Yoofoss Baby Sleep Sack 12-18 Months | 1.5 Tog Organic Cotton Wearable Blanket

Cozy, safe warmth with organic fabrics

The Yoofoss Baby Sleep Sack is a warm, breathable wearable blanket designed for little ones who are growing quickly. It combines two layers of 100% organic cotton with a gentle polyester fill to deliver soft, cuddly warmth without excess bulk. Certified to meet Global Organic Textile Standard (GOTS), this sleep sack prioritizes skin safety and comfort for infants with sensitive skin, while the natural fibers feel gentle against tiny bodies.

For everyday sleep, the fabric feels plush yet airy, so your baby can drift off with a balanced, cozy sensation. The combination of organic cotton and careful construction helps create a soothing environment that can make nap times and overnight sleep more peaceful for both baby and caregiver.

Seasonal versatility and smart design

With a 1.5 Tog rating, this sleep sack is crafted for moderate temperatures—roughly 69 to 73°F (21–23°C). It’s ideal for autumn, early winter, and spring, or for naps in air-conditioned rooms during warmer days. The sleeveless cut provides freedom of movement while helping regulate temperature, and the bell-shaped bottom gives growing hips ample space for natural motion.

• 1.5 Tog warmth suited to medium-room temperatures, offering a balance of coziness and breathability
• Sleeveless silhouette to reduce overheating while maintaining comfort
• Bell-shaped bottom supports free leg movement for healthy hip development

Practical features you’ll notice at bedtime

The sleep sack uses a top-tier 2-way zipper, so you can unzip from the bottom for easy diaper changes without waking your baby. A zipper garage protects the zipper’s end from rubbing against the face, keeping cheeks and chins comfy. The design comes in four sizes to fit your child as they grow: S (0–6 months), M (6–12 months), L (12–18 months), and XL (18–24 months).

• 2-way zipper enables quick, fuss-free diaper changes
• Zipper garage guards delicate skin from chafing
• Four size options help you choose the right fit as your child grows

Durability, care, and practical tips

Designed to withstand hundreds of washes, the sleep sack maintains its softness with minimal shrinkage — less than 3% after machine washing and low-heat drying. For best results, choose the correct size based on your baby’s weight to prevent the sleep sack from riding up toward the face during sleep.

• Machine washable with less than 3% shrinkage when dried on low heat
• Correct sizing helps keep the fabric in place for a comfortable night’s sleep

The breathable yet warm fabric helps create a calm sleep environment, while the roomy hip area supports natural movement as babies grow. It’s a practical choice for parents seeking a reliable wearable blanket with thoughtful details and a focus on everyday comfort.
