FIEMOL Baby Sleep Sack 12-18 Months | 2.5 Tog Cotton Winter Sleeping Bag

Cozy, breathable winter wear for toddlers

Meet the FIEMOL Baby Sleep Sack for 12-18 month-olds—a cloud-soft cocoon built with premium cotton on the outside and inside, plus a light, fluffy filling. The result is a gentle touch against skin combined with improved airflow, helping your little one feel comfortable through the night and during naps.

This winter wearable blanket is designed to be worn in the room’s typical chill. By layering with pajamas or a bodysuit, you can tune warmth to your child’s needs without sacrificing freedom of movement.

Warmth you can feel

The 2.5 tog rating suits rooms around 50-68°F (10-20°C). In cooler spaces, add a bit more clothing; in warmer corners of the house, a lighter layer may be enough. The aim is a steady, comforting warmth that adapts as your child moves.

• Premium cotton exterior and interior provide a soft, skin-friendly touch.
• Fluffy filling adds warmth while remaining breathable and light.
• Airflow-focused design helps prevent overheating without sacrificing coziness.

Roomy, development-friendly design

The sack’s generous cut supports natural leg movement for kicking and stretching, which can align with early hip-healthy play patterns. A snug neckline and sleeveless design help keep the sack in place while allowing free arm movement.

• Wide body space supports active movement during sleep and playtime.
• Snug neck opening helps prevent the sack from sliding up.
• Sleeveless design enhances airflow to reduce heat buildup.

Smart, parent-friendly features

Designed for practical nights, this sleeping sack uses a 2-way zipper for easy diaper changes without fully undressing your child. A zipper protector at the top protects delicate skin, making nights smoother for both baby and caregiver.

• Bottom zipper access enables quick diaper checks and changes.
• Top zipper guard minimizes chin irritation during movement.
• Soft fabric around the zipper reduces pull and snag risks.

Fit, care, and sizing options

Choose from four sizes: 0-6 months, 6-12 months, 12-18 months, and 18-24 months. If between sizes, consider sizing down for a snug, secure feel. The sack is machine washable up to 40°C (104°F) for easy care.

Used in everyday bedtimes, car rides, and calm nap moments, the FIEMOL Sleep Sack can become a trusted part of your toddler’s routine, offering warmth, comfort, and freedom of movement without fuss.
