O'Neill UV Sun Protection Women's Basic Skins Rashguard - UPF 50 Beach

In this review of the O'Neill Basic Skins long-sleeve rashguard, the bottom line is simple: it is a purpose-built swim top for anyone who spends long days on the water and needs reliable sun and rash protection. The shirt's single biggest selling point is the combination of UPF 50+ ultraviolet protection and a performance, form-fitting cut that feels like a second skin. Built from polyester and four-way stretch spandex with flatloc seams, this top balances comfort and durability for surfing, paddle sports, or casual beach use.

Key Features

• UPF 50+ protection: Blocks the majority of harmful UV rays so users can stay in the sun longer with less risk of sunburn.
• Skin Cancer Foundation recommended: Gives added confidence that the product meets recognized sun-protection standards.
• Comfortable polyester/spandex blend: The 6oz construction and four-way stretch allow freedom of movement for paddling or swimming while maintaining shape.
• Minimal seam placement: Reduces chafing and provides targeted rash protection in areas that most commonly rub during activity.
• Performance fit: A form-fitting, tight layer that sits close to the body to prevent bunching under wetsuits or during high-movement sports.

Who It's For

The Basic Skins long-sleeve is ideal for women who surf, swim, kayak, or spend extended time boating and need dependable sun protection and a low-profile layer. It works well as an outer layer on sunny days and as a base layer under a wetsuit when cooler water requires insulation.

Those who prefer a loose, relaxed rashguard or need more forgiving sizing may want to try a relaxed-fit top instead, since some users find this model quite snug and recommend sizing up when in doubt.
