Women Sunsuit One Piece Swimsuit UV Protection Chlorine Resistant: Top Picks for 2026

Overview

For women who swim laps in chlorinated pools and spend long hours in open water, the EcoStinger Women Sunsuit One Piece is a strong pick, because it pairs UPF50+ sun protection with chlorine-resistant fabric built to hold up through regular use. The shorty cut covers your core and upper legs, so you need less sunscreen on the areas that burn first.

The fabric blocks both UVA and UVB radiation. That is the main reason to choose a sunsuit over a standard swimsuit when your sessions stretch past an hour outdoors. The same snug coverage also shields your skin from jellyfish stings, sea lice and sandflies, which helps on ocean swims and snorkeling trips.

What you can expect from the fit and fabric

The suit runs slim and extra snug. If you prefer a standard fit, or you fall between two sizes, order one size up. The material is lightweight and stretchy with good recovery, so it moves with you through freestyle strokes, dives and beach volleyball without bunching.

Chlorine resistance means the suit tolerates frequent pool sessions with minimal care. You still get the longest life from it if you rinse it in cool fresh water after each swim and let it dry in the shade.

What other swimmers report

Customers rate the suit highly. Recent reviewers call it "super" and praise the clear product description and easy ordering process. One swimmer, writing in Spanish, says it performed excellently in water that was far from warm, which suggests the fabric offers some comfort in cooler conditions too.

A longtime buyer simply says she loves the product. The one mixed review focused on difficulty searching the website, not on the suit itself. If you have trouble finding your size or color, use the product category menus to go straight to the women's sunsuit line.
