What sets the Evo II Beach Boxer Solid apart

The Arena Evo II Beach Boxer Solid isn't just a plain, simple swim trunk — it pairs a clean, classic solid look with the technical construction of Arena's Evolution beachwear line: 4-way stretch fabric, an anti-chafe inner mesh brief, a Lock Lace drawcord, thermally welded hems and split lower side hems for better movement.

That makes this style different from a basic solid swim trunk. It's built for men who want a more technical swim short with practical storage, secure waist adjustment and better comfort during active use. The zippered back pocket, open side pockets and small inner mesh pocket inside the right side pocket also make these trunks more useful out of the water than many standard swim trunks.

Fabric & feel

Arena Evo II Beach Boxer Solid swim trunks are made from a strong, lightweight and quick-drying swim fabric — 90% recycled polyester and 10% elastane, with 4-way stretch. The fabric has a smooth, comfortable hand and dries quickly between uses.

Polyester is widely used in swimwear because it is durable, quick-drying and well suited to repeated use in chlorinated water. The elastane makes the fabric more flexible and helps the trunks move better with the body.

The mesh inner brief has anti-chafe taping along the seams to help reduce rubbing during longer wear — useful when the trunks are worn for long stretches in the pool, hot springs, geothermal lagoons, hot tubs, sea swims or while travelling.

Fit & sizing

A classic boxer cut in a mid-length that sits above the knee. Reliable coverage without restricting movement. The split lower side hems and 4-way stretch fabric make the trunks especially comfortable when you need more freedom of movement, whether you're swimming, travelling or spending time by the water.

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.

Built for

• Regular pool visits and hot tubs
• Hot springs and geothermal lagoons
• Sea swims and use in the sea
• Spa visits
• Beach days and light activity by the water
• Travel — at home and abroad

Less suited for

For competitive swimming or regular lap training, swim shorts, briefs or jammers are usually a better choice.
