Use the chart below to determine your size. If you’re between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.

Fit guide:

Our three different fits - slim, regular, and relaxed - ensure that when worn together, layers move and breathe like a single garment.

Slim fit

A snug, close-to-body fit for low bulk layering.

Regular fit

Neither snug nor loose - garments that are worn solo or over other layers.

Relaxed fit

Loose-fitting layers for a more relaxing feel.
