We bought the synthetic Little Mo baby sleeping bag for our 11-month-old before our tent camping trip to Norway in June. When temperatures dropped to 9°C (48°F), we were so grateful to have it. We can highly recommend it.

Safety First
Our Baby Sleeping Bags are designed to meet all AAP-recommended Guidelines for SAFE Infant Sleep so that we can be your best option for infant safety while camping or backpacking.
They have no hoods or drawstrings, and the snug, soft collar is designed to keep babies from potentially slipping inside.
Features
Warm & Cozy
Whatever the weather, the Little Mo has you covered. Our sleeping bags are puffy, fun to wear, and never get kicked off while sleeping. The enclosed footbox gives room to move their legs while keeping toes extra cozy, and the insulated draft tube helps to keep warmth in.
Premium Insulation
Our down-insulated sleeping bags use 100% RDS-certified down, which guarantees that our down comes from animals that are humanely raised, and never live-plucked or force-fed.
Going synthetic? Our synthetic fill is lofty, cozy, and performs better than down when it gets wet.
Easy Cleaning
After your big adventure, the last thing you want to worry about is a fussy clean-up. Our bags are made from a weather-resistant nylon so you can easily wet and wipe when you’re on-the-go. Once you’re home, toss your sleep sack into your washing machine for quick and easy cleaning.

My daughter is short for her 6 month age, so the sleeping bag was pretty big on her as the funny photo shows. But she seemed happy in it and slept great during our first camping trip! I know she will grow into it, so it will get a lot of use!
Our first camping experience with baby was such a success, and I attribute that to our Morrison Outdoors sleeping bag. It was 7 degrees at night, and while my husband and I were freezing, baby girl was toasty, cozy, and slept better than at home 😝
Kept her warm camping in the cold pnw springtime
We took our 6 month old baby camping in France in Spring. This sleeping bag was perfect, keeping her toasty and warm during the cold nights. Without it, we wouldn't have felt comfortable staying in a tent. Even though she is at the lower end of the age range, it fit perfectly. The zip makes nappy changes easy, and the collar felt totally sleep safe. Couldn't find anything else like this in the UK market. Highly recommend to intrepid parents who want to maintain an outdoor lifestyle with young kids.
Baby boy slept wonderfully on his first camp in his lil mo!
I bought this for my granddaughter and they used it on her first cabin camping adventure and it work perfectly. Thanks for a wonderful product
Kept our little one warm all night, and he will fit in it through next year!
Camped for two nights in cool, wet temps. The first night I took her out of the sleeping bag because she was sweating a bit. The second night it was perfect and she woke up happy and adorable as pictured. She's 14 months old, and roughly 20 lbs. I'm excited to use it on a longer trip in a few weeks when it'll be a bit colder!
Our little lady made her camping debut in Colorado. We had unexpected 34 degree weather so we definitely needed to layer up underneath the 20 degree bag. Overall great product, but a two way zipper would be a major upgrade.
My baby sleeps so well in this, she looks forward to putting it on when we are camping and loves having her legs out over night to keep herself cool.
Perfect for tent camping with our 8 month old - he was cosy and enjoyed sliding around the tent in it! I would recommend that baby is proficient at rolling before use as it’s quite big and squishy.
The sleeping bag was great! It dipped down pretty low over night but my son was able to stay nice and warm and no complaints!
Okay it is a little hilariously large on our 6 month old, but it’s snug around the neck for safety (won’t get up over her head in the night) and the elastic at the wrists is very helpful to roll up and give her access to suck on her fingers. I’m delighted with this purchase, our little lady loves being in it and didn’t overheat at all - perfectly comfortable sleeping through the night in it. I look forward to using it for camping trips this and next summer, and then hopefully having another kid and using it for them!
Why did my child sleep through the night for the first time in this sleeping bag?? We experienced gale force winds and our tent went crazy yet my son was still and unbothered in this magic sleeping bag. That is all.
Absolutely love our Morrison synthetic sleeping bag. It kept our 9mo toasty for a week-long camping trip with nights in the low-mid 40s and we hope to get much more use out of it in the next year. It’s easy to slip on right over his regular PJs, didn’t require a bunch of layering (kiddo hates being dressed and undressed) and our little one seemed very cozy. Dream wishlist if it ever gets a redesign would be a two way zipper for warmer diaper changes, little grips on the outside to make it less slippery for crawling in and holding baby, and removable sleeves for nap times (it was too hot in the tent to nap with), but it’s a solid piece of camping gear that does its job well. Would 100% purchase again.
