* All measurements are in inches unless noted; KUIU product pages also offer a centimeters tab.
* Measurements are body measurements, not garment measurements. If between sizes, KUIU recommends sizing up.
* KUIU's layering system is designed so base, mid, and outer layers share the same measured size.
