With Bodyfit™ technology, the Icebreaker 200 Oasis Merino Long Sleeve Crew Base Layer boasts effortless performance thanks to its ability to thermo-regulate, all the while perfectly managing moisture for a fresh dry performance. Plus, because it was made in the mountains rather than in a petrochemical laboratory, the Merino wool fibre it is made with is naturally renewable, recyclable and biodegradable* (*wool tops, under certain conditions). With seams that have carefully been offset, flatlock seams that prevent chafing and underam gussets that add a touch of breathability, comfort is always guaranteed. More info
