Nice quality, some shipping delay

I ordered a high waisted bikini bottom and a bandeau swim top during a seasonal sale. The quality of the recycled nylon swimwear was excellent, very soft and comfortable. However, shipping took 8 days to reach California, which was a bit longer than I expected given I paid for standard shipping. Customer service was helpful when I inquired about the delay, though. Overall, a good experience, but delivery could be faster.

Good value with the discount

I was looking for a new swimsuit and decided to try Kalena Kai, especially since I found a newsletter sign up offer for 10% off. I bought a ribbed swimwear one-piece. The price felt fair after the discount. Shipping took a little over a week, but it was free over $150, which helped. The quality seems good for what I paid. I probably wouldn't have bought it at full price, but the offer made it worth it for a first-time buyer like me.

Good bikini, fast shipping

I bought a solid color swimwear top. It arrived quickly, within 3 days. The fabric felt nice and the fit was true to size. I would order again.

Love my new swimsuit!

I just got my new biodegradable bikini set and I absolutely adore it! The fabric feels so luxurious and the fit is perfect. I was so excited to find a brand that combines sustainability with such stylish designs. It arrived so quickly too, which was a pleasant surprise. I can't wait to wear this all summer. I'm already looking at other pieces for my next order. You really can't go wrong with Kalena Kai!

Really liked my one piece

So, I got this cut out one piece a couple weeks ago. It's actually really cute and fit well, which is always a gamble online. I was a bit worried about the 'biodegradable' part, like if it would fall apart, but it feels super durable. Wore it to the beach last weekend, and it held up great. Definitely happy with it, seemed like a good purchase.

Consistent quality, returning customer

This was my third purchase from Kalena Kai. I ordered a floral print bikini this time. Like my previous orders (a cheeky one piece and some luxury beach coverups), the quality was consistent. The fit was good, just as expected based on their size guide. Shipping was standard, about a week. It's why I keep coming back; I know what to expect and they deliver good, sustainable pieces every time.

They pretty much always have a newsletter signup discount, like 10-15% off. And around holidays like Memorial Day or Labor Day, they sometimes do bigger site-wide sales, saw one for 20% last year.

how do I know their swimwear is actually 'biodegradable'? seems kinda wild for a bikini.

S Steve F. 1 month ago
They explain it on their site, it's a special kind of yarn that breaks down in anaerobic environments like landfills or compost.

Yeah, it's made from a specific type of nylon that's designed to break down faster. It's not like it'll disintegrate in your closet, but in the right conditions, it's supposed to. Pretty cool tech.

Thinking about getting a Kalena Kai suit, but also looking at Frankies Bikinis. Anyone have both and can compare the quality or feel?

J Jared Osei 2 weeks ago
Kalena Kai feels way more luxurious and the fabric is softer, like really nice. Frankies is cute but sometimes the quality feels a bit less, if that makes sense.

I own both! Kalena Kai's fabric is thicker and feels more substantial, definitely holds up well. Frankies are good for trendy stuff but the Kalena Kai pieces feel more like an investment.

I'm usually a small in most swimwear, sometimes a medium. how does Kalena Kai sizing run? should I size up or down for the one-piece?

P Paula Doyle 3 weeks ago
i found them pretty true to size, maybe a tiny bit snug if you're between sizes. I'd go with the medium just to be safe.

My high-waisted bottoms were spot on for my usual size. I'd check their size chart but my experience was that they fit as expected, not too small or big.
