How to use: Simply put on the boxer briefs like you would any other underwear. They're perfect for everyday wear or intense physical activities. Notice: Make sure to choose the right size for a comfortable fit. Avoid using harsh chemicals or bleach when cleaning. Maintenance advice: Wash them in cold water and tumble dry on low. This will help keep the Merino wool fabric in good condition and maintain its temperature regulation, moisture management, and odor control properties.
