Soft, breathable comfort for tiny sleepers

Key benefits at a glance

• Safety-first design meets CPSC guidelines, helping reduce the risk of loose blankets in the crib.
• Premium fabric: 100% combed cotton feels soft against delicate skin and remains breathable for comfort.
• Durable and easy to care for: Pre-washed to reduce shrinkage by about 50%, maintaining fit wash after wash; machine washable with low-temperature drying.
• Diaper-time convenience: A full-length 2-way zipper runs from top to bottom, with a zipper guard to protect delicate skin during changes.

Designed for growth and practical use

The sleep sack comes in four sizes—S (0-6 months, 10-18 lbs), M (6-12 months, 16-24 lbs), L (12-18 months, 22-28 lbs), XL (18-24 months, 26-34 lbs)—so you can keep baby cozy as they grow. This makes it a reliable everyday essential for busy households.

Calm visuals and gentle development cues

The included sky-inspired patterns—rainbow, star, and planet—offer soothing colors (green, blue, pink) that can help create a calm bedtime vibe and provide visually engaging cues as babies begin to track shapes and colors. The design prioritizes both comfort and gentle stimulation.

Care and performance you can count on

• Lightweight and breathable: The 0.5 TOG rating is well suited for nursery temperatures around 75°F and above.
• Quick diaper changes: The two-way zipper design makes midnight diaper changes faster and cleaner, with a guard to prevent rubbing on skin.
• Grow-with-baby reliability: Pre-washed fabric helps minimize shrinkage, keeping the fit consistent over time.
