Safe Sleep for Little Explorers—Rain, Shine, or Snow

The Little Mo is the world’s best sleeping bag for adventuring with infants and toddlers. Whether you’re backpacking into the high alpine or enjoying a backyard campout, the Little Mo ensures your baby stays warm and safe without the bulk of traditional blankets.

Choose Your Adventure

Use the buttons above to select the insulation that fits your family's camping style:

  • 20° Down (The Ultralight Choice): Filled with premium 650-fill power RDS-certified HyperDry down. This is our warmest and lightest option, weighing just 9 oz and compressing to the size of a water bottle. Ideal for backpacking and chilly three-season nights.

  • 40° Synthetic (The Versatile Choice): Filled with plush, hi-loft polyester insulation. This version is a parent favorite for car camping and damp climates because it maintains warmth even if it gets wet. It is easy to wash, hypoallergenic, and perfect for temperatures down to 40°F.

Core Features (Standard on All Models)

Adjustable Cuffs: Every Little Mo now includes our signature fold-over cuffs. Keep hands tucked in for maximum warmth at night, or flip them open so your baby can play or self-soothe.

Designed for Safe Sleep: Our sleeping bags have no hoods or drawstrings to meet AAP guidelines for safe infant sleep. The snug fleece collar and secure fit prevent your baby from slipping inside the bag.

The "Inverted" Zipper: Our zipper opens from the bottom up, making midnight diaper changes a breeze without letting out all the precious body heat.

Grows With Them: A tapered fit and adjustable length ensure a cozy environment for babies from 6 to 18 months (minimum 15 lbs).

Durable & Soft: The PFAS-free 1.1oz Ripstop Nylon shell is buttery-soft against baby’s skin but tough enough to handle tent life.

 

The Little Mo Baby Sleeping Bag is for babies 6-18 months, weighing 15 pounds (6.8kg) or more, and between 24-34in (61-86cm) long.

Adventure Awaits

The original, award-winning Little Mo Baby Sleeping Bag. Warm, packable, and ready for adventure anywhere you want to go.

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.

Customer photo review of Little Mo Baby Sleeping Bag (6-18 months)

Couldn’t be happier with this purchase! We just finished a week long camping trip using it and my daughter slept just like she does at home; I was very worried about the “learning curve” as she sleeps on a regular mattress and doesn’t use a sleep sack at home, but she took to the bag immediately. Stoked and will be purchasing the next size up when the time comes. Thank you!

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.

Customer photo review of Little Mo Baby Sleeping Bag (6-18 months)

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 😝

Customer photo review of Little Mo Baby Sleeping Bag (6-18 months)

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.

Customer photo review of Little Mo Baby Sleeping Bag (6-18 months)

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.

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.

Customer photo review of Little Mo Baby Sleeping Bag (6-18 months)

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!

Customer photo review of Little Mo Baby Sleeping Bag (6-18 months)

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.

Customer photo review of Little Mo Baby Sleeping Bag (6-18 months)

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!

Customer photo review of Little Mo Baby Sleeping Bag (6-18 months)

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!

Little Mo Baby Sleeping Bag (6-18 months)

Store owner replied: Thank you so much Caroline for your review and feedback.  What we have are recommended temperature ranges, which we developed based on sleeping bags with similar temperature ratings combined with our own testing and experience. There is definitely some variability kid to kid, but in general we find 20°F to be the absolute lowest we recommend for the 20 degrees down sleeping bags, and anytime temperatures get around freezing or below we recommend having good hats, extra layers, and well-insulated sleeping pads available as well.  Most people find our sleeping bags to be warm and comfortable. If you wish to return your sleeping bag for review or want to discuss this further, please reach out directly to us at hello@morrisonoutdoors.com.

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.

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.

Customer photo review of Little Mo Baby Sleeping Bag (6-18 months)

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.

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.

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

Little Mo Baby Sleeping Bag (6-18 months)

Store owner replied: Thank you Daniel for your review and feedback!

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.

Little Mo Baby Sleeping Bag (6-18 months)

Store owner replied: We’re very sorry for the size mix-up and completely understand how frustrating and disappointing this was, especially before your baby’s first camping trip. Safety and correct sizing are extremely important to us, and we’re sorry this caused the sleeping bag to be unusable for your trip. When you reached out the evening before your trip, our team replied first thing the next morning, but unfortunately there was not enough time to get a replacement to you before you left. We understand that still did not solve the problem in time, and we’re truly sorry for the inconvenience this issue caused. We appreciate you bringing this to our attention and will be reviewing this internally to help prevent it from happening again. We’d still like to make this right with either a refund or exchange, and our customer service team will continue working with you directly.

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!
