Sustainable swimwear from REI. Swimsuit season is almost upon us! I for one cannot wait. I have daily visions of relaxing on the beach (wearing sunscreen cause you know, important!), listening to the waves, sipping on something icy and delicious, doesn’t that sound amazing! After this cold rainy winter, my soul needs a little sun… as do my legs… they are pretty pale.

REI isn’t necessarily the first place I think of for swimsuit shopping. My mind drifts more towards all of the camping equipment and hiking gear you could possibly dream up and more, but they have a lot of really cute swimwear options! So, I wanted to put together a list of all the swimsuits from REI that I think would be perfect additions to your summer water shenanigans.

Shopping sustainably at REI is super easy! I’ve mentioned before in my affordable and ethical activewear post that they have a filter option for sustainable shopping. You can filter for recycled materials, fair trade, organic materials, and Bluesign certified products. I love this option as it makes sustainable shopping so much easier! All of the swimsuits in this post contain recycled materials and several are Fair Trade Certified.

One-Piece Swimsuits

Nani Swimwear Rip Curve One-Piece Swimsuit

I purchased this swimsuit myself and I love it! I actually didn’t know that it had pockets when I bought it. When I got and tried it on I was like, “What, this has pockets!?! This is so cool. Why wasn’t that advertised?” I looked back on the website and I obviously did not look too hard at the photo or product description because it definitely was advertised!

The cute floral print and colors of this swimsuit are so sweet. The cutouts are super fun and the high-waist bottom half is really flattering. This swimsuit has full bum coverage. For reference my sizes are 5’3″, 135 lb, 34B, and I am fuller in the hip and bum region. I ordered a size small and it fits perfectly. This swimsuit is $95.

Nani Swimwear Cascade One-Piece Swimsuit

This is such a fun swimsuit! Nani makes some really cute swimwear! The colors are perfect for summer and the one shoulder strap and cutout are super stylish. This swimsuit would also make a great bodysuit. Throw on a pair of cutoff denim shorts and some sandals and you’re good to go. So cute! This swimsuit is $95.

VOLCOM Simply Seamless One-Piece Swimsuit

You can’t go wrong with this classic black swimsuit. This one is really cute with the side cutouts and would also look great under some jeans. Full bum coverage per the description. This swimsuit is $110.

Swimwear Sets

prAna Ulana Swimsuit Top + prAna Tekena Swimsuit Bottoms

The bold geometric print on this suit is really cool! I love the braiding detail on the side of the bottoms and the top looks like it would be really supportive. The top and bottom are both on sale from $60 to $44.99 each.

Nani Swimwear One Shoulder Crop Swimsuit Top + Nani Swimwear Pocket Swimsuit Bottoms

OK, Nani Swimwear makes some seriously cute swimsuits! How awesome is it that they design them with pockets!?! The top of this swimsuit is so pretty. I love the wrap effect and the one shoulder. The pattern is really pretty too! The top is $60 and the bottoms are $40.

Seea Isabel Swimsuit Top + Seea Isabel High-Waist Swimsuit Bottoms

Such an adorable bikini from Seea. Love the bright sea foam color and the flutter detailing on the top and bottom. The top is currently on sale for $47.83 marked down from $80 and the bottoms are on sale for $50.83, normally $85.

prAna Ella Swimsuit Top + prAna Sul Swimsuit Bottoms

I love the pattern of this prAna bikini. This top looks like it would be very supportive and I like the hipster cut of the bottoms with the cute little braiding detail. The top is regularly $65 but is on sale for $48.69. The bottom is regularly $60 but in sale for $44.99.

Mix and Match Pieces

prAna Millan High Waist Swimsuit Bottoms

You could match this staple prAna high waist bikini bottom with almost anything. Pair it with a black bikini top for a cohesive set or play around with different colors and patterns. I think the high waist, retro look is charming and flattering. This bottom comes in two other colors/prints. The two solid colors are normally $60 but currently on sale for $44.99, and the print is on sale for $35.83 in limited sizing.

Patagonia Sunamee Swimsuit Bottoms

The Sunamee style bottom from Patagonia comes in tons of colors and other prints. There is a basic black which you could pair with anything, but I really enjoy this tribal print with the jewel and earth-tone colors. This bottom would pair well with a solid navy top! This bottom is $37.73.

Nani Swimwear Side-Zip Swimsuit Bottoms

Product image for Tahoe Stripe

This is almost the same pattern as the one-piece Nani swimsuit, but with some different colors. REI doesn’t have the matching top that is shown in the other product pictures. But you could totally pair this with any neutral bikini top. Or you could pair it with the next top below. These bottoms are $45.

Nani Swimwear Switch V Crop Swimsuit Top

This swimsuit top is so cool! It’s so fun and creative and would make a perfect match for stripe bikini bottom above. They are not technically a set, but they come from the same brand so the color matching would be on point! This swimsuit looks like it would be super comfortable and would even look really cute worn as a crop top with a pair of shorts. Top is $60.

Seea Brasilia Reversible High-Waist Swimsuit Bottoms

I wish they had the matching top because I am totally feeling this tiki vibe! I love the orange and pink over the chocolate-y brown base. This bottom would also look great with another solid color top. However, if you are have-to-match kind of person (I am right there with ya), the matching top is available at I love it when bathing suits are reversible! Normally, I see them with a print on one side and a solid color on the other. I love that this has two fun prints. Both the top and bottom are $80 each.

VOLCOM Simply Solid V-Neck Swimsuit Top

I love the straps and braiding on this itty bitty bikini from Volcom. They really bring the basic bikini to a new level. The top is $42.50.

Patagonia Nanogrip Cutback Swimsuit Top

This black bikini top from Patagonia would be super easy to match with another suit. I love the sporty look of this top and the cutout in the back. This top is $79.

Patagonia Focal Point Swimsuit Top

Product image for Marble Pink

I think this bikini top would look really cute with the black high waist bottoms above. The solid pink would also pair well with many other prints and styles. This bikini top is $69.

Happy Shopping!

I hope that some of these lovely swimsuits have peeked your interest! I can’t wait for the first swim of the season so I can wear my sustainable swimsuit. Does anyone have any fun summer travelling plans this year? I would love to know your favorite summer getaway spots. I am craving a beach vacay!
