When you think of the best long-sleeve swimsuits, you probably think of a practical rash guard designed to keep you safe from water sport scrapes—and to provide an extra layer of sun protection (especially if it’s constructed with UPF fabric). While these are certainly advantages, we’ve seen a lot of innovation in this space.
Best Long-Sleeve Swimsuits 2023:
The best swimsuit brands are producing adorable surf-inspired one-piece swimsuits, trendy puff-sleeve silhouettes, and long-sleeve crop tops that pair perfectly with a high-waist bikini bottom, as well as two-piece versions that double as cover-ups-all of which you can rock even if you’re more of a beach reader than a kayaker.
Whether you like the athletic appearance or simply want more SPF, these long-sleeve, editor-approved suits are calling our names like the waves—and you can know we’ll be adding one to our poolside arsenal.
You don’t need to wear anything underneath your swimwear if your long-sleeve bathing suit has a built-in shelf bra or padding. Layer it over a bikini top intended for a larger bust if you want extra support.
Athleta Sun Shield One-Piece Rash Guard
This summer, anyone looking for a full-coverage swimsuit should look no further. If cheekier styles aren’t your thing, this one-piece covers you from the neck down and features a complete brief. It includes a crew neckline and a front zipper that can be adjusted to display or conceal as much of your chest as you like.
- Pros: This suit was created primarily for aquatic activities including surfing, snorkeling, and paddle boarding. Because it’s compressive but not too tight, it’s also easy to layer over another swim top.
- Cons: Some reviewers wish it had greater chest support and a built-in bra.
Maaji Sapphire Long-Sleeve Reversible Swimsuit
Two bathing suits in one? We’ll accept it. This reversible piece gives the impression that you have extra suits in your closet. Wear the hibiscus side one day and pure black the next.
- Pros: Because this suit is reversible, it can be worn with or without the print.
- Cons: Because the back is chopped out, it does not provide complete sun protection.
Rash Guard Seea Palomar Crop Top
The textured rash guard from Free People is designed to protect your skin from sunburn while you’re out in the water. The lightweight fabric provides UPF 50 sun protection and may be layered over another bikini top; however, some reviewers notice that the top runs small.
- Pros: The textured fabric is popular among reviewers.
- Cons: Reviewers comment that the fabric does not dry quickly and that it is not ideal for surfing. Some of the colors are also off from the images.

J.Crew Active Long-Sleeve Rash Guard Swimsuit

- Pros: Sizes XXS to 3X are available. It’s also constructed of environmentally friendly materials like recycled nylon.
- Cons: Only A to B cup sizes are fully covered. To avoid fading, hand washing is advised.

Pros: Offers full coverage in the front and back and is fitting enough to be used under clothing.
Cons: For shorter torsos, size down; for longer torsos, size up.
Lululemon Waterside UVP Long-Sleeve Rash Guard

- Pros: It dries quickly, making it excellent for water sports and activities.
- Cons: When refilled, it tends to sell out quickly.

- Pros: This top is available in a variety of unusual patterns, like this Italian lemon tree and polka dots.
- Cons: It hits just below the ribcage, so it’s extremely cropped.
