This is the best swaddle I’ve tried. My baby is 3 months and still needs a tight swaddle but I didn’t want to buy a ton that we wouldn’t be able to use once she’s rolling over. This one swaddles her snugly but is super roomy around her legs and I love that I can leave one or both arms out later on. This is also the most secure swaddle I’ve found and she’s slept so well with it for the first three days and nights that I turned around and bought 2 more. My only complaints are that it shrunk a bit on regular wash/dry cycle and diaper changes are a little tricky with her arms secured in the Velcro. I almost have to get the diaper underneath her hands but it’s worth it for how well she sleeps otherwise.

I cannot say enough good things about this swaddle! As a new mom, I was struggling to get my baby to sleep longer stretches at night—until we found this. The fabric is super soft and breathable, which gives me peace of mind, and the fit is just snug enough to make her feel safe and secure without being too tight. What really makes this swaddle stand out is how easy it is to use. The zipper design is genius—especially during those late-night diaper changes. No more fumbling with noisy Velcro or complicated folds. I also love that it allows for natural arm movement while still preventing the startle reflex. Since using this swaddle, my baby has been sleeping more soundly, and I’ve actually been able to get some rest, too. Total game-changer in our house. Highly recommend to any tired parent looking for something that actually works!

My 2.5 month old LOVES this swaddle. I got it yesterday in the mail and used it last night and he only woke up twice (for diaper change and to feed). We used it for the morning nap today as well and he did so good. I would highly recommend this swaddle because it's so snug and makes them feel like they're being hugged. I was at such a loss cause he would unwrap himself from other swaddles and I thought he might try and fight this one too but no .. idk what it is about this one but I love the design, how it velcros, and how snug but airy it is.

I loved this so much that I got it in multiple sizes! It really does only take seconds to put it on and my baby was never able to get his arms out of it. I was also able to use it in transition mode when my baby began rolling over by unsnapping the shoulders to have his arms out. The fabric is great and has a bit of stretch to it. Make sure to attach all the velcros when washing it, otherwise it will stick to other garments and damage them (unfortunately had to experience that). Since I hang and air dry baby clothes, it does take a bit more time to dry due to lots of fabric included. I wish I found this earlier. :)

Great product and design, I liked the fabric. However, I would size up! My son is 10lb and the small was too small and the medium fits, but he will outgrow soon even though the weight should be in range for him. The picture is the medium- length is good but around will be too tight soon. He does get his arms out sometimes- I was hopeful with all the other positive reviews about containing his arms. I do like the simple design and regardless if his arms get out I do like it better than the halo design.

Went from Halo to this swaddle. We prefer this one so much more. You don’t have to turn the baby on the side to tuck the fabric with this swaddle. Our baby breaks out of this one much less and when she does, her hand is still in the zipper part so it’s still pretty contained. This will be the only swaddle we use in the future.

The best SleepSack/swaddle on the market! If you have a wiggle worm like my baby there is no escaping this contraption. I love how easy it is to use and it keeps those wiggly little arms in place. Once the baby is ready there is an easy transition for one arm to two arms out while still keeping the chest area swaddled. The mesh and material is great for Arizona weather and my baby is not too hot. The sizing in all baby clothes is a bit off in my opinion since babies are all different, so I would buy a set of all 3 and use as you see fit. I had the Halo ones for my older two kids a few years back, but this one is ten times better!

I have tried quite a few swaddles and like this one, but it has some issues. My baby manages to wiggle the whole inner strap part down off his arms when he gets upset, I assume due to the strap between the legs. The between the legs strap is also too tight on my baby, who is quite long. The shoulders seem too wide and have a lot of bulk that gets in baby's face. I really like the mesh; swaddling often leads to overheating. The fabric is soft. The price is great. Overall, I like it enough not to return it but still on my search for the perfect swaddle.