Great fit baby stays warm and comfortable here in the Alberta Rockies no problem ! 10/10 recommend
Kept our 9 month old super warm on a few crisp spring nights around 4ºC. Although she is a quite a tall baby and will be out of this size before we try anything colder, I have no doubts she would be comfortable in colder temperatures and will definitely be buying the larger size. My only complaint is a very small one and it's that the stuff sack could be smaller. I guess it's the same sack for both the synthetic and down bags but the down bag can compress significantly smaller, by about a 1/3rd!
Thank you Morrison Outdoors for the great little Down sleeping bag for our little one! We love the option of being able to get out in the New Zealand Back country with our baby. We spent quite of bit of time in backcountry huts and tenting. We have found the sleeping bag lightweight and compact and fits well. However we how found the temperate ratings to be quite far out. We have our little one dressed in x2 merino layers then put her in sleeping bag and we find when the temp drops to around 7-8 degrees C our little one starts to get cold. We have found this a bit limiting as we were hoping for closer to 0 degrees C limit. Has anyone else found this? Thanks!
Great experience with the little Mo down insulated! My baby stawed warm for 4 nights of autumn camping!
Ce duvet pour bébé est vraiment très pratique et nous n’avons pas regretté de le prendre pour les nuits fraîches de notre voyage en vélo cet été. Nous allons acheter un sac de compression pour le compacter plus pendant le transport pour les prochaines aventures. La livraison en France c’est bien déroulé dans les délais annoncés au départ.
Love the mitts on the sleeves! A very cosy sleep. Some nights are warmer than the bag is rated for so we were worried she would overheat, but it was cool enough that she was fine. Would love a winter bag like this!
Love it!! So glad to have something to keep babe warm and that is sleep safe
This was a great sleeping bag! As soon as we opened it we could tell it was well made. It gave us piece of mind to know our little one was safe and cozy - especially because she is a tummy sleeper. We will be purchasing the next size up when she grows out of it.
We just came back from a festival with our 8 month old and even though it was so warm in the day, the nights were freezing but she stayed perfectly warm and cosy (but not sweaty or clammy) and slept through the night for the first time!! Cannot recommend enough!
Love these sleeping bags so much, they’re the only ones I’ll buy. This is our 3rd one. My only issue with the 6-18m is that it’s not long enough. At 13m my toddler is almost maxed out in length and need to size up. 6-18m is a tricky size, for me it’s more 6-12m.
Bought the down version after I realized, when I'm laying in a tent and she's too cold, I'd pay a lot for her to be warm in that moment. So why not spend a bit more before and avoid her getting cold. Worked great, she was snug as a bug in a rug. She puked on it on the third day and it cleaned up pretty well even with the limited resources we had on hand for camping. The only downside was I think her head was cold, but given the risks of suffocation I completely understand why it's not a mummy bag style.
We went to Yellowstone and our baby loved her sleeping bag! Even in her pack n play she could still be cozy and warm and slept the same as at home while camping
This is the best sleeping bag for littles. I had one for my kids when we lived in Alaska and Montana. I never worried if they were cold at night. I loved it so much it's now my go-to gift for active families.
Bought for my 14 month old son - he's on the tall side but it fitted perfectly. Nights got cool (about 6degrees) and he slept completely through! Will be sizing up when the time comes!
It works great the only complaint is that the material is very slippery and is difficult to hold a wiggle baby and easy for them to slide off their bed
We were so excited to get this sleeping bag for our 11 month olds first camping trip but were sent the 18+ size. The size mix up makes the bag unusable, and hazardous to our baby. (Read warning label) I reached out to the company and the only thing they could do was provide a return label, and once received they could send a refund or exchange. This whole process would not only miss this but our next camping trip. I’m disappointed with the customer service on a $150 sleeping bag.
Brilliant sleeping bag we’ve bought 2 sizes now, much more freedom to use for our daughter and nice and warm for her. Great shipping even over to the UK!
We took our 8 month old camping for the first time. I was nervous because the first night the temperatures were predicted to get down near freezing, but he was toasty warm in his sleeping bag sleep sack! I would recommend for any parent who plans to take a little one camping!
Love this bag im buying 2 more there perfect for all my little one's
Excellent product & high quality!
This was a baby shower gift for my best backpacking friends. Very light-weight and high quality material. Seems like the perfect outdoor baby essential, whether it is a walk on a winter day, an overnight in the mountains, or just a chilly outdoor hang, this baby sleeping bag will definitely come in handy.
Perfect for our little granddaughter! Thank you for an excellent product!
First tent camping trip with our 6 month old was a great success with the little Mo. It got pretty chilly the first two nights down in the 30s but little guy was warm and happy. As a first time Mom, I was really nervous about him being warm enough at night but the bag did the trick. Excited to get back out there and use it again.
My 7 month old loves it and so do i!
