Soft. Simple. Ease.

Size Guide

This page is a working draft for the CalmU site. Final wording will be reviewed with the brand. Claims about certifications will be confirmed before launch.

CalmU pieces are cut for ease at bedtime: room to move, without a heavy or costume-like silhouette.

How to measure

Measure your child in light clothing. Chest at the fullest point. Height standing straight. If you are between sizes, choose the larger size for sensitive sleepers who dislike tightness.
