Here is the size chart for selecting Arena swim trunks for men. These swim trunks are determined by your height, waist, and hip measurements to find your correct size.
If you happen to fall between two sizes, the most critical measurement is usually the hip measurement. Additionally, you should assess the desired fit. For a tight fit, choose the smaller of the two sizes. Conversely, opt for the larger of the two sizes if you prefer a looser fit.
