  100/10 recommend

  I LOVE these sleep sacks. I own 2. I cannot recommend them enough. I love that they are all season and cover a wide temperature range. We started using it as soon as my baby was big enough and it’s great this one sleep sack will be good through 24 months. It’s a pricy investment but in the long run you’re saving money by not always needing to size up or need sacks for different seasons. So many cute patterns. Easily washable and safe for your baby. The material is soft and so nice. My baby is comfy in it. Great quality.Ver másVer menos

  Warm, cozy, and economical...

  I put off buying this thing for 6 months, due to price, and now I wish I hadn't waited.Apparently, in order to keep babies from going up in flames, infant sleepers have to be either fleece (which stops being fluffy after only 3 washes), treated with fire resistant chemicals (um, no), or snug fitting (itchy!). Well, I was cheating by buying super big sleepers for my son, and just letting him sleep with floppy footies. Unfortunately, now that he is 9 months, the "snug fitting" sleepers are ridiculously tight, and he was waking up with freezing feet every night, even the fleece sleepers-- which are 20 bucks a pop where I live, and have to be replaced every month, because they pile up. Plus, he started crying whenever I zipped them up, because who on EARTH wants to sleep in a compression sack-- I certainly wouldn't. I itch when my tank tops are too tight!So I finally pressed the button and got this little gem. I've used wool baby products before, so I would encourage anyone to "lanolinize" this every few months, which helps the wool resist moisture/pee, softens it, and allows you to wash it less, and makes it hang dry quicker. However, this is as soft as Egyptian cotton and the company says it's washable, so you don't really need to. (I always handwash with a little Dr. Bronners and lanolin, though, personally).This bag has sturdy snaps (no scratchy velcro), which allow it to be comfy but form fitting on the upper body. Double snaps on the side comform to a smaller or bigger baby. Even though my son has TONS of room in the foot area to grow into, I have zero concerns that he will get twisted up in it... and he's a hard-core squirmer. Even with his constant caterpillar scooting and rolling, he's never complained or been uncomfortable in this, and when he does wake up at night, his feet are WARM, because he's basically sleeping in a giant mitten. It has a zip at the bottom for nighttime changes or, possibly, if you're kiddos feet are getting hot. There's an open/close spot at the crotch area for safety belts to go through. Plus, this saves money, because (underneath) the baby is sleeping in the same one-sies or shirts he/she would be using during the day, so you don't have to keep getting longer foot-ie pyja, or replacing the scratchy fleece ones.Don't hesitate to buy this wonderful product. It's cozy, quality construction, and economical, in the long run.Update: still going strong at 2 years, with occasional washing, but no special treatment whatsoever. It's even been thrown in the regular, high heat dryer several times, although I wouldn't recommend doing so regularly. My son sees the sack and knows it's time to "snuggle up" for bedtime. Love it!Ver másVer menos

  One Sleep Sack to Rule them All

  Love this sleep sack. Soft and comfortable. The quality feels very nice. I love that it works for a range of temperatures. So far our little one seems to be a comfortable temperature in it. It fits her fine at 10 lbs. It has underarm snaps for the tiny babies, with lots of space for growth. The only downside is it needs to be dried with no heat, which can take a while, but that's to be expected with wool. We ended up buying two so we always have one clean. It's expensive, but it's really one sleep sack to rule them all, based on the temperature range and size range, so it's worth it to us.Ver másVer menos

  Improved sleep for baby and more importantly Mummy!

  I have to say that I am a huge fan of the concept of sleeping bags, not just because of SIDS but because they are easy. This product is by far the best I have tried of 5 including Love to Dream, Bonds, the original Sleeping Sac, Ergo Baby, and standard Big W.Pros of sleeping sacs: You can change your baby without disturbing them, pick them up and take them out of the room if you need too. Leave them in it after bath time while you read and they stay warm, no waking up and crying because of the sudden drop in temperature from mummy when you settle them in your arms and need to transfer to the cot.Negative to sleeping sacs, they have all the different TOG rating. We are in Kansas and it can be 74 in the house at 8pm and 65 at 2am.That is why I love this product. I have marked four instead of 5 stars for comfort because the nature of having a 2month to 2 year sac makes it a little loose around the chest and it can bunch up slightly. But don't let that sway you away from this product.The wool makes it heavy, which helps settle baby come sleep time, it breathes keeps her warm and cool and is self wicking which as a new mum nobody tells you how much a baby sweats!The product itself is well made using large zips and decently sized press studs to accommodate for the thickness of the material. It's well thought out and while I haven't used the seatbelt pockets I intend to go in a road trip soon so will update this review accordingly. I do however use these openings to check her nappy without disturbing her.My biggest negative is that it smells when it's wet which is a great warning when baby springs a leak. But after washing the first few times the whole room smelled like wet wool. This however is a minor irritation and you just need to dry in a well ventelated area.The product itself is expensive compared to the competition, I have used 5 different brands of sleeping sacs and the woolino blows them all out of the water. As I mentioned earlier I really like having the chest area a bit tighter to prevent it riding up while baby is sleeping, however it's made to last and the next best sleeping bag I have found by ergo baby you need different TOG ratings and a new size every 3-6 months. So while individually Woolino is more expensive it's less in the long run.You do need two though, now that my baby has discovered her feet I would like to try the legs version so in the evenings she is dressed for he'd and we can put yet straight down without disturbing her if she drifts off.I can't recommend this product enough as a mother of a baby who just does not stop. Even in sleep she waves her legs around and slams them into the cot just for fun. A blanket comes off. A sleeping bag does not!My thanks you to the owner of this product!

