10 Best Plus-Size Men's Swim Trunks 2026 in the United States

These Big and Tall men's swim trunks are designed specifically for plus-size men, offering a relaxed fit with an elastic waistband and adjustable drawstring that helps ensure comfort and a secure fit. Made from 100% polyester, the fabric is lightweight, breathable, and quick-drying—usually drying within 5 to 10 minutes, which is great for beach or pool use. The trunks have a mesh lining inside, which adds comfort and support when wet. They include two side pockets, useful for carrying small items. The design features a vintage black American flag print created using vibrant dye-sublimation technology, providing a stylish look both in and out of the water.

Additionally, the trunks offer UPF 50+ sun protection, helping to block harmful UV rays—a valuable feature for outdoor water activities. On the downside, the swim trunks are only available in a single color and pattern, which might limit style preferences. Care instructions recommend cold hand or machine washing without bleach, which is typical but requires some care to maintain the vibrant print. This product suits those looking for reliable, comfortable, and sun-protective swimwear in a plus-size fit, but not those wanting multiple color options or more pocket security.
