What sets the Evo II Beach Boxer Side Zip Pockets apart

The Evo II Beach Boxer Side Zip Pockets is an all-in-one option for the pool, the sea and the beach. Stretch fabric and side vents give you room to move, the Lock Lace drawcord locks in your fit, and the anti-chafe inner brief adds comfort while you swim.

Key features

• Freedom of movement - Side vents at the hems and stretch fabric with 10% elastane make the trunks easier to move in
• Easy-to-adjust waist - The Lock Lace drawcord lets you fine-tune the fit at the waist
• Less chafing - The anti-chafe inner brief helps keep the trunks comfortable to wear
• Quick to dry - Lightweight fabric that's ready to wear again soon after your swim
• Clean finish - The zippered pockets, thermally welded hems and contrast taping give the trunks a clean, technical look
• Pockets for small items - Zippered side pockets, a zippered back pocket and a small mesh pocket inside the right side pocket keep small items secure when you're out of the water
• Rear drainage - Drainage holes at the back help water escape the trunks

Fabric and feel

The trunks are made from an innovative shell fabric - a pioneering swimwear material made from 90% recycled polyester and 10% elastane for 4-way stretch. The polyester content is fully recycled, helping reduce environmental impact.

Polyester is generally one of the most durable fabrics in swimwear and holds up well to regular use in chlorinated water. The elastane adds stretch and freedom of movement and helps the trunks follow the body, though it slightly lowers the fabric's chlorine resistance compared with swim trunks made from 100% polyester.

The fabric has a matte finish and is smooth to the touch, lightweight, quick to dry and hardwearing. That makes them a solid pick for your swim and the hours after, whether that's a walk along the beach or time in the sun.

Fit and sizing

The Evo II Beach Boxer Side Zip Pockets has a classic beach boxer cut with a slightly longer than mid-length leg that sits above the knee. It gives solid coverage without limiting movement.

Arena lists the length at 41.5 cm, which gives a useful reference for comparing different Arena cuts. The exact length can vary slightly by size.

Size guidance

These swim trunks fit true to size, and most men take their usual size. Still, always compare your measurements with the size chart before choosing a size.

In practice, many men can wear two adjacent sizes in trunks like these. The choice then comes down to how you want the trunks to sit across the thighs and at the waist.

A smaller size usually gives a closer fit across the thighs and a snugger waist. A larger size gives more room, especially across fuller thighs.

If your measurements fall between two sizes, it's usually best to choose the size your body measurements fall within most often.
