arena, the global Italian swim brand, is moving forward on two fronts this season: refreshing its pool style with a new two-tone collection and a renewed momentum in sustainable swimwear through continued partnership with The LYCRA Company.
Bold Lines: A Fresh Take on Poolside Style
Bold Lines is a new collection of women’s one-piece swimsuits designed for fitness swimmers who want performance and style in one unique silhouette. Built on contrasting and vibrant solid colours, free of prints or graphic patterns, the Bold Lines collection lets colour do the talking, with distinctive medium-width trims that outline each design for a clean, two-tone effect.
The line includes five colourways, each pairing two solid tones from the season’s palette: Black-Asphalt, Black-Calypso Coral-Violet, Sage-Arctic Lime, Water-Violet and Neon Blue-Fuchsia. Every style is made from WaterFeel Eco, arena’s comfort-stretch fabric built with 80% recycled polyamide sourced from recovered yarns and industrial waste.

Bold Lines anchors arena’s “Swim Bold or Go Home” campaign, launching in early October.
Expanding the Partnership: arena Grows Its Commitment to Renewable Materials with The LYCRA Company
arena is also continuing its partnership with The LYCRA Company, promoting the use of renewable LYCRA fibre as part of a broader push toward more responsible materials across its swimwear line.
Renewable LYCRA fibre is made with 70% renewable content derived from field corn grown in the U.S. Midwest and carries USDA Bio Preferred certification for its bio-based content. According to a 2026 comparative life cycle assessment commissioned by The LYCRA Company, the fibre has the potential to reduce its carbon footprint by up to 45%* compared to conventional, fossil-based spandex, while delivering the same stretch, recovery and fit performance swimmers expect from LYCRA fibre.
arena first brought renewable LYCRA fibre to market in its Vita Life collection, available now, pairing it with ECONYL® regenerated nylon made from ocean waste. The expanded partnership marks the next step in bringing that renewable fibre further into arena’s line, while Bold Lines continues to feature MaxFit Eco, the brand’s recycled-polyamide fabric.
Together, these unique collections are designed to give fitness swimmers more style, performance, and choice in technical swimwear that is designed to look as good as it performs.
