TWOTHIRDS’ new Islands Call collection carries you off into the laid-back world of 1970s surf culture. Drawing on Hawaii and the Mediterranean, the collection pairs sustainable materials with polished design — the perfect pick for your summer look.

Women’s collection: your summer look — light, colorful, sustainable

This season centers on flowing silhouettes and natural materials. The Stora Herro shirt and Uwins T-shirt were finished with Hawaiian-inspired prints and warm colors by Barcelona-based artist Irina Muñoz (@iiiii.es) — an easy way to make your look your own.
For an airy feel, there’s LENZING™ ECOVERO™ viscose, made from sustainably sourced wood in a closed-loop production process certified with the EU Ecolabel. Wide-leg, high-waisted trousers like Varmdo and Sandhamn pair comfort with style, and work just as well with short tops or lightweight knits for an easy summer outfit.
The swimwear collection brings a fresh energy, with vintage-inspired swimsuits and bikinis made from recycled materials. A particular standout: the Ekon bodysuits in soft terry cloth — a sustainable must-have for your next beach day.
Men’s collection: grounded in nature, functional, built for the holidays
The new men’s collection pairs functionality with sustainable style. Avocado, earth, and sea-blue tones capture the connection between land and ocean — ideal for a surf trip, a holiday, or a relaxed day at the office.
Quality materials make the difference: the Blanca jacket and Taanlo trousers are made from Telatex, a premium French fabric blending organic cotton, recycled cotton, and recycled PET bottles — soft to the touch and kind to the planet.
Shorts and jackets in ripstop fabric bring durability and toughness, while shirts in a micro-waffle weave combine style with comfort. Trousers in sustainable materials like viscose and lyocell offer maximum freedom of movement.
There’s news for surfers too: two boardshort designs made from recycled polyester and SEAQUAL® let you hit the water with a clear conscience.