  The Only Sleep Sack You’ll Ever Need!! Soft, Durable, and Thoughtfully Designed

  I can confidently say the Woolino All Seasons Sleep Sack is one of the best baby purchases I’ve made. It truly lives up to the hype, especially when it comes to suitability, fit, softness, durability, color options, and zipper quality. 1000000% worth it!The suitability is unmatched. This is genuinely a year-round sleep sack thanks to the merino wool lining, which naturally regulates temperature, keeping baby warm when it’s cold and cool when it’s warm. That means no guessing TOG ratings or constantly switching sleep sacks with the seasons. (which is great because as a FTM, that confuses me!!!)The fit is incredibly well thought out. The universal sizing (2 months to 2 years) is a huge value, and the adjustable underarm snaps make it feel snug and secure even for smaller babies. It fits safely around the upper body while still allowing plenty of room for leg movement, which is exactly what you want.The softness is next level. The merino wool interior is incredibly gentle and breathable, paired with an organic cotton outer that feels smooth and cozy against baby’s skin. It’s one of those products you can tell is high quality the moment you touch it. LOVE!When it comes to durability, this sleep sack is built to last. It holds up beautifully through frequent use and washes (look on their website how to wash since it’s Wool) without losing shape or softness, and the fact that it grows with your baby makes it even more worth it.The color and appearance options are also a big plus!!!! There are so many adorable, modern patterns and neutral tones to choose from, making it easy to match any nursery style while still looking clean and premium. I went for a gender neutral so I can use for my next baby!Finally, the zipper quality is excellent. The two-way zipper is smooth and sturdy, making nighttime diaper changes quick and easy without fully waking your baby. It also has protective features to keep it away from baby’s skin, which is such a thoughtful detail.Overall, this sleep sack checks every box!!!!! Comfortable, practical, long-lasting, and beautifully designed. If you’re debating it, it’s 1000000000% worth the investment. I am in love!Ver másVer menos

  I wish this for every baby!

  Love this sleep sack!If you're anything like me - first time mom over here - I was obsessed with whether baby was too hot or too cold from day one. Overheating or being too cold can be uncomfortable for baby and prevent them from sleeping, and severe overheating has been linked to SIDs. Thus, keeping baby at the perfect temperature - especially as a newborn when they're bodies are still not able to regulate - has been a constant concern of mine that required much thought and effort and trial and error with what temperature to set the thermostat in our house, how many layers to dress in, etc.For my now 7.5 month old, we've been through a number of swaddles and sleep sacks. We live in Los Angeles, so pretty mild weather but still gets chilly in the winter, enough to warrant turning on the heat and obviously, very warm in the summer. We keep the baby's room between 68-72 degrees, which is the recommended range (an indoor thermostat is a must for baby's room! We have this one and we're happy with it: ThermoPro TP55 Digital Hygrometer Indoor Thermometer Humidity Gauge with Jumbo Touchscreen and Backlight Temperature Humidity) In the warmer months we've been dressing baby in a lightweight 100% cotton footLESS pajama or long-sleeve onesie with pants no undershirt, no socks and in the cooler months, footed 100% cotton pajamas, sometimes the slightly thicker organic ones, and no undershirt (please, don't dress baby in polyester, especially not at night, it does not breathe and can cause overheating). The sleep sack comes with a guide as to how to dress for what weather. We basically just followed itThis is a very high quality sleep sack, from the zippers to the snaps, to the soft material and design, the weight is really nice, not too heavy but heavy enough to feel cozy. On a typical spring to summer evening, the temperature in the nursery can range from 72 to 68 or sometimes even 67 degrees farehnheith. The sleep sack keeps baby cool and dry, and warm and cozy. Just perfect. I'm not attributing the fact that baby sleeps really well ENTIRELY to the sleep sack but I do think it has helped. And also has alleviated my concerns and give me peace of mind. Priceless.Ver másVer menos
