Choosing men’s swim shorts: pay attention to material, fit and intended use

Choosing a new pair of swim shorts may seem straightforward, but small differences can affect how much you enjoy wearing them. A pair that feels comfortable on the beach may be too loose for swimming lengths. Lightweight fabric often dries faster, but it also needs careful washing. And an adjustable drawcord only helps when the waistband fits properly.

As a Joybuy Product Recommendation Officer, I filter product information for practical details. This helps you avoid choosing based solely on colour, brand name or a striking marketing claim.

Common pitfalls when choosing men’s swim shorts

1. “Quick-drying” without clear material specifications

The term quick-drying swim shorts does not tell you much on its own. Check whether the product information states the material. Polyester swim shorts can feel lightweight, and according to the product descriptions of various models, they are designed to help you move more easily from the water to dry land after swimming. That does not mean every polyester fabric dries at the same speed or feels the same.

Pay attention to the lining, too. An outer fabric made from 100% polyester with a polyester lining may feel different from a pair without an inner layer. This information is relevant for pool training, holidays and beach use.

2. A waistband that does not suit your activity

A fully elasticated waistband can be comfortable, but when swimming actively you also want sufficient support. Swim shorts with a drawcord give you extra adjustability. Check whether the cord is internal and whether the waistband fits securely without feeling tight.

For relaxing in the sun or walking, a looser fit is usually not a problem. When diving, swimming or taking part in water sports, overly loose shorts may shift out of place. So do not just look at the letter size; check the size guide and the description of the fastening as well.

3. Buying one pair of shorts for every occasion

Sporty men’s swimwear is not automatically suitable as everyday clothing. Swim shorts are designed for water and leisure, while men’s boxer shorts, men’s cotton trunks and men’s stretch underwear are intended for everyday wear under clothing.

Cotton can feel comfortable and breathable, while polyester may be more practical for swimming and outdoor activities. Decide how you plan to use the item first, then choose the style.

Which features are important?

Material: polyester, cotton or a blend

For swim shorts for the pool and beach, these points are useful to consider:

  • 100% polyester: The Reebok models in this selection use 100% polyester for both the outer fabric and lining. According to the product information, the fabric is lightweight, breathable and designed for swimming and leisure use.
  • Cotton blend with elastane: According to the product information, the Lee Innes trunks are made from 57% cotton, 38% polyester and 5% elastane. These are underwear, not swim shorts, but the stretch can feel comfortable during everyday movement.
  • Elastane: A small amount of elastane can provide flexibility. It does not guarantee a particular fit; the cut and size remain decisive.

Brands may mention features such as durability or colour retention when exposed to chlorine, salt water and UV rays. According to Reebok's product information, the polyester construction is intended for this purpose. Actual lifespan also depends on how the item is used, rinsed and washed.

Fit and size

Ideally, measure your waist where you wear your swim shorts. Compare the result with the product’s size guide. A size from S to XL may fit differently depending on the model.

Pay attention to:

  1. Waistband: Elasticated for freedom of movement, with a drawcord for extra adjustment.
  2. Length: A shorter style gives you greater freedom of movement, while a longer style provides more coverage.
  3. Lining: Check whether there is an inner lining and what it is made from.
  4. Room for movement: The shorts should not pull tight when walking, sitting or swimming.

Blue swim shorts are easy to pair with a T-shirt or flip-flops. Colour is a style choice, however, and says nothing about drying time, fit or material.

Care and expected lifespan

Always follow the care label. According to the product information, the Reebok swim shorts in this selection are machine washable at 30 °C. Bleaching, ironing, tumble-drying and dry cleaning are not recommended. The Lee trunks are machine washable; follow the label for precise drying and ironing instructions.

Rinse your swim shorts with clean water after using them in the sea or a swimming pool. Leave them to air-dry and avoid unnecessary heat. This helps reduce stress on the fibres and elastic. Care instructions cannot guarantee a fixed lifespan, but they can help keep the fit and material usable for longer.

Frequently asked questions about men’s swim shorts

How do I know which size swim shorts I need?

Measure your waist and compare the result with the size guide for the specific model. Also consider the cut, waistband and whether there is a drawcord. Sizes S to XL are not fully standardised; the same letter may fit differently depending on the brand or model.

Is polyester suitable for swimming in a pool and the sea?

Polyester is often used in swimwear because it is lightweight and easy to care for. According to the product information for the Reebok models mentioned, they are intended for use in the pool, salt water and on the beach. Rinse the shorts after use and follow the care label to look after the material properly.

How long do swim shorts last?

This depends on how often you swim, exposure to chlorine or salt water, sunlight and how the shorts are washed. There is no fixed lifespan for all swim shorts. An adjustable waistband, clearly stated material composition and careful maintenance can help you get longer use from your purchase.
