Patagonia Women's Reversible Seaglass Bay Bikini Top

Super cute top! Size up!!

I got this top for swimming, kayaking and snorkeling. I like how it fits. I typically would buy a medium and have a medium in most bathing suit tops from Patagonia and other places, but I decided to size up based on the reviews and I am glad I did!! I typically am a 34C or 34D if that helps!

Love this top.

I love this top because there are no ties or clasps. It's great for kayaking.

Flattering, Stay-put suit

I love this line of suits. Im an active and fit 46 year old and find suit shopping tough. I dont want it to be super revealing but am bot ready for an old lady suit yet;). This suit gives me the perfect amount of coverage while staying put in the waves! And I LOVE the flower pattern. Well done Patagonia!

Fun little top

Bought this to lounge on vacation in the BVI's. Very comfy, and held up well in my daily snorkels and swims.

March 17, 2021

So cute!

This top is really cute and flattering! It does run extremely small- I'm a 36D and usually a medium in Patagonia clothes and the XL fit me snugly.

Zero support, but very comfortable

I'm on the fence whether to return this top or not. On the one hand, it's the most comfortable swim suit top I have, but on the other, it's not very flattering unless you need no support. Worth a try if you aren't picky about support.

February 27, 2021

Super cute too

Bought this top in white. One side of the suit is ribbed and the other reversible side is smooth. The back is super cute and different. This suit definitely runs small. Im petite and small chested. I read other reviews and sized up so it fits well.

February 21, 2021

Comfortably and functional

This bikini top is super cute and stays in place. Im 510 and wear a 36D bra. This top fits perfect and I love the reversible option. If you are looking for a top for a day at the river or wanting something to keep your ladies in place for a surf afternoon I recommend the seaglass bay bikini top. Get two if you can. You wont be disappointed.

Stays put!

Happy with purchase- like the colors. Lil tricky to get in and straps right but then no worries- stays where it should. I probably couldve ordered a size up for better coverage/comfier fit but got a medium- seems to run a tad on the small side.

When You Just Want A Good Old Fashion Bathing Suit Top!

Perfect for Hawaii and the pool, bought 3 colors and they are reversible so it's like having 6 new tops to swim in :)

September 27, 2020

Love the color

I really love how this top fits like a sports bra but doesnt look like one. The green/blue combo is so pretty. The only problem I have with it is the straps are not adjustable and I could see them stretching out a little too much in the water.

Cute! Runs small

Im about 53, 115 lbs, 32C, and I normally buy smalls in Patagonia swim tops, but this one was pretty tight! I like stuff to be secure for swimming and being active, but I dont like to squish my back fat between straps, so I sized up to an M. Its better but slightly too big, but Ill take it.

Thanks for taking the time to provide a detailed review with the fit and your sizes. Enjoy your time in the water.

Best swim top

Once you understand that you should size up best fitting top. I wear a 34A bra. But, I have broader shoulders and upper back. I would typically wear a size small. I went with a medium after reading reviews. The cup size is perfect for an A. This top doesn't ride up. The straps can be adjusted narrowly or widely. Love this top. Use for swimming...

I like the fit and athletic feel. Looks good too

Sexy back!

Fantastic for any water sports. Excellent support and back straps quite sexy. Am a 34/35 B cup with a broad swimmers back and ordered size Med. Perfect fit. Originally ordered a Sm and it was OK.

Very tight, runs small

I'm usually a small or medium on top and am a 34B and this mashed my breasts and bound tightly in the back. Based on my experience with the bottoms and top these run 2x small compared to other athletic brands

Great bikini

I honestly love this Bikini, it was a great price point being that its also reversible. The size is perfect, I havent had a bathing suit fit this well in years. Super comfortable and the lime green color is beautiful. Really happy with my purchase.

September 4, 2020

Swim Suits Fit Weird

I love Patagonia products and I really want to love the bikinis, but I dont. They all fit weird. They are too tight and then dont look flattering at all. I am super fit and very low body fat so any bikini should look good. I am 55 and 123 lbs. I ended up going with a medium size. Not sure that I will keep it though, for the price.

September 2, 2020

Outstanding quality

I bought two of these for my daughter in different colors. I am always hrilled with the quality and so is she. She's happy and I am happy with the cut and fit. Patagonia is our go-to brand for many things, including swimsuits!

September 2, 2020

Love this for!

I wear a 32DD in bra size. It fits perfect, stays on tight but is really comfortable. I have it in 3 colors now.

September 1, 2020

Order one size up

I usually get a size Small in bathing suits. But this one fit so tighly I could barely breath. I returned and got a Medium. The medium fits me snugly.

Great suit. Runs Small!

Overall the suit is fabulous. The style is spot on. Cute and functional. Runs very small. I am usually a Medium and needed to return for XL.

