The Iona style was designed specifically for women. Iona was created on a women's design form so we could include styling features that would improve the fit and comfort for high-risk female professionals.
The Iona is a versatile garment that can be worn comfortably as a baselayer or as a first-layer garment with its long sleeves, thumb loops, and high neck (1/4 zip top), which means you will be better protected when working in the extremes.
