• Safety First, Always: Sleep easy knowing our sleep sacks are designed with your baby’s safety in mind. All of our products are rigorously tested by a leading JPMA Certified Lab, and Certified Pediatric Sleep Consultants Approved + Used.

• Midnight Change Magic: Our revolutionary WONDERZiP® system means baby stays cozy and covered during diaper changes with our genius 4-way zipper—no more fully unwrapping sleepy babies or struggling with complicated closures.

• Cloud-Soft Comfort: Ultra-soft bamboo viscose creates a gentle microclimate against baby's sensitive skin, naturally regulating temperature within the sleep sack to prevent the sweaty discomfort that often disrupts precious sleep.

• Perfect Temperature Control: With multiple TOG options designed for different room temperatures, you'll always find the perfect warmth level for any season—ensuring baby sleeps comfortably in their sleep sack all night long.

We believe better sleep should grow with your baby. Our Sleep Sacks replace loose blankets with wearable, wiggle-friendly warmth. Our thoughtfully designed baby sleep sack collection includes:

• Swaddle Sleep Sacks that recreate that secure womb-feeling to calm startle reflexes
• Transitional Swaddle Sleep Sacks for that "not quite rolling but almost there" phase
• Sleeveless Sleep Sack options for warmer nights or naturally hot sleepers
• Long Sleeve Sleep Sacks for extra coziness when temperatures drop
• Footie Sleep Sacks that keep active little toes warm while allowing movement

Available in multiple TOG ratings (0.5-2.5) to match any season and sizes from newborn to toddler, each sleep sack is crafted from luxuriously soft bamboo viscose that feels like a cloud against delicate skin. Our OEKO-TEX® Standard 100 Certification guarantees no harmful substances—just pure comfort that creates the perfect sleep environment night after night.

Our normal order processing days are Monday through Friday 9am-5pm. Orders will not be processed on major holidays or weekends as we’ve reserved that time for our families. Orders are processed 1-3 business days after they are placed, in the sequence they are received. Expedited orders are noted with the carrier once they are shipped. This timeline is an estimate only and not guaranteed. 

During a launch or special promotions, it will likely take additional time for your order to process before being shipped due to extremely high volume. Once it ships, you will receive an email with your tracking number. 

If you place an expedited order please be aware that while we do our best to ship ASAP, orders are processed in the order in which they were received during normal shipping hours. Once processed, expedited USPS, UPS and FedEx delivery commitments will apply. 

You’ll get FREE standard shipping on full-priced orders of $100! (U.S. contiguous states only) Sale items and shipping surcharges don’t count toward the $100 threshold.

We got you! We do ship to Alaska, Hawaii, and Canada—shipping rates are calculated at checkout based on your location. While free shipping doesn’t apply, we’ll always try to get your order to you as quickly as possible.
