"I love my Sumatra surf suit! It is so flattering, and I never, ever need to adjust it in the water."-Lindsay
Our best-selling Sumatra Surf Suit is designed for unmatched comfort, performance, and protection in and out of the water. Crafted from premium Italian recycled nylon and ECONYL® fabric, this eco-friendly, wetsuit-inspired design shields you from the sun, wind, and reef scrapes while delivering a sleek, second-skin fit.
The buttery-soft turtleneck and thumb loops ensure a snug, stay-put feel, so you can focus on the waves—not adjusting your gear. And because we know what surfers need, we’ve added an interior pocket to stash your surf wax or key.

I love the suit! The fabric feels lovely against the skin, dry or wet, and I adore that it has full coverage for the neck and hands. The bottom also usually stays in place while surfing-minimal adjustments needed. I am in between sizes S/M. 5’6”, 135 lbs 35” bust-35.5” hip which on the size chart is an extra small/small but I’m sometimes a medium often because of my frame. (Short waist but broad shoulders and long arms/legs) In the scorpion rash guard I got the medium and it fits well. For this surf suit small fits well around the bust and hip, but I probably could’ve used an extra half inch in the sleeve to fully cover the backs of my hands. The one concern I had was when I was doing the “shimmy” to get it over my hips I could hear stitches ripping in the waistband, so I worry about the quality and the top and bottom separating in the future. It fit great once it was on and was not restrictive, but sizing needs to take into account for a piece like this that it does have to go over your hips so the waist needs to be stretchy enough to make it over that part of you without self-destructing.
Also, a zipper “garage” or tab to keep the zipper in place would be useful. Without a keeper, the zipper tends to come open by a few teeth and then those teeth get caught in your hair so your head gets stuck for a second. It’s mainly annoying if you’re out on a rough day and turning your head often to check the incoming sets and your drift against the beach. A small annoyance and perhaps the price we pay for having good neck coverage, which is one of the reasons I bought this suit and not one of the other iterations out there. I would also be interested in a version of this suit that has legs that go down to below the knees to provide top of the thigh coverage while sitting on the board. (One of my aunts just passed from skin cancer, and while I still love the sun, I like to be in control of how much sun I get and also not have to slather on a bunch of sunscreen that won’t stay on in the water anyway!)
Ordered a L, need an XL, would recommend sizing up for this!!
I love my Sumatra surf suit! It is so flattering, and I never, ever need to adjust it in the water. I feel protected from the sun alll the way up to my neck and I can roll the sleeves up or down depending on how I'm feeling. It's just the right cut in the back. I forget I have it on and feel super confident and balanced on my board - the two layers of fabric don't slide around when I'm turning to catch a wave, as I've experienced with some other surf suits. So grateful to have found this - it is my daily companion in the water, so well made and looks great. Thank you, September!!
I luv e in Costa Rica and this suit is perfect for my sunrise surf sessions…and any of my surf sessions. I love it. It stays in place and it’s super comfortable. It fits really well.
The fit and coverage of this suit makes it perfect for surfing and playing on the beach. I love not having to worry as much about sun protection for my top be because the neck and and arms are covered. The material is soft and so comfortable. When surfing everything stays in place. And it's just a cute suit as well! It's my go to suit.
I love the color combo. It fits like a glove and looks so cute.
I have not taken this down to warm waters but will in a few weeks. can't wait to give it a try down in Baja in June.
Im pretty much in love with every suit I order from September.!!
Great colors and definitely quality material! The cut is super cute, but is for those with small torsos and larger bottom--like an hourglass figure--so take into consideration with sizing. I'm usually a small, but am returning because I would need a medium (5'5", ~130lbs, but I have a straight figure--bottoms fit great, but too small in waist and shoulders).
I’m on a surf trip in Indonesia and have been surfing in the Baja suit non-stop! My favorite thing about the design is that I haven’t had to adjust it AT ALL while surfing, even in big surf. The high neck is awesome for sun protection and the suit fits nice and snug.
