One-Piece Swimsuit

Q: Are one piece swimsuits good for scuba diving?

Yes . Many divers prefer one piece swimsuits under a wetsuit because they provide secure coverage and reduce shifting during movement. A well-designed one piece stays streamlined and comfortable during dives, snorkeling, and long ocean days.

Q: Can I wear a one piece swimsuit under a wetsuit?

Absolutely. One piece swimsuits are often ideal under wetsuits because they minimize bulk and stay in place without riding up. They also offer added coverage and support during underwater movement.

⭐️⭐️⭐️⭐️⭐️ - "Super comfortable stretchy fabric, not at all see-through & covers in all the right places"

Not all one piece swimsuits are designed for real ocean movement.

Are your one piece swimsuits sustainable?

Our one piece swimsuits are made using high-quality recycled fabrics for all US production and are produced on demand to reduce textile waste and overproduction. By choosing durable, recycled materials, we significantly lower environmental impact compared to traditional fast fashion swimwear.

*EU production does not use recycled materials at this time

Will these hold up in saltwater and sun?

Yes. Our one pieces are designed for repeated ocean use. The fabrics are durable, chlorine-resistant, and built to maintain their shape and color through saltwater exposure and travel.

We recommend hand washing in cold water to prolong the life of the fabrics.

Why choose a quality one piece over fast fashion?

Higher-quality swimwear lasts longer, performs better underwater, and reduces the need for frequent replacements. Investing in durable, sustainable pieces helps reduce textile waste and supports more responsible ocean-conscious choices.

Do your one piece swimsuits provide sun protection?

Our swimwear offers coverage and can help reduce sun exposure. For extended sun protection, we recommend pairing your suit with a UPF 50+ rash guard for additional protection while diving or spending long hours in the water.

Fits under my wetsuit

Beautiful wish was a little longer to cover my stomach

Wonderful

I got this suit after many disappointing suits. This one fits well, feels secure, and doesn’t have cups or squeezing fabric or any of that stuff you don’t want when you’re diving. Can’t wait to get it in the ocean. For fit, I am 5’2” and 180 lbs.

This bikini fits my girlfriend so well it's poetry:
Waves lap, splash her curves
Ocean Serene bikini
Happy Wet Woman!

I would strongly recommend this bikini as a gift to anyone hoping to convince their girlfriend to move to the Caribbean to live, work, and play by the sea. Not just because of the robust construction of the swimsuit, but because of the excellent customer service experience you're in for with Andrea/The Dive Compass.

I'm obsessed with this new print

I love the colors, pattern, and the fit of this bikini! 10/10

Such a cute design! The fit is perfectly!

Perfect bottoms for diving!

I’m obsessed with my whale shark bikini! 🐋💙 The fabric is so soft, the fit is amazing, and it gives the perfect amount of support. I felt incredibly cute and confident wearing it — it covers exactly where it needs to while still feeling sexy and cute. Perfect for diving or just a beach day ! It’s easily my new favorite bikini! 🌊✨ Lo amo!!!

I love this swimsuit! It’s great quality

Very nice design and material. For diving in warm waters or under the wetsuit - but it's too cute to hide it ;-) The size runs quite big, you could choose the smaller one.

I love the bikini top. It's so comfortable, top quality and the design is very cute. I wear it with a normal black bottom and it looks very nice together.

Love the quality and design! So unique and fits great.

Beautiful! The quality and unique design are just what I needed. I love diving and wanted a rash guard that was not the typical mass produced look. I bought this design and love it so much, I will be on the lookout for new styles from this company. Awesome quality and comfortable too! Love it!

My favorite purchase as the fit is good and the print is pretty!

Comfortable, loose fit and awesome prints.

Pretty print! I think these will fit well under a wet suit. Take your time to really measure yourselves before ordering!

Very pretty and good quality top! Don't have a photo yet as I've not gone diving with it, but soon!

This is my third diving bikini I've purchased from the dive compass and I can't get enough!

I absolutely love these Bikinis! I'm stocking up for my liveabord in Egypt!

I am obsessed!!! This suit is sooo soft and so cute!!

This is a perfect rash guard!! Exactly what I was hoping for. It fit perfectly, is so well made and great quality material, protected me from the sun and sea critters, and looks so great!! Perfect for snorkeling or diving or any other water activity. Got tons of compliments and everyone kept asking me where I got it!! Was thrilled to tell them about this company, which donates 10% to ocean conservation! Will definitely be buying more!
