For regular pool swimming
This Arena one-piece is made with a chlorine-resistant weave and a lining, making it suited to time spent in chlorinated pools, whether for laps, lessons, or casual swims. The fabric is a smooth, lightly lustrous knit typical of swimwear.[2,3]
Swimming in a simple, adjustable one-piece
This one-piece is suited to swimming sessions where a simple, comfortable fit matters. The adjustable straps let you fine-tune the fit at the shoulders, while soft, unpadded cups are intended to provide natural shaping. The design includes a low V-back and thin straps with slider hardware.[2,3]
Product comparison
Compared within this brand.
| Swim One-Piece: Choose this if you want a lined, chlorine-resistant one-piece for regular pool swimming, with a scoop neckline, bikini-cut leg line, and a low V-back. It suits swimmers who prefer soft, unpadded cups for natural shaping and adjustable straps, and it comes in Slate Grey in sizes 34 to 40. Plan on gentle care: the manufacturer recommends rinsing immediately after use in non-chlorinated water, washing with delicate detergent, and air-drying away from heat.[1,2,3,4] | Logo Swim One-Piece: Choose this if you want a chlorine-resistant, fully polyester-lined one-piece for regular pool swimming, with soft unpadded cups for natural shaping and a racerback with a large rounded lower-back cutout. Its bikini-style, high-cut leg design and smooth form-fitting fabric suit swimmers who prefer a sleek, second-skin feel — the brand describes the fit as reducing water drag for better glide. Note that one Reddit swimmer reported an Arena suit was very comfortable but started disintegrating fairly fast, and Arena sizing tends to run a bit tight compared with some brands, so some swimmers size accordingly; it comes in black in sizes 30 to 34.[5,6,7,8,9,10] |
