Smart design for easy nights and growing babies

The 1.0 TOG rating makes this sleep sack a versatile all-season layer. A 2-way YKK zipper runs along the side and bottom, so you can unzip fully or from the lower half for fast diaper changes and quick line drying. A zipper garage protects baby’s face, while the arm and neck openings are sized to fit comfortably without restriction—an approach informed by thoughtful design considerations.

• 2-way YKK zipper offers full length or bottom-half opening for convenience
• J-shaped zipper style facilitates easy access and a smooth feel
• Zipper garage guards delicate skin around the chin and neck
• Reinforced stitching and quilting boost durability for daily wear
• Fabric tested against 1,000+ substances to meet high standards
• Machine washable for busy families

Roomy, grow-with-baby fit

Designed with extra leg room and longer length to accommodate kicking and movement without the sack slipping off. The 1.0 TOG is ideal for year-round use, and the design supports hip-friendly space so little movers can stretch out as they grow. Sizing includes S for 0-6 months, M for 6-18 months, and L for 18-36 months, with unisex colors that work as a practical baby shower gift or nursery staple.

In real-life nights, you may notice the fabric feels breathable on warm evenings and snuggly when the room cools down. Pair with a lightweight onesie for a versatile layer that adapts to nighttime temperature shifts without compromising comfort. While the sleep sack is designed for comfortable wear, it’s best used in conjunction with safe sleep guidelines and regular temperature checks for your child.
