Icebreaker Oasis

The Icebreaker Oasis is a long-sleeve merino base layer built for high-output days in the mountains. Spun from 100% Merino wool jersey, it naturally regulates temperature, resists odours and stays comfortable across changing conditions, making it a dependable first layer for alpine skiing, ski touring and cross-country sessions. The soft, breathable fabric moves with you, while flat seams reduce chafe even during long efforts.

Performance details are purposeful: a half-zip and stand collar allow quick ventilation and extra neck protection, gusseted underarms provide unrestricted reach, offset shoulder seams reduce pack pressure, and a drop-tail hem keeps the shirt in place when you bend and stretch. These features make the Oasis as suited to climbing and trail running as to cold-weather resort days, always sitting quietly under an outer layer.