Lightweight Support

Liked the top/design so much that I ended up getting second one. This top offers lightweight support without padding. The simple design is flattering and functional; love that its reversible too.

August 7, 2020


Comfortable- straps can be distributed for a perfect fit, and easy to get on. Reversible too, which is a bonus. I use weekly for kayaking + climbing days at the local reservoir.

July 16, 2020

Very good

I was very skeptical, i'm 34D (135 lbs) and wasn't sure this top will fit ok. But it did! I tried both M and L sizes. L provides better coverage, but straps were way too loose. I decided to keep M, it's super comfortable, provides enough support. Maybe little revealing, but it looks great.

Im so glad I bought this top!! Its so flattering if you have an average sized chest and offers a lot of lift and support. It holds the girls in place during beach activities or swimming in the ocean.

All day comfort for a B cup small frame

This top is about as close to a bareback feeling as anything. It is easy to put on, it stays in place and provides enough support for a B cup. It dries quickly and doesnt soak up extra water given the perfect lack of padding. The back straps stay in place yet are easy to move around if you want to prevent tan lines.

stays in place

I swim casually in a pool. The suit stays in place when I roughhouse with my son. Never do I tug it or adjust it. The only trouble is getting the contraption on if I'm already sweaty or off when I'm still wet. It's like a thousand rubber bands, but I do really like it.

June 17, 2020

swimming and kayaking

Love the design, and it stays in place while swimming and kayaking. Only wish the cups were a tad bit bigger. My ribs are to small for a large but my boobs are almost to big for the medium, I wear 34c.

June 17, 2020

Snug fit for water sports

Bought for swimming - fits close and snug - good for water sports....

I really enjoyed the swimsuit

I really enjoyed the swimsuit top.

November 27, 2019


Fits perfectly and is easily the most comfortable bikini top I've ever owned. Love the double sides, and works for me, but be weary there is just double lining, no padding. Very flattering, comfortable, and holds everything in place. I'm a 34C and got a medium. Will probably be getting more in other colors!

November 22, 2019

The top is a tighter

The top is a tighter fit than I’d expect for a small. The bottom fits perfect. The small straps hurt a bit.. I’m generally a 2-4 for size. The medium would be too big but the small is too tight.. disappointed.

Stays Put and SO Much Better For Neck

Really grateful I scored this top on sale. I refuse to wear swim tops that tie behind the neck. Hurts too much! I own a couple older pairs of Patagonia swim tops that go around the shoulders and tie in the back. Much better on the neck. But a pain to have to tie and adjust if I worry it coming untied. This Reversible Seaglass Bay Bikini top is a re... Read Moreal saver in all aspects! Not around the neck AND no tying needed! I am 5'1 and 95lbs and flat-chested. Got size XS. It fits super snug (maybe a little too tight - but no complaints!) which is good for swimming/surfing. I like how the crisscross straps in back/around shoulders all stay put. I have owned a similar style (not Patagonia) and the straps were all loose and weird. Not this one! Didn't worry about color choice - was just stoked to score on sale. Ended up with the Lavender one - pleasant print. Can't go wrong with this top! I'm sure the matching bottoms are great too!

November 13, 2019

Favorite swim top!

Wear this for everything: swimming laps, beaching, rafting. Works like a really cute sports bra, granted I'm 34A.

Love the prints, love the color, it's double the fun. The cut us cute - athletic and sexy. While I haven't tested it out in the water yet, it feels like it will stay in place.

Overall great top

Love the material and the fact that this top is reversible. However, as others have commented, the size runs small (I am usually a size M in bikini tops - sometimes a size S - so I ordered an M and it’s borderline too small). The straps on the lower back kind of cut into my lats (as another reviewer also mentioned). I think it will stretch out a bi... Read Moret though, so I’m going to keep it.

Seaglass bay top

Love these tops. Excellent fit, excellent quality. I turned around and ordered more.

September 23, 2019

Sporty and sexy suit

I love both my Cliff Cruiser Seaglass tops. They are supportive and sexy when I take runs on the wakesurf or quiet sessions on the SUP. I’m just sad I bought them late in the summer! I can’t wait to enjoy them in more warm weather next year!

September 19, 2019

Love Patagonia bathing suits

They are so worth the money. They stay on, and are well made, and look cute! :) Only complaint is the sticker they use for hygiene on the bottoms...way too sticky and it leaves a sticky residue on the bottoms which is annoying until it wears off. I recommend they change it

September 18, 2019

Perfect for surf

I love this top for surfing- I usually wear a rash guard or some type of wetsuit- it’s easy to quick change - but the it did take practice 😉 I wear a Medium and I’m a 32D

Thankfully it came out but I thought my new suit was ruined when I first took it off and saw the sticky residue. If that happens to you run the bottoms under cool water and use your nails to scrap it off... hopefully Patagonia starts using different hygiene pads.

