KUIU’s fit is designed around a skin-to-shell layering system, comprised of base, mid, and outer layers. Base layers are close fitting, while mid and outer layers scale larger, so they comfortably fit together in the same measured size. Once you know your measured size and the fit type of each garment, it will help take the guesswork out of building your system.
Note: If you measure between sizes, or prefer a loose or roomy fit, upsizing is recommended.
