The Baltic are our most flattering swim bottoms yet. Designed with a high waist and supportive waistband, they give you the confidence to focus on the water – not on what you're wearing. They're part of our mix-and-match swim system, so you can find a combination that works for your body, not someone else’s. Pair them with the Baltic or Nefyn top. Or swap in the Nefyn briefs if you prefer a lower rise. Your swimwear, your way. Why you'll reach for the Baltic briefs • Core coverage - Deep waistband and high waist to support and flatter • Freedom to move - High leg cut offers comfort and flexibility in the water • No sag, no fuss - Shape-holding stretch fabric that stays put in the water • Ready for the elements - Fully lined and resistant to sun cream, salt and chlorine Find freedom in the water The Baltic briefs are designed for wild swimming in wild places – mountain tarns, river bends, and rocky coastlines. Fully lined, with a high cut leg gives you full freedom of movement and confidence to boot, while the wide waistband supports your core without feeling tight. The fabric is soft but structured. Lightweight but strong. And it doesn’t bag out when wet. They're swimwear made to fit you – and made to last. Made with ECONYL® The Baltic is made from ECONYL® regenerated nylon – a high-quality Italian performance fabric made using ocean plastic waste. It offers UPF 50+ sun protection, holds its shape wear after wear, and is designed to be kinder to the places you swim.
