Yoofoss Baby Sleep Sack 6-12 Months TOG 2.5 Winter

Yoofoss Baby Sleep Sack 6-12 Months TOG 2.5 Winter Baby Wearable Blanket offers warmth with 100% Organic Cotton and a safe, snug fit for peaceful nights.

Designed for cooler months, the Yoofoss sleep sack uses 100% Organic cotton fabric with fluffy polyester filling and TOG 2.5 warmth. Its 3-layer breathable construction and sleeveless cut help regulate temperature, reducing overheating risk while keeping your baby cozy. The safety-focused design features a carefully sized neckline and a snug fit to prevent slips and support natural hip development.

Safe sleep is supported by CPSC-certified design, a secure neckline, and a roomy leg area that allows natural hip movement. The long quilted construction distributes the fill evenly, improves durability, and helps prevent lumping while withstanding hundreds of washes. A smooth 2-way zipper simplifies diaper changes, with top zipper protectors guarding the jaw and avoiding irritation during nighttime. For colder rooms, you can layer this sleep sack with warmer sleepwear and choose from S to XL as listed in the size chart.

Room temperature guidance from the product notes suggests 61°F–68°F for optimal comfort, and the included size options cover infants and toddlers from S to XL (S 0-6 Months, M 6-12 Months, L 12-18 Months, XL 18-24 Months). Always refer to the size chart before ordering to ensure a proper fit.
