Fewer night wake-ups, longer stretches of restful sleep — the Loulou Lollipop 1.0 TOG Big Dreams Sleep Bag in Mini Mathletes helps your baby sleep deeper and more comfortably.
Crafted from TENCEL™ Lyocell with spandex for stretch, this all-season sleep sack actively manages body heat and moisture to reduce temperature-related sleep interruptions, allowing for deeper sleep cycles. The fabric is hypoallergenic, moisture-wicking, and naturally temperature-regulating — a real difference-maker for babies with sensitive skin or eczema. Best suited for room temperatures of 21–24°C.
TENCEL™ Lyocell is made from sustainably sourced wood pulp using a closed-loop process that recycles water and solvents with minimal waste.
Follows Canadian Paediatric Society (CPS) safe sleep guidelines. 2-way zipper for quick midnight diaper changes. Sleeveless design for free arm movement. Hidden seams and zipper guard to reduce skin irritation. Insulated with Dupont Sorona for cozy warmth without overheating.

Our Safety Standards
- Very soft and love that it's dryer safe!
Pilling on first wash. Washed on cold + gentle and air dried but pilled really badly after the first wash. I have other sleep sacks gifted that didnt pill as much.
Hi Jocelyn, thank you for your honest feedback. We’re sorry to hear that you’re disappointed with the appearance of the fabric after washing. All of our prints are made using water-based, AZO-free dyes. With TENCEL™ Lyocell, the fine surface fibers (or “peach fuzz”) that give the fabric its signature softness and cozy feel can become more visible after washing, particularly on darker colors. We understand that this can affect the appearance, and we’re actively working with our fabric mill to find a better solution for darker-based prints. While we know this may not look the way you expected, we hope the fabric continues to provide the softness, comfort, and warmth your little one needs throughout the night. Thank you again for bringing this to our attention. It’s feedback like yours that helps us improve.
As an “arms out” type of gal, my baby has been using LouLou Lollipop sleep bags since she was quite small. We trialed various sleep sacks/bags at the time.. LouLou was the clear winner! As we transition to the 6-18 month size, we are still just as in love and impressed as we were in the early days. The sleep bag extremely soft, great fit, beautiful pattern, and just the right amount of warmth. Thank you LouLou.
So cozy, and such soft fabric in an adorable print. High quality, baby wear.
Very soft and love that it’s dryer safe!
So soft and such a cute pattern
Great sleep bag! We love it! So cozy and nice little family animals ❤️ so cute
So soft! Washes well- no shrinking
So soft! Washes well - no shrinking
I love my babies new sleep sack. The print is beautiful and the material is sooo soft. It held up well in the washer/ dryer and didn't shrink like a lot of other brands. The sack is also long and will last her for quite a while!
So soft, so cute, so cozy
These sleep sacks are soft and cozy without being too heavy. The zippers work great, and the larger toggle makes it more accessible if you have dexterity issues. However, they need to be washed carefully, as the lining is prone to rips
Butter soft! The pattern is uber cute! My baby loves her sleep sacks an the quality is always there with this brand.
Bought this as a size up after completely loving our first one! I will be ordering a second as a backup
Amazing quality. The material is super soft. Perfect thickness to keep baby warm and comfortable. The zipper zips smoothly. My baby seems to love it. I would purchase again.
Its everything we wanted. Fits very large.
All the sleepers are also amazing.
Will buy more from them in the future.
The fabric is amazing and so cozy without being too hot.
We love it ! It is his comfort to go to sleep ! We wash it often and it is still as good as new
Soft and snugs well around baby. TOG 1.0 and its thicker than I imagined. Seems to keep the baby warm. The only thing is that the metal zipper at the bottom is not covered with fabric so my LO sucks on it sometimes, Though I think metal zipper is still better than the ones with paint on it.
After one wash it looks very pilled, faded and like it has been used for years :( I am so sad as before it was washed it was a beautiful looking garnet. I washed in cold, delicate cycle with a gentle baby detergent.
Super soft! I got the 18-36m so my son will be able to use it for a while.
Very nice material quality. Baby seems to sleep well in it.
I love this sleep sack! The waffle is so soft. We love louloulolipop sleep sacks so much that this was actually our 6th one we have purchased! They wash and wear so great.
So soft, doesn’t ride up as much as other sleep sacks and doesn’t have a collar around the neck so it’s less bulky around the neck
These are my favourite sleep sacs. They wash and wear nicely. There’s no piling or fading. The prints are cute and they fit our little one perfectly. I’ve tried several other brands and these are far superior.
After a few weeks this sleep sack still feels just as luxurious as when we first took it out of the bag.
It’s soft and has a good weight to it, so I’m confident it keeps my son cozy and warm.
Lovely design, soft and quality fabric, and cozy sleep sack for my little guy.
This is my first sleeping bag from Loulou Lollipop and I am disappointed I hadn’t tried it earlier as we are on the largest size at 2 years old now! It is so soft in and out, beautiful quality and super easy to zip close
Such nice quality! I like that the filing is not your regular polyester, it's sustainable filing! Nicely done Loulou Lollipop!
Beautiful colour and quality! The family was really happen with the sleep bag.
Bought five of the Loulou Lollipop waffle sleep bags for a newborn baby gift! These are the best on the market! So warm and cozy.
Great quality! The family that I gifted this to was really happy with it.
