Buying Guide

TOG and temperature suitability

Choose a sleep sack with an appropriate TOG rating for your climate and nursery temperature; 1.0 TOG is generally suitable for moderate indoor temperatures

Fabric and breathability

Select breathable, soft materials—bamboo viscose is common for its softness and moisture wicking, which helps regulate baby temperature overnight

Closure type and diaper changes

Two‑way zippers simplify nighttime diaper changes and reduce fully undressing the baby, making overnight care faster and less disruptive

Fit and sizing

Ensure a snug fit around the neck and armholes with enough room at the hips and legs to allow natural movement and hip development without excess fabric

Safety standards and sleep guidelines

Confirm products follow current safe sleep recommendations—no loose bedding, proper neck/armhole fit, and materials compliant with infant sleep safety guidelines
