Too hot to sleep? Keep cool every night with this cooling long sleeve:

• Engineered for ultimate moisture-wicking, drying three times faster than cotton
• 8x more breathable than cotton
• Twice as soft as cotton

“Even a small rise in body temperature during the night can have a major impact on our sleep. When we overheat, the b+G8:G9ody struggles to enter and maintain deep sleep — heart rate and stress levels increase, we wake more often, and true recovery becomes impossible. Dagsmejan’s Stay Cool collection is designed to counteract exactly that. Its intelligent cooling and moisture-management technology helps the body release excess heat and maintain the optimal temperature for restorative, high-quality sleep — night after night.”
— Dr. med. Lutz Graumann, Specialist in Sports Medicine, Nutrition & Regenerative Medicine.
