Secure fit for training - with arena MaxFit Eco 4-way-stretch fabric
arena MaxFit Eco combines recycled polyamide with elastane to deliver true four-way elasticity, helping the fabric move with the body and recover shape after stretching. The composition listed is 80% polyamide and 20% elastane, where all polyamide content is recycled.
Snug support holds position during turns and sprints, reducing the need to adjust mid-session and making the briefs suitable for training and racing.
Sun and pool protection - with UPF 50+ and chlorine/salt resistance
The fabric is treated or constructed to provide UPF 50+ protection while also resisting damage from chlorine and salt water, helping preserve fibres and colour when used regularly in pools and at the sea.
Swimmers get reliable UV defence for outdoor sessions and reduced fabric degradation from regular exposure to pool chemicals and seawater.
Comfort and practical wearability - with quick-drying fabric and internal drawstring
Quick-drying properties of the MaxFit Eco fabric reduce time spent damp after a swim, while the internal drawstring allows the waist to be adjusted for a personalised fit. The brief includes a front lining and a side length of 5.5 cm for moderate coverage.
Comfortable for back-to-back training or travel, easy to pack after a session, and simple to tighten for secure wear during dives and turns.
