O'Neill Wetsuits Women's Basic 50+ Long Sleeve Rash Guard - UPF 50

Our review of the O'Neill Wetsuits Women's Basic 50+ Long Sleeve Rash Guard finds it best for active beachgoers who want sun protection and a streamlined fit without a heavy wetsuit. The bottom line: this is a lightweight, performance-oriented rash guard with UPF 50+ protection and a snug, second-skin fit that keeps chafing and UV exposure to a minimum during surfing, paddling, or pool laps. It balances value and function, delivering O'Neill quality in a simple, comfortable pullover designed for frequent aquatic use.

Key Features

• UPF 50+ Ultraviolet Protection: Provides high-level sun defense so long sessions on the water reduce UV exposure to skin.
• 6oz Polyester/Spandex Construction: The fabric blend is comfortable and durable, offering stretch for paddling and movement without losing shape.
• Minimal Seam Placement: Strategically placed seams limit chafing and increase overall rash protection during long rides or repetitive strokes.
• Performance Fit: A form-fitting, tight layer fits like a second skin for streamlined movement and under-wetsuit layering.
• Easy Care: Machine washable and pull-on closure make it low maintenance for regular water-sport use.

Who It's For

This rash guard is ideal for women who surf, swim laps, stand-up paddle, or spend extended time boating and want reliable sun protection with a sporty fit. The snug, performance-oriented cut suits active users who prefer a tight layer that moves with the body and reduces drag in the water.

Those who want thermal insulation for cold-water diving or a loose, casual beach shirt for all-day lounging should look elsewhere, since this piece is intended as a lightweight protective layer rather than a thermal wetsuit or relaxed-fit top.
