Sourced from the Mackenzie basin in New Zealand, the Otis Merino T-Shirt combines ultimate softness with function. Merino is nature's wonder fibre—offering breathability, thermoregulation, and natural anti-odour properties, and serves as the perfect partner for training sessions or long runs in changing conditions. Unique Rapt™ construction encases a durable nylon yarn inside the merino fibres giving the Otis the durability of a synthetic with the properties of 100% merino wool.
