Quick answer
Both sleep sacks help active sleepers, but the Flying Squirrel Pajama stands out with its wearable blanket design and AAP-aligned safety. Choose it if your toddler needs freedom to move and a cozy fit that won't ride up.
Design and Safety Considerations
The Flying Squirrel Pajama is designed as a wearable blanket, which means it replaces loose bedding and reduces the risk of covering your child's face. Its loose fit gives plenty of room to grow, while ribbed cuffs at the wrists and ankles keep the fabric in place—no more hiking up during sleep.
The Zipadee-Zip, on the other hand, is a popular sleep sack with a starfish-like shape that allows arms and legs to move freely. It also follows safe sleep guidelines, but the key difference is in the fit: the Zipadee-Zip tends to be more fitted through the torso, while the Flying Squirrel offers a roomier, blanket-like feel.
Comfort and Fabric
The Flying Squirrel Pajama uses breathable fabric with gentle stretch, which helps regulate temperature and allows for natural movement. The loose fit is great for toddlers who toss and turn, and the stretch ensures comfort without being restrictive.
The Zipadee-Zip is typically made from a soft, stretchy fabric as well, but the fit is more snug. Some parents find the Zipadee-Zip's fitted design helps some babies feel more secure, while others prefer the extra room of the Flying Squirrel for active sleepers who need more space.
Trade-Offs at a Glance
- Fit: Loose vs. Fitted: The Flying Squirrel has a loose fit with plenty of room to grow, while the Zipadee-Zip is more fitted through the body. Choose the Flying Squirrel if your child prefers a roomier feel; choose Zipadee-Zip if a snugger fit helps your child settle.
- Fabric: Stretch vs. Softness: Both use breathable, stretchy fabrics, but the Flying Squirrel emphasizes gentle stretch and a blanket-like feel. If you prioritize a wearable blanket experience, the Flying Squirrel is the stronger choice.
- Safety: AAP Alignment: The Flying Squirrel is designed based on safe sleep recommendations from the American Academy of Pediatrics (AAP). If AAP alignment is a top priority, the Flying Squirrel has a clear advantage. Always check the latest AAP guidelines and your child's age and size before selecting a sleep sack.
