Insular Baby Swaddle Sacks Seagull – 3-Pack Soft Cotton Sleep Sacks for 0-6 Months

Soft, breathable cotton swaddle sacks for cozy newborn moments

With Insular, every swaddle experience starts with 100 percent premium cotton that feels gentle on delicate skin. The Seagull design comes in a convenient three pack, offering soft sleep sacks for babies from birth through the first half of their first year. The fabric’s natural breathability helps regulate comfort, while the absence of irritating fasteners keeps the feel soft along the tiny shoulders and arms.

These swaddle sacks are designed for safety and ease. No zippers, snaps or buttons means fewer elements to worry about, while the adjustable wings provide a secure, snug fit that can be tailored as your baby grows. The resulting gentle, womb-like embrace can help create a soothing environment for calmer nights and shorter tries to settle down, which many parents find enhances bedtime routines.

Fit and sizing at a glance

The set is designed to cover both newborns and younger infants. It fits babies in the 0 to 3 month range (approximately 6.6 to 11 pounds) and extends to the 3 to 6 month range (approximately 11 to 22 pounds) as they grow. This range helps parents plan ahead while staying flexible as baby progresses through growth spurts. The result is a versatile sleep solution that can travel with your baby from early days to mid infancy without needing to swap sizes immediately.
