The Kari Traa Else Half-Zip is a 100% Merino wool half-zip women’s baselayer top inspired by our Norwegian heritage and knitting traditions. We’ve given this classic pattern an upbeat modern twist to give you fresh, fun fashion. Tone down or spice up your look depending on color choice. This half-zip also blends old-school natural material – ethically sourced Merino wool – with modern stretch fabric mapping for warm, flexible, next-to-skin comfort. OEKO-TEX® 100 certification means that the main fabric poses no harm to human health.
