The Douro trunks are made from modal and cotton. Their print is bright, decorated with large, navy blue leaves arranged on a background of houndstooth, azure blue and turquoise blue chevron patterns. Their fabric is made in Europe and is dense and very resistant. The modal cotton textile is light and supple. This material preserves colors well over time. It is also known for its antibacterial qualities and the body's thermal regulation. The fabric does not wrinkle, does not twist, does not fluff and resists friction well. The inner shell is lined with 92% cotton fabric and reinforced with 8% elastane. The cut of these trunks is shorter on the thigh than classic cut boxers. It stops below the buttocks line and has a lower waist. The elastic waistband is flat and does not compress. These trunks feature the Oeko-tex guarantee. This guarantee highlights the non-toxicity of the fabrics, threads and dyes used in the manufacturing process.
