Shark-fin design: gentle arm room for growing movers

The standout shark-fin sleeves give tiny arms room to stretch and wiggle, encouraging self-soothing and easing the shift from a snug wrap to a wearable blanket. This design supports a familiar, secure sensation as your baby learns to settle themselves, night after night.

Snug yet hip-friendly: a thoughtful balance

The fit is snug around the torso with a tightened waist to mimic the cocoon-like feel many babies know from the womb, while the hems remain loose enough to support hip movement and growing joints. This balance helps your baby feel secure while preserving flexibility for leg and hip movement.

• Top closure keeps warmth in and bottom opening simplifies diaper changes.
• Zip protector guards delicate skin during zipping.
• Hip-healthy design with looser hems promotes comfortable movement as your baby grows.
• Soft, breathable layers combine bamboo rayon, cotton, and fluffy fiber for real comfort.

Whether you are finishing a nighttime routine or venturing out on a chilly evening, this swaddle sleep sack offers a practical, comfortable option. The materials are chosen for softness and breathability, while the thoughtful details help busy parents manage nights with less fuss. Use it as a transitional garment from a wrap to a wearable blanket, and observe how the balance of warmth, movement, and security supports your baby sleep rhythms. Note that individual results vary, and temperature guidelines are offered to help you tailor layering to your baby needs.

Practical care and use

Care is straightforward: gentle washing and air drying help maintain softness and shape, keeping the 2.5 tog warmth consistent over time. With the bottom zipper and top closure, dressing and undressing your little one becomes quicker, supporting your routine on late nights or busy mornings.
