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 Willit Men's Rashguard Swim Shirt is a solid choice for men needing reliable sun protection and comfort in water-related or outdoor activities. Its fabric is 100% polyester with quick-dry and moisture-wicking properties, helping you stay comfortable by pulling sweat away from your skin and drying fast after swimming or sweating. The UPF 50+ rating is excellent, offering strong defense against UVA and UVB rays, which is essential for extended time in the sun.

The flatlock seams and tagless collar reduce chafing, enhancing comfort during active use. Raglan sleeves and four-way stretch fabric provide good flexibility and freedom of movement, useful for swimming, running, fishing, or hiking. One possible downside is that the shirt is described as fitted but not too tight, so if you prefer a looser fit, this might feel a bit snug. Also, being 100% polyester, it may not feel as soft as natural fabrics for some users.

Machine washable care is a practical plus for easy maintenance. This swim shirt is best suited for men who want dependable sun protection combined with lightweight, flexible fabric for various outdoor activities.

Its slim fit hugs the body, especially around the shoulders and waist, which helps reduce drag in the water but might feel tight if you prefer a looser shirt. The short sleeves and raglan seam design provide good freedom of movement while swimming, and flat seaming helps prevent skin irritation.

This swim tee is best for men looking for a performance-oriented, sun-protective shirt with a sleek fit, suitable for both swimming and outdoor use. For those who prefer a roomier or longer sleeve style, exploring other options might be beneficial.
