All-Season comfort for growing sleepers

The merino wool lining is naturally temperature regulating, which can help your baby feel warmer on cooler nights and cooler when it’s warmer. This feature supports a balanced sleep environment when paired with appropriate sleepwear. Use the sleep bag over regular sleepwear to replace loose blankets, reducing the need for extra coverings while staying breathable and soft to the touch. The outer organic cotton layer adds a gentle, durable shell suitable for day-to-day wear and bedtime routines.
