Baltic Top
£39.99
The Baltic swim top is built for comfort without compromise. Designed for wild swimmers in search of greater support, it holds you comfortably and securely in place regardless of bust size, so you can focus on the water - not what you're wearing. No padding. No underwire. Just clever construction with princess seams, a wide underband, and full power mesh lining that offers natural support where you need it most.
Pair it with the Baltic briefs or mix it with the Nefyn bottoms to find the fit that works for you.
Why you'll reach for the Baltic top
-
Built-in volume and support - Power mesh lining, princess seams and a wide underband
-
Zip and swim - Easy-on front zip with a locking slider to stay secure
-
Made to move - Shoulder strap design gives freedom to swim naturally

Swimwear that lasts - High-quality fabric that resists UV, chlorine and sun cream
Find freedom in the water
Whether you're dipping into a mountain tarn or clocking up distance along the coast, the Baltic top is designed to help you feel confident in the water. The snug fit and clean cut make it a natural choice for wild swims, while the front zip makes it easy to get on and off at the water’s edge. Princess seams give built-in volume and support; with a rear strap system sits between your shoulder blades, so it won’t shift when you move.
If you've been looking for a 2-piece that doesn’t ride up, dig in or let you down – this is it.
Made with ECONYL®
The Baltic top is made from ECONYL® regenerated nylon – a soft, supportive performance fabric made using ocean plastic waste. It’s sun-protective (UPF 50+), chlorine resistant, and dries fast so you can swim comfortably, again and again.
