O'Neill Men's Basic Skins UPF 50+ Short Sleeve Rash Guard - Sun Safe

Our review of the O'Neill Men's Basic Skins UPF 50+ Short Sleeve Rash Guard finds it best suited for active water users who want reliable sun protection without heavy bulk. The single biggest reason to buy is its UPF 50+ protection, which is recommended by the Skin Cancer Foundation and keeps sun exposure minimal during long sessions on the water. It wears like a close second skin thanks to a performance fit and a lightweight polyester/spandex blend, making it a practical choice for surfing, swimming, paddle sports, and casual beach days.

Key Features

• UPF 50+ protection: Blocks most UVA and UVB rays to reduce sunburn risk during extended outdoor sessions.
• Skin Cancer Foundation Recommended: Meets criteria for effective sun protection, offering peace of mind for frequent sun exposure.
• Performance fit: A form-fitting, tight layer that stays close to the body for reduced drag and easy layering under a wetsuit or life jacket.
• Minimal seam placement: Fewer seams reduce friction against the skin, which helps prevent chafing during paddling and surfing.
• Comfortable construction: A lightweight 6oz polyester/spandex fabric balances stretch and durability for a comfortable, long-lasting feel.
• Versatile use: Designed to perform across snorkeling, diving, paddle sports, and general swim use without feeling restrictive.

Who It's For

The Basic Skins rash guard is aimed at swimmers, surfers, and paddlers who prioritize sun protection and a low-profile fit. It works well for those who want a lightweight layer that can be worn alone in warm water or under a wetsuit on cooler days, and it is a good option for frequent beachgoers who value material quality and sun protection.

Those who prefer a boxier or loose-fitting shirt should look elsewhere, as the garment has a performance, skin-tight cut that some customers find very snug. If a relaxed fit or extra insulation is needed for colder conditions, choose a different style designed for thermal layering rather than this thin, close-fitting rash guard.

Pros & Cons
