What are the best swimming shorts for men?
Men’s swim shorts come in three main styles: swim trunks, board shorts, and racing briefs. Each serves a different purpose, and the best one depends on how you plan to use them.
How to identify quality men’s swim shorts
- Look for polyester or polyester-spandex blends – they are durable and quick-drying (Boardcave Board Shorts Buying Guide).
- Polyester-and-spandex blends combine quick drying with flexibility (Boardcave).
- Lightweight synthetic fabrics are also fade-resistant to sun and chlorine (Men’s Health swim trunk guide).
Top brands for men’s swimwear in Ireland
Men’s Health’s 2026 swim trunk guide highlights brands like Speedo, Nike, and Adidas for their high-performance fabrics (Men’s Health). For board shorts, Billabong is a popular choice among Irish surfers. Dessue, a men’s swimwear specialist, notes that premium shorts often use hi-tech nylon for durability (Dessue buying guide).
Price vs. performance considerations
Performance-focused shorts with hi-tech woven polyester tend to cost more but last longer – a trade-off worth considering for regular swimmers (Dessue). Budget options around €15-€20 still work well for casual beach use as long as they are made from synthetic fabric.
The implication: your activity dictates the style, and polyester blends deliver the best versatility.
How to choose swimming shorts?
Follow these four steps to find the right pair for your needs, backed by expert advice from swimwear guides.
- Identify your primary activity – swimming laps, surfing, or lounging.
- Choose the right fabric – avoid cotton at all costs.
- Check the fit – snug but not tight, short enough for movement.
- Look for key features – liner, pockets, drawstring, quick-dry.
Consider your primary water activity
- For swimming laps: jammers or swim trunks with a shorter inseam (5-7 inches) reduce drag (Men’s Health).
- For surfing or beach days: board shorts (longer, looser) provide coverage and mobility (Boardcave).
- For children’s paddling: elastic-waist shorts with UV protection are ideal.
Check fabric and quick-dry properties
- Polyester dries faster than cotton – a key advantage in Ireland’s changeable climate (Boardcave).
- Spandex adds stretch for comfort and movement (Men’s Health).
- A four-way stretch fabric improves mobility for active beach use (Le Club Original beachwear guide).
Evaluate fit and length preferences
- Board shorts typically extend to the knee (Boardcave).
- Swim trunks usually have a 5- to 7-inch inseam for better water movement (Men’s Health).
- Racing briefs offer minimal coverage and maximum speed.
Look for added features (liner, pockets, drawstring)
- Most swim shorts include a built-in mesh liner for support (Men’s Health).
- Pockets with drainage mesh prevent water pooling (Boardcave).
- A drawstring helps secure the waist, especially in stretchy shorts.
Choosing between board shorts and swim trunks comes down to activity: board shorts are built for surfing and beach lounging, while trunks offer better performance for actual swimming. Ireland’s cool water means quick-dry fabric isn’t just a luxury – it’s a practical must.
The pattern: short trunks for speed, long boards for versatility, and always synthetic fabric.
What materials are used in swimming shorts?
Three fabric categories dominate the market, each with distinct trade-offs.
Polyester blends
- Polyester is the most common material for swim shorts because it is durable, quick-drying, and holds colour well (Boardcave).
- Blending with spandex adds stretch and a more tailored fit (Men’s Health).
- Hi-tech woven polyester is considered the best material for men’s swim shorts in terms of durability and shape retention (Dessue).
Nylon and spandex mixes
- Nylon is used in premium shorts, offering a soft feel and good flexibility (Dessue).
- Nylon-spandex blends are lightweight and dry almost as fast as polyester.
Eco-friendly options
- Many board shorts are now made from recycled polyester, reducing plastic waste (Boardcave).
- Merino wool is reportedly soft, breathable, and relatively quick-drying, though less common (Mommypotamus natural swimwear guide).
Polyester and nylon both dry quickly, but polyester is more fade-resistant, while nylon feels softer against the skin. Eco-friendly options are expanding, but they may cost 20-30% more – a premium worth paying if you swim frequently.
What this means: the material you choose should match your tolerance for cost and your sensitivity to feel.
Where to buy swimming shorts in Ireland?
Ireland’s changeable weather makes quick-dry fabrics essential, as noted by Met Éireann’s climate data (Met Éireann – Ireland’s national meteorological service). When shopping, look for shorts made from polyester or nylon – avoid cotton entirely.
Key factors for Irish buyers
- Quick-dry performance is critical: polyester dries much faster than cotton (Boardcave).
- Chlorine resistance matters for pool use – seek fabrics labelled ‘chlorine-resistant’ (Men’s Health).
- UV protection (UPF 50+) is a bonus for sunny beach days.

How to care for swimming shorts?
Proper care extends the life of your swim shorts significantly. Most synthetic shorts last 6–12 months with regular use, but following a few simple steps can double that.
Rinse after each use
- Rinse in cold water after swimming in chlorine or salt water to remove harsh chemicals (Boardcave).
- This prevents elastic fibres from degrading prematurely.
Machine wash cold with mild detergent
- Wash in cold water with a gentle detergent – hot water breaks down spandex (Men’s Health).
- Avoid fabric softeners as they coat the fabric and reduce quick-dry effectiveness.
Air dry – never tumble dry
- High heat shrinks synthetic fabrics and degrades elastic fibres (Men’s Health).
- Hang in shade; direct sunlight can fade colours over time.
Confirmed facts
- Swim shorts are made from synthetic materials that dry quickly (Boardcave).
- Most swim shorts have a built-in mesh liner (Men’s Health).
What’s unclear
- Which brand offers the best durability for regular pool use.
- Whether board shorts are appropriate for serious swimming.
- If board shorts with drainage pockets truly reduce drag.
- Top retailers in Ireland include Elverys, Lifestyle Sports, and Sports Direct (based on market presence).
The catch: even the best shorts need proper rinsing and air drying to last more than one season.

Frequently asked questions
Can I wear swimming shorts for running or gym workouts?
Swim shorts lack the support and moisture-wicking properties of athletic shorts, so they are not ideal for running or gym sessions. They are designed for water activities only.
How often should I replace my swim shorts?
With regular pool use, expect to replace them every 6–12 months when the elastic waistband or liner loses its shape. Signs include sagging, fraying seams, or reduced stretch.
Are swim shorts with pockets good for swimming?
Yes, as long as the pockets have drainage mesh to prevent water from weighing them down. Most board shorts now include this feature (Boardcave).
What is the difference between men’s and women’s swim shorts?
Men’s swim shorts generally have a longer inseam, a looser fit, and a mesh liner. Women’s swim shorts are cut with a higher waist and shorter leg, often made from the same quick-dry fabrics.
Do swim shorts shrink after washing?
Polyester and nylon blends shrink minimally if washed cold and air dried. High heat from a tumble dryer can cause significant shrinkage (Men’s Health).
Can I wear swim shorts in a hot tub or jacuzzi?
Yes, but the combination of heat and chemicals (chlorine) degrades elastic faster. Rinse immediately after use to prolong the life of the shorts.
Are there swim shorts with UV protection?
Yes. Many board shorts and swim trunks now offer UPF 50+ fabric, which blocks 98% of UV rays. Check the product label for the UPF rating.
How to remove chlorine smell from swim shorts?
Soak them in a mixture of cold water and a small amount of white vinegar for 15 minutes, then wash with mild detergent. Avoid bleach as it damages synthetic fibres.
For anyone swimming off the Irish coast, the choice is clear: invest in quick-dry polyester shorts with a mesh liner and drainage pockets, or spend summer peeling wet cotton off your skin.
