Measure yourself:

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. If your measurements for chest and waist correspond to two different sizes, order the size indicated by your chest measurement for tops and your hip measurement for pants.

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.
