The benchmark against which all others are measured, the 200 Oasis Long Sleeve Shirt is Icebreaker's best-selling base layer – a versatile top for year-round layering and daily comfort. The soft merino jersey is breathable, stretchy, and naturally odor-resistant, while flat seams prevent skin irritation. Inspired by nature, Icebreaker leverages the functional properties of natural fibers to provide an alternative to synthetic clothing. Merino wool is an annually renewable fiber that naturally resists odor. It cools in heat and warms in cold, allows the skin to breathe, and ensures long-lasting comfort.

Soft merino fibers regulate body climate in all weather conditions and naturally combat odor formation. Offset shoulder seams and flat seams prevent chafing, while the extended back provides extra coverage.

100% pure merino, temperature regulation, breathable, moisture management, naturally odor-resistant, warm when wet.
