Designed for women, this long-sleeve base layer is ideal for hikers, snow sports enthusiasts, and those who enjoy daily outdoor activities who are looking for a versatile garment that doesn’t compromise on comfort. The Icebreaker M 200 Oasis LS V-Neck is made from 100% merino wool, spun from fibers hand-selected for their durability and softness. Its V-neck and slim fit give it a tailored silhouette that’s just as comfortable under a ski jacket as it is for everyday wear.

The Icebreaker M 200 Oasis LS V-Neck Midlayer: A Natural Fiber Designed for Performance

The fabric has a weight of 200 g/m², placing it in a mid-range weight suitable for cool temperatures without causing overheating during physical activity. Merino wool naturally regulates body temperature by absorbing and releasing heat in response to changes in activity, while wicking away moisture to keep the skin dry. Its natural odor resistance reduces the need for frequent washing—a real advantage on multi-day trips. The fibers have a micron count of 18.9 µ, a diameter fine enough to ensure a soft feel against the skin without any itchy sensation.

A design crafted to minimize irritation and preserve freedom of movement

The construction details directly contribute to comfort during active use. Flatlock seams and offset shoulder seams reduce friction points, which are particularly sensitive under a backpack or layers of ski clothing. Gussets under the arms round out the design, allowing for a full range of motion without the fabric pulling. The back hem, slightly longer than the front, provides better coverage during forward bends, preventing exposure in the lower back.

A Material Choice That Respects Natural Resources

The merino wool used is naturally renewable, recyclable, and biodegradable under certain conditions. It is free of plastic microfibers and petroleum-based synthetics, which sets it apart from conventional base layers in this specific regard. Machine wash cold on a delicate cycle; do not use fabric softener or tumble dry, to preserve the fiber’s structure over time.

The Icebreaker M 200 Oasis LS V-Neck Midlayer is available in two colors and five sizes, from XS to XL, for a precise fit.
