Long Sleep Sack ≠ Too Big Sleep Sack!
Room for Healthy Hip Development
TotBasic Baby Sleep Sack is designed with extra length for comfortable movement and healthy hip development, allowing your little one to stretch, wiggle, and sleep comfortably.
To ensure a proper fit:
- Make sure the collar is pulled up to avoid covering the airway when your baby is lying on their back
- The collar should pop down easily for a secure fit
- As long as the sleep sack fits well around the chest, arms, and neck, the extra length will give your baby plenty of room to grow

Color: okay so I liked in the product photos the colors looked vibrant but you never know what you’ll get. Well, this was even better than expected! Those deep blues are beautiful up against the white. And the “muted†colors of the animal one I purchased against the white gave off the exact vibe I was expecting. Soft and beautiful, as I’m not one for super bright and chaotic colors!Material: I was expecting an almost cheap “active†feeling material, which I’m not a huge fan of but I saw the design and colors of these sleep sacks and bought them on impulse for the look. But when they say these things are BUTTERY they are not lying! These are soooo soft. Thick enough to keep my baby warm and to hold up over time but thin enough that he won’t overheat, even with wearing clothing underneath. It’s also got a good stretch to it.Fit: I purchased the “small†my son is 3 months old, 24.5 inches long, and 16 pounds. This fits him pretty well, with plenty of room to grow into.Quality: the fabric is amazing quality, I cannot speak to how the zipper will hold up or how it will handle washing and drying, but I’ll update my review for that later.Features: two way zipper! If you’re the one doing all the diaper changes (especially at night) you know the bottom and top zipper features are a life saver. They also have the cloth at the top and bottom to cover the zippers so they don’t bother your baby. It also comes with a mesh bag for washing and drying to keep them safe, which is awesome because it gives me peace of mind that they’ll hold up and I can use the bag for lots of other items I already own!Overall: I am SO excited about these, if the quality holds up - I absolutely will be ordering more for my baby and as gifts for my friends’ babies.Complaints: my only complaints are that shipping took foreverrrrrr but I knew that when I ordered it, they actually came a couple days earlier than the anticipated delivery date. I just wish they wouldn’t have taken so long in general. That aside, they’re worth the wait. The other complaint is, I wish there were more prints, especially boy-ish ones, because I love these so much 🤣Small update: the stretch I mentioned is a bit of an issue with us, my little one like to kick around and he gets all bunched up in it, pulling the neck wayyyy down from kicking around so much lol. I think when he’s taller it won’t be much of an issue because he will be long enough that the kicking and pushing won’t pull the entire top down. Still love these.

The prints on these are so cute and magical! They are a soft, jersey-like fabric that has a slight stretch to it, with a good quality zipper. It's lightweight for warmer temps, but keeps baby warm enough while wearing fleece PJs. Overall, lovely little sleep sacks!

We have been really enjoying this so far! It is a double sided zipper, which is useful for night changes. The fabric is sooooo soft but also seems pretty breathable. It is quilted on the inside. If you are concerned with hip room, I included a pic comparing the width of this to one of the Burts Bees Beekeeper sacks. Although the BBs are slightly roomier in the hip/feet area, these still have plenty of room!We are currently transitioning baby out of swaddles now that he’s 2.5 months, and we had been using this for naps but a transitional swaddle at night. Last night was the first time using this one at night and he did great! We keep our house at 68 at night; we had him in a footed onesie and this and he was perfectly comfortable!

My wife and I love these for our twin girls. The patterns are beautiful, the material is super soft and they seem to be very well made. They have a double zipper, which is a useful feature not all sleep sacks have. We have ordered several of these as the girls grow, and have also purchased some of the heavy weight version for the winter months. Would absolutely recommend.

Soft and long and stretchy enough. The only downside my baby can unzip them so I have to put them on her inside out to prevent this.

Love these. So soft and keeps my daughter warm in the winter. Her room runs between 66-70° F in the winter and she is perfectly warm with just long sleeve and pants underneath. I actually bought two! They hold up really well after three months and constant washing.

I have a 5mth old who has never been able to self sooth and put himself to sleep, finally does. For 5 months I have been holding him, rocking him and patting him for him to sleep. It’s been night 2 with this sleep sack and it’s done ME WONDERS! His startle reflex has gone down a TON and it’s because his age.It’s light weight and thin BUT warm enough perfect for states that are hot like Florida. I don’t worry about him over heating AT ALL.Incredibly soft so it doesn’t irritate him. He’s pretty sensitive to fabrics and materials so this does not make him break out. There isn’t anything rubbing on him harsh.The zipper is quiet so for those night changes it doesn’t wake him up. Which a lot of other sleep sack does!It fits him like a glove he is 18lbs 26inches and he wears a size 6-12 months.It’s also really cute. For the price and for 2 is a STEAL. This is the best sleeping gear I’ve gotten for my baby that ACTUALLY works.

Bought these for my new born. she is now 7 months and she is fitting pretty good in them. I love how they came in a 2 pack as we are in need of a new one if it gets dirty. I love the zipper system and how it has two. It is easy in the night to zip from the bottom so she is not fighting to get out of it. Makes changing her in the night so much easier. It is very light weight and with summer coming up they are going to be great. They are also very soft and have lots of room for her to grow with them. Honestly, these are one of the best buys that I have made on amazon!

These definitely exceeded my expectations based on how reasonably priced they were. The fabric is light and soft, zipper is sturdy and the colours and designs are really fun. Definitely worth getting.

This is a great sleeping beg, very soft and beautifulI only give it 4 star because the size small is very big for a small baby. It should be 6 month plus

So happy with this purchase. The sleep sacks are stunning and extremely soft. It came with a mesh bag for washing. I recommend for the warmer season so the little ones are comfortable and safe while sleeping.
