Buying Guide

Choose the right tog for room temperature

TOG ratings indicate warmth—look for lower TOG (around 0.5–1.0) for warm rooms and higher TOG for cooler environments to avoid overheating or underdressing

Prioritize breathable, natural fabrics

Materials like bamboo viscose and light cotton wick moisture and regulate temperature, which can improve comfort and reduce overheating risk during sleep

Check zipper style and access

Two-way zippers and front-opening designs simplify nighttime diaper changes and make swaddle-to-sleep-sack transitions easier for caregivers

Consider swaddle-to-sleeper transition features

Options with arms-up or swaddle-compatible designs help babies move from swaddling to wearable blankets while preserving a familiar sleep feel

Match fit and sizing to your baby

Ensure the sleeping bag size offers enough leg room for hip development without excess fabric around the face; consult sizing charts and weight/age guidelines
