Size Guide
Sizes on this site are the sizes on the label — US sizing, shown as-is. These are the body measurements behind each size, so you can pick once and not guess twice.
Women
InchesChest, waist and hip are body measurements, not garment measurements. If you land between two sizes, take the larger one for fleece and outerwear.

Kids, toddler & baby
InchesHeight and weight matter more than age for little ones. If a child is at the top of a band, size up — the next band costs the same and lasts longer.

| 3–6 M | 23–27" | 12–17 lb |

How to measure
Use a soft tape, keep it level, and measure over undergarments rather than over clothes. Stay relaxed — do not pull the tape tight.
- Bust / chest
- At the fullest point, arms relaxed at your sides, tape level across the back.
- Waist
- At the narrowest point, usually just above the navel.
- Hips
- At the fullest point, feet together.
- Inseam
- From the crotch seam to the hem of a pair of trousers that already fits.
