Swaddle Sleeves Sack™ & Mitten Sleeves Set


Get your sleep back on with the magic of the Swaddle Sleeves Sack™

As a baby sleep expert, neonatal nurse, and mom of 4, I recommend Swaddle Sleeves as a fantastic transitional product for babies!”    

-Cara of Taking Cara Babies

  • Wearable blanket designed to be worn over pajamas and can also be used with weighted sleeves removed for arms completely free or with our Mitten Sleeves attachment!

  • Hand-crafted for the highest quality with individual pockets inside the sleeves for even weight distribution 

  • Zippered sleeves are only lightly weighted so your little one can still have the freedom to roll around and pull up if desired, or you have the option of using our Mitten Sleeves at that point for additional comfort and coziness

  • Safe for tummy rollers: just replace one gently-weighted sleeve with a Mitten Sleeve

 Get a second as a gift, or as a laundry backup with our Bundle and Save option!

We love it!

"Our baby started rolling pretty early so we were forced to stop swaddling. But that Moro reflex was still strong and led to a lot of disturbed sleep for our little one. This is perfect for our baby as it stops the startle reflex and allows everyone to get restful sleep. We’re even purchasing another to use at daycare! We highly recommend this! We love it!"

Win, win for all of us!

My 3 month old hated to be swaddled and always broke free of every kind we tried. We wanted to try and transition him out of it, and we tried so many different products and none worked as well as the Swaddle Sleeves Sack! The weighted arms helped with his startle reflex and he still could have his arms free. Win, win for all of us! Day 2 it only took 5 minutes for him to put himself to sleep! I am one happy and proud mama! Thank you for a great product and coming to our rescue--just wish I would have found this sooner!"

Mama LOVES her sleep!

"I had significant anxiety about transitioning my swaddling-loving 4 month old. I bought every type of swaddle and transitional item on the market (Mama LOVES her sleep!) and this was the one that did it and had him sleeping soundlessly through the night after two days."

It really works!

We were struggling without the swaddle, countless sleepless nights. It was a nightmare… when I came across this sleep sack with weighted sleeves, and It was a God’s sent. She has been sleeping through the night since.

It’s a MUST!

We love our swaddle sleeve sack! We had to buy a second to have on hand. I love that I can help my daughters startle reflux, while being able to move freely, and have an easy way to change her diaper. This has allowed us to make a smooth transition out of her swaddle!


Swaddle sleeves are truly MAGIC. My 5 month old has been struggling with sleep ever since transitioning out of the swaddle. Her first night in swaddle sleeves… she went straight to sleep! I couldn’t believe it. Not to mention she’s slept so well every single night since we started using them. Swaddle sleeves are a life saver!!!!

Helping us transition!

We’re trying to transition out of a regular swaddle into a sleep sack, but our son has a very strong startle reflex. I’ve been dreading this for weeks but he’s been using the weighted sleeves during nap time and it’s working!! The sleeves help dampen his startle but give me peace of mind that he’ll be ok if he does roll.

Helpful Sleepsack!

We tried all different kinds of swaddles and this one has been the best! Our baby could wiggle out of any kind of swaddle and would get angry when he couldn’t reach his hands. We bought this swaddle when he turned 3 months old and it has done a great job keeping him comfortable, asleep, and happy. We’re glad he has the ability to get to his hands and has his arms free when he rolls, but isn’t awakened by any reflex movements.

Worth It

I did as many other moms do, and read the reviews. One caught my eye, her daughter was swaddled and always woke herself up by being startled. Well this is my daughter to a T. Swaddle or no sleep for anyone. So I ordered one, it came, she hated being put in it, but like magic. She would be out in a couple min. I can not recommend this enough!

Eddie was able to unswaddle very quickly

Great quality product, with and without sleeves. My grandson loves his sleep sack!

Swaddle sleeves

We purchased this in hopes to help our 6 month sleep better. He loves being swaddled but was too big to be swaddled and is rolling over. So we bought this and the first few nights were not successful but we kept using it in hopes it would start helping him and now we’re a couple weeks in a he’s sleeping so good! When I put his to sleep he stays asleep for a good 4 hour stretch (compared to waking every hour) and if he gets startled he falls right back to sleep on his own or with just a couple bottom pats.

Swaddle sleeves sac

A good alternative to the Merlin suit, I was looking for something just like this that would dampen the Moro reflex as my baby transitioned out of the swaddle at 10 weeks. He is able to move his arms and bring his hands to his face for soothing but doesn’t flail as much as when arms are completely free. My one complaint is the fold over design of the mittens should have longer material. My baby always has a finger or two that will poke out and on multiple occasions he’s able to then get his whole hand out and that would distract/wake him up. Improved fold over mitten design with more/longer material should fix this issue. See pic.

Great feedback! It’s this kind of feedback that helps us improve our products and make them even better, so thank you!

Just get it!

I didn’t realize how much my little 3 (almost 4) month old likes this sleep sack until she had a blow out, and I had to use a different name brand one… she refused to nap for the rest of the day until I had time to wash this one and put her back in it!! It’s a lifesaver. My only complaint is I wish I could buy extra sacks to zip the sleeves on to, but this is a pretty pricey product to buy a completely new one.
Also, I was worried the sleeves would be too heavy, but my baby is still able to self soothe when wearing this. It also keeps her at a good temperature and she doesn’t get too warm. Highly recommend!
