The M311SPL3000 swim trunks celebrate Sundek's heritage with the iconic rainbow on the sides: made from Econyl® regenerated fabric, they combine the brand's distinctive symbol with environmental sustainability. These eco-friendly men's trunks with an adjustable waist are perfect for those who love Sundek style.
The rainbow on the sides is the detail that makes these boxers instantly recognizable. Positioned on the side rather than the back, this iconic element creates a distinctive graphic effect.

Econyl® regenerated fabric is an innovative nylon made from recovered waste, such as abandoned fishing nets and textile scraps. It offers the same performance as traditional nylon—strength, elasticity, and quick drying—while drastically reducing its environmental impact. A timeless design that keeps pace with the times.

The adjustable drawstring waist ensures a personalized fit, while the contrasting drawstring adds a distinctive touch of style. This color detail completes the design and allows for a personalized fit. With a 23 cm outside leg length (in size M), these boxers offer a classic and versatile fit, perfect for those seeking more coverage than briefs but more freedom than boardshorts. The ideal length for swimming, training, and relaxing on the beach.
