Description
xThe body is made from 100% recycled nylon, keeping the short light and comfortable in and out of the water. The sustainable fabrication doesn’t compromise on durability or feel. A responsible choice that holds up session after session.
An elasticated waistband with an external drawcord lets you dial in the fit before you get in the water. The 16“ side length sits just above the knee for a classic, easy-wearing silhouette. Whether you’re doing laps or poolside drills, the fit stays put.
A built-in mesh basket liner made from 100% recycled polyester adds support and eliminates the need for separate trunks underneath. Side pocket drainage channels water away quickly so the short doesn’t feel heavy. Practical details that make a real difference during active use.

Allens Swimwear is a family-run business founded in 1976 by Dennis Allen and his daughter Linda Beal. It started from a genuine need. “With 2 swimmers in the family it was often difficult to find the right kit, so dad and I took the plunge and started selling to local swimmers at our local pool in Kingsbury out of a suitcase and we’ve never looked back.” Today, Linda, her husband Richard, and three of their children Danny, Will and Jenna still run the business together. The suitcase may be long gone, but the founding principle of helping swimmers get the right kit remains exactly the same.

Size chart
This size guide covers Speedo Global Fit adult men's swimming shorts in extended alpha sizes XXS–5XL. All measurements are body measurements taken from your own body, not garment measurements. Always use both your hip and waist measurements as the primary guide — if they suggest different sizes, use the hip measurement to decide. These sizes apply to all countries.

Take all measurements directly against your skin using a soft tape measure. All measurements are body measurements, not garment measurements.
*Hip measured around the fullest part of the seat, tape parallel to the floor. **Waist measured at the natural waistline. If hip and waist suggest different sizes, use the hip measurement to decide.

*Hip measured around the fullest part of the seat, tape parallel to the floor. **Waist measured at the natural waistline. All measurements are body measurements, not garment measurements. If hip and waist measurements suggest different sizes, use the hip measurement to decide.
Measure your hip and waist against your skin with a soft tape measure. Use both measurements to identify your size in the table above. If they fall in different size columns, use the hip measurement to decide. All measurements refer to your body, not the garment.
If your measurements fall between two sizes, size up. Most Speedo men's styles include an internal drawcord which allows the waistband to be taken in slightly, so a marginally larger size can still be adjusted for a secure fit at the waist. Speak to a member of staff at Allens if you are unsure.
Speedo's extended alpha sizes (XXS–5XL) are designed for products which fall outside the standard numeric range (26–46). The sizing is based on the same body measurement system — always use your hip and waist measurements to find the correct size, regardless of which size range you are shopping from.
Yes. The extended alpha sizes (XXS–5XL) use a single global measurement system that applies across all countries. There are no regional size equivalents for this range — simply measure your hip and waist and compare directly to the body measurement table above.
The extended size range covers Speedo's recreational and fitness swimwear. For competitive pool swimming, Speedo's Fastskin racing range is specifically designed and World Aquatics approved, though availability in extended sizes may vary. Speak to a member of staff at Allens for guidance on the right product for your level and size requirements.
Speedo swimwear is primarily designed for pool use. While the chlorine-resistant fabrics will withstand occasional use in open water or the sea, prolonged exposure to salt water can accelerate fabric wear. Rinse thoroughly in fresh water after every use, whether in a pool, the sea, or open water.
Rinse in cold fresh water immediately after every use to remove chlorine, salt, and sunscreen. Hand wash gently with a mild detergent if needed. Do not machine wash, tumble dry, iron, or dry-clean. Store flat and dry, away from direct sunlight. Avoid sitting on rough pool surrounds as this can cause premature fabric wear.
