The Magic of Merino

Because of merino wool's unique ability to regulate body temperature, it helps keep your baby warm when it's cold and cool when it's hot. That temperature regulation means that your child will sleep comfortably throughout the night, year-round – and that means a better night’s sleep for you too.

Better and Longer Sleep

A study done by the University of Sydney has found that a better night's sleep is achieved when sleeping in wool. Merino wool is the perfect fiber to have next to your child's sensitive skin. It regulates temperature, manages moisture, is easy to care for, soft, and durable. It is naturally perfect.

Beautiful and really comfortable. It’s large but I am hoping that it will last a couple of years. It’s really well made and keeps her warm.

I’ve been using this sleeping sack for about a month, and unfortunately, I am very disappointed with the quality. First, the fabric around the zipper started to wear out and tear. Additionally, the stitching isn’t very neat, and some areas look unfinished. The material feels too thin for the winter here – it’s more suitable for summer use. After washing it a few times, I noticed pilling on the fabric, which is concerning for a product at this price. Overall, I don’t think this item is worth the cost. I expected much better quality, especially given the high price.

When I ordered this, I sized up to the 18 month size since I had a drawer full of 18 month fleece pajamas. I wanted this to fit once my baby outgrew those. This was still too big when she outgrew her fleece pajamas so I ended up having to buy more fleece to get us through until this fit. My baby does seem to sleep much better with this. I just wish I had purchased the actual sleepsack with snaps under the arms that would have lasted until 4 years. The arm holes on this are huge! Also, since the cuffs on the foot openings are so loose, baby’s feet always end up inside the sack. It is like she is walking with a sleep sack. I have tried rolling up the cuffs, but the only thing that works it putting socks on. We don’t usually keep socks on her in the house since she has more traction without socks. One other note, I wish the dressing guide would specify if the long sleeve sleepwear should be cotton, wool, or fleece. I don’t think cotton long sleeve pajamas are warm enough for the colder nights even with this sleep sack.

Editing 3wks after using:My 22 months old daughter has been wearing it during 68F with long sleeves, long pants to 78F with only the sleeping sack with feet. So far so good. The temperature at place I'm living (Bay Area) varies during day and night, so I'm glad she's not too hot when it's 78F and not too cold when the temperature drops to 72F late night. This is August, not sure if this sack will still work in September temperature. Looking forward to test it all year round to see if this sleeping sack really covers all seasons.--------------------------I read the reviews and it seems very nice so I made the purchase but it was thinner than I expected. Also my shipment didn’t come with a Room thermometer so I’m not sure how to dress her properly. She woke up having cold hands when temperature was 72F and she had one long sleeve and one long pants on. Not sure if I’m doing right, would like to have the guidelines on how to dress my child at least. Since the thermometer was missing, I’m not sure how likely we are able to keep our child comfortable, we will try one more by adding/removing more layers on her

I love this wearable blanket! My daughter has been sleeping so well since I started using this.A little big but it works great as a blanket scrunching up around her belly to make her feel cozy.

寝相が悪い娘の寝冷え防止にぴったりです！股部分がつながっているため、はいでしまう心配がありません。生地はとても肌触りが良いうえに通年使えるようになっているとのことで、今後も長く使えるのが嬉しいです。睡眠時に使用するものなのでファスナーガードがついているのも安心しました！色も柄も豊富にあり、包装も綺麗でかわいいので、おしゃれなプレゼントにも最適だなと思いました。

入荷を心待ちにして購入しました。一歳7ヶ月で身長80センチですが、18-36のサイズを購入。届いたその日に着せましたが、サイズがまだ大きくダブダブしてるので着たまま歩いたりは出来ませんでした。いつも布団をかけずに寝てしまってるのでこちらの商品は魅力的でしたが、我が家の娘は寝返りをゴロゴロするので、サイズが大きいからか寝返りしにくかったようで夜泣きが増えました(^^;使用して3日目くらいに風邪をひいたのもあって、それからは使ってませんがサイズ的にも来年再来年も使えそうなので買っといてよかったです。
