The 200 Oasis shorts are made from Icebreaker's most versatile jersey fabric, a blend of merino wool. They are designed to be worn as a base layer for all types of activities, year-round. The shorts feature merino wool's natural stretch, breathability, and odor resistance, providing partial insulation regardless of the season. The shorts are made from a renewable resource and are naturally odor-resistant, keeping you cool when it's hot and warm when it's cold. They also allow your skin to breathe for long-lasting comfort.