September 12, 2019

Nice top

Was a little hesitant in choosing this top as the girls are a hefty C cup. Wore this rafting and kayaking without falling out. A little over spilling, but just enough to look great.

September 11, 2019

Very comfortable

Not super tight, but I don't have to adjust this top, even as I play beach volleyball. The straps are not adjustable, which could be a problem for some, but I like that there are no bulky knots to deal with. I wear 32B, and the small fit me perfectly.

September 10, 2019

Really comfortable and functional

I love how comfortable these are to wear and that they feel secure for surfing and playing in the ocean. They work so much better for me than the Kupala tops which tend to ride up my front and look terrible. The only thing about these tops are that they probably make my flat chest look even flatter.

September 9, 2019

Cute as heck but size up if you got a back

Love this suit, soft, comfortable af, no pads to get waterlogged with! Everything I could have ever wanted, the only issue is my body. Im 5'9 ~170lbs, 36C and pretty broad shoulders.

Just what I wanted

This top is great — full coverage, fair support for moderate swimming but no struggles getting it on. But what I love most is no knot to dig into my back when I lie on the beach to dry off afterward.

Practical Functional Comfortable

Stylish and functional bikini top. Comfortable yet stays in place no matter what you are doing. I have no problem figuring out how to put in on. Bonus: reversible so you get two colors.

Best Top Ever!

This top is by far my favorite! It is super attractive and flattering AND amazing support!!! The perfect combo. It stays on even playing in the waves. I wear a 30D cup and bought an XS in the suit, and love the fit.

Great swim top for all summer adventures

I have worn this top multiple days a week this summer and love it. Good coverage, stays in place during paddling, swimming, rope swinging, water park adventuring.

Great look, poor performance

I love the way this top looks. It’s athletic but without big straps (aka less chunky tan lines)—but the straps aren’t really functional. I have an athletic build without much to hold up, and I still felt super unsupported.

It actually fits! I always wind up returning stuff when I order online, but this fits!

Very comfortable, minimal coverage

I got this specifically to wear underneath my quick-dry shirts when paddling my boat. I did not want any water-sucking padding. It has been supremely comfortable to wear all day.

July 5, 2019

Nice - but no lining!

This is a nice top. It runs a little small; I'd suggest sizing up if you're on the fence. But be aware there are no removable cup liners, unlike most Patagonia swim tops - so this is not a good top for the modest, especially when the water is cold.

June 16, 2019

Wanted to love it

This top appears to be the updated version of the mamala top which I loved. The back on this cuts into your lats. The way the straps are positioned cut right under your scapula's and really cut in.

Stays put

The swim top worked well and didn't move while snorkleing and jumping off of high places into deep water. I also wore it instead of a sports bra while running and cycling. I prefer a little more coverage and although I like the visual of the straps it was difficult to get on and off while wet or while sweaty.

Not Enough Coverage for Me! (32DDD)

The overall fit of this swim top was great around the body (bought a Medium), but the coverage itself was minimal. I am a 32DDD and thought maybe I could swing it (it looks great on the model), but I was just too exposed. Would recommend to my smaller-chested friends!

Fits perfectly

This suit fits me just perfectly. It is secure and I don't find myself monkeying/adjusting things. The strap design is neat that it does not dig into your traps. I'm 115# 30 band size, c cup and the small fits well. The rouching in the front is a nice touch. Highly recommend!! (Also, this top looks great with the Telu bottoms- not sure if...

Best bathing suit top ever!

I have this bathing suit in both black and blue. It is awesome. It doesn't move! I wear for kiteboarding, wake boarding, and swimming with kids. I'm 5'8" and weight 157 pounds and the large fits great. Please make more colors next year bc I want to buy more!

Pretty good but not perfect

I am on the constant hunt for a swim top that is simple; simple lines,but looks good and is no fuss (hate adjusting,worrying about falling off,or dealing with curly ends of tie straps),can fit seamlessly under a shirt without bulk,and can be worn for active water sports. This meets all of those needs. My only issue is with fit. The material is grea... Read Moret and soft and pretty. I am usually a 34B,measurements are 35.5 bust and 33 rib cage/band size. I tried the small and could barely get it on. The medium is nice but still digs slightly in the band. I think the large could work but then maybe the cups would be too big- the fit of the medium is very nice looking for the ladies. I'm keeping the medium and hoping the band stretches a little,especially after being worn swimming. Wish the strap design were simpler too,but hey its the best I can find! I also love this company so prefer to buy a top here than from competitors. Hope this helps!

I can't say how much I love this top. So glad I tried it! It is minimal but amazing. No pads,no problem. Double layer fabric and styled to uplift and support.
