Yoofoss Baby Sleeping Bag 0.5 Tog (12–18 Months) 2 Pack – 100% Organic Cotton Summer Sleep Sack
Product description
What it is and why parents look at 0.5 tog
A 0.5 tog baby sleeping bag is a “lighter layer” option for warmer nights. The Yoofoss 0.5 tog sleeping bags in this 2 pack are designed to keep things snug without overheating, using a sleeveless sleep sack approach rather than a full duvet-style wrap. On paper, that sleeveless design is the point: it can help with temperature regulation while still giving a clear sleeping zone.
This is aimed at babies in the 12–18 months range, so it tends to fit the stage where many children are starting to move more during sleep. If you’re tired of loose bedding and you want something that stays on, a sleeping bag is one of the most practical alternatives for the nursery.
Key takeaways (what stands out)
The standout themes here are simple and practical: organic cotton comfort, a breathable feel, and a shape that’s meant to allow movement. The bottom is sealed, which is useful because baby’s feet are covered throughout the night rather than ending up exposed.
You also get a two-way zipper design, intended to make overnight changes easier. There’s also zipper protection, which matters because irritated skin and scratchy edges are exactly the kind of small annoyances you’d rather avoid.
Worth noting: the design includes wide space at the bottom for growing legs. If your child tends to kick and wriggle, that extra room can help them stay comfortable rather than feeling restricted.
The essentials for everyday use
For day-to-day sleeping, this bag is about staying put and staying comfortable. The “sleep sack” format usually makes bedtime routines less fiddly than bedding, and the sealed bottom helps keep the fit consistent through the night.
A small micro-example: imagine you’re doing a quick nappy change at 2am. With a two-way zipper, you can usually open just enough for access without fully undressing your baby—meaning less cold air exposure and less disturbance than removing a full garment. It’s not magic, but for parents who do night changes, convenience counts.
What to know about fit and warmth (so you don’t guess)
This pack is for 12–18 months, and the size guidance provided is based on height and weight ranges: it suits 76–89 cm and 10–12.7 kg. That’s helpful because sleeping bags are often more about overall length and movement room than just age.
Because it’s 0.5 tog, it’s best thought of as a summer/spring option or for rooms that run warm. It may feel underpowered if your nursery is on the cooler side at night—so it’s worth matching tog level to your room temperature rather than buying purely by season labels.
Materials, washing, and durability
The sleeping bag is made with 100% organic cotton, described as super soft and breathable. Organic cotton tends to be chosen by parents who want natural fibres next to skin, and breathable fabrics are especially useful when using a lower tog.
On care, the guidance says it can be machine washed up to 40°C, and that it retains its shape even after repeated washing. In real life, that matters: babies can be messy, and sleepwear needs to survive frequent washes without turning into a bag that no longer fits properly.
Pros and potential limits
Pros
- 100% organic cotton, breathable for a 0.5 tog sleeping bag
- Sleeveless design intended to help reduce overheating risk
- Wide bottom space to allow leg movement
- Sealed bottom keeps feet covered
- Two-way zipper designed to make overnight nappy changes more convenient
- Machine washable up to 40°C
Potential limits
- If you need a warmer sleeping solution for cold rooms, 0.5 tog may not be enough, this is more of a lighter option than a winter-style bag.
- The product description mentions sizes by height/weight range, but if your baby sits between ranges or you’re unsure about length, it’s still something to double-check before you commit.
When it makes sense to buy (and when to skip)
This is a sensible purchase if you want a summer-friendly sleep sack for a child aged 12–18 months, and you prefer a lighter, breathable layer over loose bedding. It also suits families who do night-time nappy changes and would like a zipper setup that’s meant to reduce disruption.
It may not be the best match if your nursery is consistently cool at night, because the 0.5 tog rating suggests lighter warmth only. Also, if you’re expecting a thicker, duvet-like warmth level, this is more “lower tog comfort” than “cold-weather insulation”.
Quick FAQ
Is 0.5 tog suitable for summer?

Does it have a zipper for night changes?
Yes. It uses a two-way zipper design that’s intended to make overnight nappy changes more convenient.
Can it be machine washed?
It can be washed in a machine up to 40°C, and the description says it keeps its shape after repeated washing.
Will it cover baby’s feet?
The bottom is sealed, so baby’s feet should stay covered during sleep.
Is the 12–18 months size based on age or weight too?
The guidance includes a size range by height and weight (76–89 cm, 10–12.7 kg), not only age.
Final verdict
It’s worth considering if you’re after a breathable, organic cotton 0.5 tog sleep sack for the 12–18 months window, especially if you want a bag that covers the feet and makes night changes easier. Just don’t expect it to replace a warmer winter option if your home runs cool—this one is more about lighter, summer-type comfort.
