Choosing men's swim shorts: a practical buying guide for the beach, pool and sport

A good pair of swim shorts needs to do more than just look sporty. In the UK, you might wear them at the beach, in the pool, on holiday or for a quick dip after exercising. However, there are several common pitfalls that can make a purchase less practical than expected.

Common pitfalls when choosing men's swim shorts

1. Mistaking sports shorts for swim shorts
Not every pair of shorts is suitable for the water. Cotton men's sports shorts can feel comfortable in your free time, but they often stay damp for longer and may feel heavier after swimming. Always check the fabric composition and whether the product description specifically mentions swimming.

2. “Quick-drying” without clear fabric specifications
A marketing claim means little if the material used is not stated. Polyester is often used for quick-drying men's swim shorts, but drying time also depends on the construction, lining and amount of fabric. Look for a specific composition, such as 100% polyester, and read the care instructions.

3. A waistband that does not stay in place
An elasticated waistband without an additional adjustment option can shift while swimming, diving or exercising. Swim shorts with a drawstring give you more control over the fit. Also pay attention to the size chart: sizes M to XXL can fit differently from one brand to another.

The key specifications to check

1. Material and drying performance

For swimming and beach use, lightweight polyester is a practical choice. The product descriptions for the Reebok swim shorts below state 100% polyester for both the outer fabric and lining. According to the product descriptions, these models are designed to feel less heavy after contact with water, so you can continue wearing them comfortably.

For training or everyday use, a cotton blend may feel more comfortable. According to the product description, the Under Armour Rival Terry 6In Short consists of 80% cotton and 20% polyester. This makes it more suitable as a sporty leisure short than as a traditional swim short. According to the brand description, the fabric is designed to wick away moisture and dry quickly, but always check the care information and intended use.

2. Waist and freedom of movement

A combination of an elasticated waistband and drawstring is useful when wearing shorts for swimming, walking or sport. A regular fit generally offers more room for movement than a close-fitting style. Also check the inside leg length. According to the size chart, the Under Armour shorts have an inside leg length of 15 cm in the stated sizes M to XXL.

Pay attention to the waist, hip and length measurements rather than relying only on the letter size. Measure your natural waist and compare it with the product page. If you are between two sizes or want a looser fit, the product information for some models suggests considering the larger size.

3. Care and durability

Salt water, chlorine and sunlight can put strain on fabric. According to the product descriptions, the Reebok models are designed for regular contact with salt water, chlorine and UV radiation. This is a claim made in the brand's product information and is not a guarantee of a specific lifespan.

Care does make a difference. According to the stated instructions, the Reebok swim shorts can be washed at 30 °C, but must not be tumble-dried, ironed or dry-cleaned. Always follow the label on the product you receive. This helps reduce the risk of distortion or colour loss.

How to choose the right size

We recommend following this order:

  1. Measure your waist where the shorts usually sit.
  2. Check the hip measurement and inside leg length in the product table.
  3. Compare the size chart with a pair of shorts that fits you comfortably.
  4. Choose a regular fit for everyday use or a roomier style for the beach and leisure time.
  5. Check whether the drawstring is internal or external and whether pockets are important to you.

A size label such as XL is not universal. For example, the waist measurements listed in the Under Armour size chart range from M to XXL. Always check the measurements in centimetres before ordering.

Frequently asked questions about men's swim shorts

Which men's swim shorts dry quickly?

Lightweight polyester styles are often chosen because they absorb little moisture. According to the product information, the Reebok Yale and Yestin models are made from 100% polyester. The “quick-drying” description comes from the product listing; actual drying time depends on the wind, temperature, lining and amount of water retained by the fabric.

Can I use sports shorts for swimming?

Sometimes, but not every pair of sports shorts is designed for this purpose. According to the product description, a cotton-rich style such as the Under Armour Rival Terry is primarily intended for training, leisure time and everyday use. For regular swimming, a style that explicitly mentions swimming, polyester and a suitable lining is generally the more sensible choice.

How long do swim shorts last?

It is not possible to determine a fixed lifespan in advance. Frequent contact with chlorine, salt water, sunlight and sun cream can put strain on the fabric. Wash the shorts according to the label, avoid tumble-drying when advised against and rinse out chlorine or salt water after use. The quality of the material, seams and waistband, together with proper care, determines how long the shorts remain usable.
