These short-legged pajama bottoms are cut with extra ease through the hips and thighs to prevent binding during movement in bed. They are typically constructed from breathable, soft fabrics like cotton jersey, modal, or lightweight flannel. The waistband usually relies on a simple elastic casing or a drawstring to eliminate hard closures that could cause discomfort while lying down.

Insider tip
When drafting a pattern for sleep shorts, always add at least two inches of positive ease to the hip measurement compared to daywear shorts.
