10 Best Swim Shirts For Men 2026 in the United States

The Roadbox Men's UPF 50+ Long Sleeve Shirt is designed for outdoor activities including swimming, fishing, hiking, and more. Made from ultra-soft polyester with a UPF 50+ rating, it offers strong protection against harmful UVA and UVB rays, helping keep your skin safe during extended sun exposure. The fabric is lightweight, breathable, and quick-drying, which means it wicks away moisture to keep you comfortable and cool even when you're active or sweating.

Its loose fit and raglan sleeves allow for good freedom of movement, while flat-lock seams and a tag-free collar reduce irritation, making it comfortable to wear for long periods. The long sleeves provide full arm coverage for sun protection. This shirt is a solid choice for men looking for reliable sun protection and comfort during a wide range of outdoor activities, especially if you want a breathable, easy-care option that doesn’t restrict movement.

Note that the shirt’s loose fit may not feel as snug as some prefer in swim gear, particularly for water sports requiring a more form-fitting option. Also, while the polyester fabric dries quickly, it may not be as soft as some higher-end materials.

The O'NEILL Men's Basic Skins 50+ Long Sleeve Rash Guard is a solid choice for sun protection during water activities. Made from a stretchy blend of polyester and spandex, it feels like a second skin, offering a snug, performance fit that’s great for surfing, swimming, or paddle sports. Its UPF 50+ rating means it blocks out most harmful UV rays, which is why it’s recommended by the Skin Cancer Foundation.

The long sleeves provide extra coverage, and the minimal seam design helps reduce irritation and chafing, enhancing comfort when you're active. The fabric is designed to be quick-drying and moisture-wicking, so you won’t feel weighed down by water or sweat.

This rash guard features a tight and form-fitting style, so it’s best suited for those comfortable wearing something close to the body. It is a durable, well-made rash guard that balances sun protection and comfort, ideal for men who spend a lot of time in the water and want reliable sun defense without bulk.