I wore this suit on a surf trip to Baja and it was perfect for sun protection and surfing in 75 degree water. As a mom of 3 it’s hard to find a suit that is both flattering, functional and protective. I love the cut of the butt and the high neck. The material is also very high quality and doesn’t slip around while surfing. I’d buy this in every color!
This is now my summer staple. Feels very cool with the heat when it’s wet.
I’ve been wearing the Alaia surf suit from September, and it’s quickly become one of my go to surf pieces. The fabric is incredibly soft and comfortable, but what really sets it apart is how secure it feels in the water. Whether I’m paddling out, duck diving, or getting tossed around during a wipeout, this suit stays on. There’s no sliding, and no pulling down in the front when water rushes in during a duck dive. I also love the print it just makes me happy every time I put it on. September and Erika really nailed it with this one. I live in Costa Rica, and it’s perfect for shortboarding and made for real surf conditions.
Suit fits true to size and feels perfect in the Honolulu summer ocean! I hope it lasts forever!
Love the print and the fabric. Perfect for diving !
Great top, fits well and true to size. Super soft material. The print is vibrant and detailed. I surfed in it the other day. It was comfortable the whole time and stayed in place.
Great surf top! Fits true to size and is secure. I am a 34C and the S fits my bust well. I do wish the straps had a bit more elastic for extra support but very pleased with the overall fit, comfort, and functionality!
I have been a die hard Lucky Bottom girl for some time now! They are tried and true: Secure, supportive, and stay put so I don’t have to worry about any slips in the lineup. Fit is more moderate but very flattering; material is soft and buttery and very very comfortable. I have multiples of the bottom and while I can wear a XS or S - I will say I prefer the fit of the XS to ensure extra security, especially when wearing these bottoms in bigger waves of consequence. If you are between sizes, I would recommend sizing down!
This top is so good! Super comfy, supportive, and it actually stays in place when I’m surfing or just laying out. The fabric feels really nice and the fit is super flattering. Love the square neckline and the textured fabric. I’ve been reaching for this one nonstop. You can really tell the quality in the fabric!
I love this super cute suit! Double lined so it stays in place while I’m surfing. Awesome color pattern.
Pattern is so cute, fits perfectly, true to size and super Flattering, and for sure the most comfortable bikini i got. Cant wait to have some more September in my closet🌺
I adore this sun crop top/rash guard. The fabric is super soft (I have never tried anything near this soft), and it fits so nicely! Perfect for longer surf sessions in the tropics/during summer, to stay protected from the sun. I used to surf in bikinis only, but this top has been a total game changer now as I want to protect my skin more. The thumbhole detail helps to protect the upper parts of my hands too, and makes it stay in place. Can’t recommend it enough!! Love it!
Really liking to surf in this. The coverage is perfect for me, feels comfortable at all times, it’s buttery but also resistant. I’ve gotten compliments on the cool green pattern too!
This top is exactly what I needed for the right support and a comfortable yet stylish feel (my biggest fear with bikinis is to see my top fly off mid wipeout!). The fabric is very soft and the color is actually super vibrant, I’m definitely loving it.
I really love the fit of these surf shorts! They are high waisted and I love surfing in shorties like these. The color and material is also nice. The only thing I don't absolutely love is the banded elastic waist, just because sometimes it is not the most flattering if you are in between sizes. Mine are really comfy and fit me well, I am a pretty standard medium and they seem true to size. They stay put in the surf and I got lots of compliments on these :) would recommend.
I surfed in this top and its super cute and stays put! Usually I end up with the same style of sports bra - esque surf top because it's all that really stays on in the surf, but this one is flattering and I didn't have to re-adjust it either. I got lots of compliments on this! Personally I took the padding out, it's nice that you can remove it if you want. I also really love the blue color and the ribbed material feels nice. Very comfy.
