Recommended series: sports and fitness series, competitive series
 
The international first-line brand that can stand shoulder to shoulder with Speed in the swimming product market should be Arena, which was born in France in 1973. It is an official partner of FINA and has sponsored many international competitions and national swimming teams, and many of the top swimmers have worn Arena swimsuits to compete, winning medals and even breaking records in various events. For example, at the London Olympics, Japanese breaststroke star Kosuke Kitajima won the silver medal in the 4*100 mixed relay in a Arena swimsuit, and the American female breaststroker Rebecca Soni won two golds and one silver.
 
Arena professional swimwear is mainly divided into two categories: Racing series and Fitness series.
 
The PowerSkin Competitive Swimsuit on the official website is divided into two categories: carbon fiber and carbon fiber, the main PowerSkin Carbon series is made to make the swimsuit have better stretch due to the addition of light weight and high strength carbon fiber, while nylon and elastic fiber make the swimsuit improve softness and color retention while effectively resisting chlorine. This series of swimsuits are all one-piece knee-length models with solid color blocks, but they are not easy to buy in China, and you need to buy them on foreign official websites or buy them overseas.
 
The competitive series of swimsuits sold in China are made of Arena's own developed X-PYTHON-P fabric, which is a blend of polyester and spandex, and the spandex content of some swimsuits can reach 34%. With a horizontally oriented fabric method, the density is higher and the swimsuit is thinner.
 
Most of the swimwear in the fitness series is made of 80% polyester and 20% spandex blended AQUA PRO EX fabric, and there are also 100% polyester components. This fabric is a 40-needle fabric, which is tighter than ordinary 32-needle fabric, softer to the touch, and excellent color fastness makes the color of the swimsuit last for a long time. However, AQUA PRO EX fabric does not add special anti-chlorine technology, and is inferior to similar products of Subtao in terms of chlorine resistance.
 
Arena swimsuits are sewn with a four-needle and six-thread stitching process, which is a high-level sewing process in sportswear production, with meticulous stitching and tight stitching. Therefore, compared to most swimsuits made with three-needle and five-thread technology, Arena's swimsuit products are stronger and more durable, and are less prone to the embarrassing situation of sewing thread bursting during swimming.
 
Born in France, the fashion capital of the world, Arena not only focuses on the research and development of high-tech swimsuit fabrics in terms of performance, but also maintains new fashion in style and color without publicity. Compared to the Speedo, which is dominated by cool colors, the Arena Fitness swimsuits come in a variety of colors, supplemented by colorful lines or prints, and the style design is better. Women's fitness swimsuit is an X-shaped open back design without steel bracket insert chest pad, which is convenient for training, and the price is mostly about 300-400 yuan.
 
The women's competitive swimsuit is an X-shaped open back design without underwire pads, which meets the requirements of flexible shoulder and back movement of swimming fitness, and can reduce the water resistance caused by swimming competitions, with prices ranging from 350 to 800 yuan.
 
The two series of men's swimsuits are mostly knee-length, with fashion prints, and the price of the competitive model is on the expensive side, with a price of between 200-700 yuan, while the sports and fitness model is mostly about 200 yuan.
