Safe Sleep: This newborn sleep sack swaddle replaces loose blankets in the crib, eliminating the risk of the baby’s face and nose becoming covered, and mimicking the warm, snug feeling of the womb while providing a safer sleeping environment. Our baby swaddle gently swaddle your baby’s arms to prevent them from waving their arms and waking themselves up due to their natural startle reflex, helping them sleep longer.

It helps regulate your baby’s body temperature in a room with a temperature of 68–72°F (20–22°C). Plus, our pre-wash treatment reduces shrinkage by up to 50%, so the sleep sack swaddle holds its shape even after low-heat machine drying.
Adjustable Design: Even first-time parents can master this newborn swaddle with ease! Our adjustable wing design lets you customize the fit in just a few simple steps. Choose from three swaddling styles with this versatile sleep sack swaddle: 1) Arms-in for calming startle reflexes, 2) One arm out for self-soothing exploration, and 3) Both arms free for a smooth transition to a baby sleep sack.

Swaddle Sleep Sacks for 0-3M, 100% Cotton
I recently picked up this two piece swaddle set as a gift for a newborn and it is a really nice choice. The fabric is made of one hundred percent cotton so it feels very soft and gentle which is perfect for sensitive skin. It is designed to be breathable and helps keep a comfortable temperature throughout the night. I really like that the bottom is nice and roomy to allow for healthy movement while still feeling snug and secure.The adjustable wings make it very easy for new parents to get a perfect fit every single time without any hassle. You can even choose to have the arms in or out depending on what works best for the baby. The two way zipper is a huge help because it lets you handle quick changes from the bottom without having to fully unwrap everything. It comes in a beautiful gift box and is a very simple and practical present for any new arrival in the family.

Quality and convenience for a great night’s sleep
For a newborn swaddle set, the most critical factors are safety (the “snug” factor), diaper change accessibility, and the softness of the cotton. Since these are 100% cotton and come in a 2-pack, they are likely the versatile “staple” every new parent needs.A total lifesaver for the newborn stage! These 100% cotton swaddles provide just the right amount of compression to soothe my baby’s startle reflex without being too restrictive. The 0-3 month size fits perfectly—snug around the chest but with plenty of room for healthy hip movement. Since using these, my little one is sleeping in much longer stretches. If you’re a tired parent looking for a safe, effective swaddle, this 2-pack is a must-have!I am so impressed with the quality of these sleep sacks. The 100% cotton is incredibly soft against newborn skin and stays breathable so I don’t worry about overheating. The 2-pack is a genius idea because you always need a backup when one is in the wash. I love how easy they are to put on—even in the dark—and the quiet closures make diaper changes so much easier. They’ve held up perfectly through multiple hot washes without shrinking!

Five star product but a little pricey.
These are really nice baby sleep sacks. I got these for my grandchild, and it’s wild to see how much innovation there has been in something as simple as a baby sleep sack just since my youngest was little. It is really cool how versatile it is. I love that you have the option of swaddling your baby tightly, or you can choose to have the babies arms out and be free to moved around. I think that’s a really neat feature. I also really like the zipper guard. It helps to easy the worry about having the zipper lay against baby’s skin and possibly pinching it when zipping. You also don’t have to worry about it rubbing or causing any irritation to babies skin. Another thing I have not seen on other sleep sacks is the fact that the zipper is a 2 way zipper and you can easily change the diaper without having to remove the whole sleep sack. That is so helpful and such a smart design feature. My other favorite thing is the fact that there are 2 Velcro latches instead of one. I feel like that just holds it closed more securely and there is less of a chance that it could pop open. The only reason I’m going to deduct a star is because I do feel like the price is just a little high. Right now it is priced at $30 for only 2 sacks. It seems a bit on the pricey side when compared to other options. But, if you’re okay with the price , the product itself as far as quality and design is definitely five stars.

Soft, Breathable, and Perfect for Those Mid-Night Diaper Changes
I’ve gone through quite a few swaddles recently, and this Unnivoll 2-pack has quickly become a favorite in our nursery rotation. The 100% cotton fabric is incredibly soft against the skin, and at a 1.5 TOG, it provides just enough warmth for a regulated room without the risk of overheating.What really stands out to me is the 3-way adjustable design. I usually start the night with my little one’s arms fully swaddled to prevent the startle reflex, but if they get fussy, it’s so easy to transition to one-arm or both-arms out. The two-way zipper is a total lifesaver for those 3 AM diaper changes; being able to unzip from the bottom means I don’t have to fully unswaddle and wake them up just to check a diaper.The Apricot and Blue Elephant prints are adorable and haven’t faded at all after several trips through the washing machine. While the velcro is strong and stays secure, it is a bit loud, so I recommend being mindful of that if you’re trying to adjust it while they’re deeply asleep. I would definitely buy these again as a baby shower gift or for any new parent looking for a versatile, quality wearable blanket. It’s a great value for a 2-pack that actually grows with your baby’s preferences.
