The 200 Oasis Long Sleeve Half Zip is a super comfortable women's base layer top that provides the perfect foundation for your cold weather layering system. Thanks to Icebreaker's proven merino jersey, the Oasis is breathable, insulating and odor resistant.
The classic zippered collar makes layering easy and allows for quick temperature regulation.
Underarm gussets and set-in sleeves also allow for freedom of movement, while tucked shoulder seams and flatlock seams prevent chafing.
