Breathable 100% merino wool jersey, the 200 Oasis Long Sleeve Crewe is our best-selling base layer top.

100% Merino, the soft merino fibres regulates body temperature in all weather conditions and resists odours

Icebreakers iconic merino thermal is ideal for skiing but also all sporting activities where you need an added layer of warmth, particularly good for running and cycling through the winter months.

Icebreaker Oasis Long Sleeve Crewe keeps you warm in cool weather, breathes well in warm conditions, and only becomes softer with age. And the details of this top make it incredibly comfortable when you move, so it is an ideal baselayer under a top or ski jacket. Flatlock seams won't chaffe, a drop tail hem for more coverage, and offset shoulder seams prevent friction and are comfortable under a rucksack.
