What makes the Arena Solid Beach Boxer stand out

The standout feature is a very thin, lightweight nylon fabric that does not absorb water the way heavier swim shorts do. The fabric dries quickly, which keeps the trunks comfortable when you step out of the water and carry on with your day. The pocket setup is built for relaxed, off-the-water use too: open side pockets on both sides and a back pocket with hook-and-loop closure for small items. Two eyelets at the back and an eyelet on the back pocket help water drain faster after swimming. Blue drawstring tips and blue eyelet rings add a clean accent to the black trunks without taking away from the classic look.

Fabric & feel

Arena Solid Beach Boxer trunks are made from 100% recycled polyamide — a very thin, lightweight and quick-drying fabric. The material has a smooth, light feel and is built to wick moisture away from the body without absorbing water. That means swim trunks that feel less heavy after swimming and work well when you want to get out of the water and continue your day without staying cold or wet for long.

Polyamide is a strong, quick-drying fabric. It is not as well suited to very frequent chlorinated pool use as polyester, so we recommend rinsing the trunks in clean, non-chlorinated water immediately after pool use to help extend the life of the fabric.

Fit & sizing

Solid Beach Boxer is a classic boxer-style swim trunk with a length that is slightly longer than mid-length, so the trunks sit above the knee. The fit is loose and comfortable, with good coverage that does not restrict movement.

Arena lists the length as 41.5 cm, but length varies slightly by size. The listed length is therefore best used to compare different Arena cuts.

Size guidance

These swim trunks fit true to size, and most men choose their usual size. Still, start by comparing your measurements with the size guide before ordering.

In practice, many men can fit into two adjacent sizes in this type of swim trunk. In that case, the choice often comes down to how you want the trunks to sit through the thigh and at the waist.

The smaller size usually gives a closer fit through the thigh and a snugger waist. The larger size gives more room, especially if you have fuller thighs.

If your measurements fall into two sizes, it's usually best to choose the size that matches most of your body measurements.

Best for

• The beach and the poolside
• Sea swims and use in the sea
• Hot tubs, lagoons, natural pools and spa visits
• Pool sessions when the trunks are not used very frequently in chlorinated water
• Travel at home and abroad

Less ideal for

Arena Solid Beach Boxer are not the first choice for daily or very frequent use in chlorinated water. If you swim often in chlorinated pools or want maximum durability for that type of use, polyester swim trunks or swim shorts, briefs or jammers are usually a better choice.
