The O'Neill Wetsuits men's Basic Skins 50+ L/S Rash Guards stand out in the swim shirts for men category, particularly for those who spend a lot of time in the water. With a UPF 50+ rating, this rash guard offers excellent protection against harmful UV rays, making it a solid choice for beach days, surfing, and other outdoor water activities. The Skin Cancer Foundation recommends this product, emphasizing its protective qualities.

This can be particularly appealing to active users who enjoy vigorous water sports.

There are a few considerations to keep in mind. The rash guard is designed for a tight fit, which may not appeal to everyone, especially those who prefer a looser style for casual wear. Additionally, the care instructions recommend hand washing only, which could be a hassle for some users looking for low-maintenance options. Lastly, while it’s a great choice for sun protection and comfort, it may not provide insulation in colder waters, so users should pair it with other gear if water temperatures drop.

The UPF 50 rating provides strong sun protection, making it suitable for long hours outdoors.

Its slim fit design hugs the body closely, which can be great if you want less fabric flapping in the water, but might feel tight for those who prefer a looser fit. The short sleeves and raglan seams give good arm mobility, and the exposed flat seams help reduce irritation, which is a nice touch for sensitive skin.

This swim shirt is a practical, lightweight option that balances sun protection and comfort well, especially for casual swimmers or those spending time in the sun.
