Design & Fit

The Arena Isa is a refined shaping swimsuit with a clean, timeless look. The front features a soft, squared neckline and smooth shaping lines that help create a streamlined appearance through the torso. The Squared Back and adjustable straps work together to keep the swimsuit securely in place while following the body’s natural movement. The medium-cut leg offers comfortable coverage around the hips without feeling restrictive, while the inner bra provides gentle shaping and dependable bust support. The Isa is a great choice for women who want a shaping swimsuit that feels simple, elegant and comfortable for everyday swimming.

Shaping & Support

As part of the Arena Shapewear line, the Isa is designed to shape the body in a natural, comfortable way. The integrated Power Mesh tummy control panel supports the midsection and helps smooth the silhouette without digging in. At the same time, Sensitive® FIT fabric offers light, even shaping across the whole suit, enhancing your natural lines instead of hiding them. The result is a swimsuit that boosts your confidence whether you are swimming laps, doing aquafitness, relaxing at the spa or unwinding in the Icelandic hot tubs.

Comfort & Fabric Technology

The Isa combines Sensitive® FIT fabric with Lycra Xtra Life™ to deliver a strong blend of shaping, support and comfort. The fabric feels soft against the skin, offers reliable stretch and is engineered to withstand frequent exposure to chlorinated water, sunscreen, sweat and oils. It is quick-drying and breathable, and it also provides UPF 50+ UV protection, making it suitable for both indoor pools and outdoor swimming. Designed for regular use in chlorinated pools, the Isa helps maintain its fit and color over time, even with frequent swimming in Icelandic swimming pools.

Sizing

• True to size – most women choose their regular size
• We recommend the swimsuit fits snugly when tried on dry, without causing discomfort
• Fabric expands slightly in water – the shaping swim fabric expands slightly in water, so a comfortably snug fit when dry helps the suit support and smooth without feeling too tight in the pool.

Who is the Arena Isa swimsuit for?

The Arena Isa is ideal for women who want a shaping one-piece swimsuit that combines support, a clean, understated look and lasting comfort. It is especially suitable for regular pool swimming, aquafitness, spa visits, wellness routines and relaxing in hot tubs. The shaping features adapt to a wide range of body types, helping to smooth the silhouette – especially around the tummy and torso – while still allowing natural movement and everyday wearability.
