The benchmark by which all others are measured, the 200 Oasis long sleeve shirt is an ultra-comfortable base layer that forms the perfect foundation for a cold-weather layering system. This top is made with icebreaker's proven 100% merino wool jersey, making it breathable, insulating and naturally odour-resistant. Flat seams also ensure a soft feel. Inspired by nature, icebreaker makes use of the functional properties of natural fibres to offer an alternative to synthetic clothing. Merino wool is an annually renewable fibre that naturally counteracts odours. It cools in the heat and warms in the cold, allows the skin to breathe and ensures long-lasting comfort.
