, and skin type. Therefore, it is very individual. Wearing BetterTan for as long as you can will ensure better results.
Areas of your skin that have never been exposed to sun may not tan the same way as skin that has been exposed before. Pigmentation may differ and sensitivity levels may be higher. We recommend using an extra layer of sunscreen on those areas to avoid burning. You may also notice slower tanning in these spots.
Yes — we recommend wearing sunscreen to protect the skin from burning.
Of course. Our swimwear is long-lasting and fits perfectly onto any body shape, so you can use it as you would any regular bikini. The fabric has been tested in salt water and chlorine for durability.
Hand wash with lukewarm water. See the label attached for more detailed guidance.
Our straps are made very thin so they don't block the tan. Normally they don't interfere with tanning since they're made from the exact tan-through fabric as the rest of the bikini. We do recommend moving them around from time to time for the most even results.
Our bikinis are unlined (no padding) so nothing stands in the way of the sun's rays. The fabric is tested both dry and wet to ensure it isn't see-through. Some breast types may show more than others — if you'd like to reduce any potential sheerness, we recommend sizing up. (Sizing up may slightly reduce how much sun passes through the micro-perforations.)
