desertcart.com: Mosebears Sleep Sack Baby Winter Wearable Blanket with 2-Way Zipper,2.5 TOG Cotton Sleep Sack Unisex (White Animal, 18-24 Months) : Baby

Review: Lovely, warm, soft - LOVE this sleep sack. So soft and so warm. It's like a wearable comforter. My son who runs cold at night, slept well in this all last winter. I'm looking for a larger size now.
Review: The BEST Sleepsack by a Hardcore Critic! - I’m typically pretty hard on baby products as far as critiques. Especially things I’ve purchased on desertcart because you can’t see or feel them in person. HOWEVER! This sleep sack is simply amazing! We live in mid-Michigan where the temps have gotten down to -10 at night. But even on a typical winter night where it is in the 20’s or teens, it gets down to 65° in our house. She has slept SO soundly with this sleep sack because she’s stayed nice and warm. The sleep sack itself is BUTTERY SOFT ORGANIC COTTON!!! I’m fairly certain the inner lining is cotton as well. It’s definitely filled with fluffy, plush, comfy polyester. The zippers are good quality and strong, never get stuck or caught. Overall, FIVE stars!! (My sister just had a baby a few days ago and I even bought one for my new nephew so he can wear it this coming fall/winter) Super soft, super warm and thick, great quality! If you live where it’s cold, don’t hesitate. Look no further! This is an amazing sleep sack!

### ⭐⭐⭐⭐⭐ Baby loves it!
*by S***E on December 28, 2024*

The Baby loves it! Easy to take on and off. Once in the sleep sac it's lights out and it is clearly very warm and comfortable! It was true to size since my child is between 16 and 24 pounds, the medium worked best for us. This is a much more resonable price than the Halo and other brands. Be sure to put the zipper cover over the top zipper. It would be good to have a button securing that top cover zipper like most footies have, but that is more of a suggestion that an actual problem. We have had it for a couple weeks and it is worth it for a safe and snug sleep. I clean it with Dreft and white vinegar on Normal cycle with delicate setting in the dryer since it recommends low heat. I do have to dry it 3 times on that setting or the bottom stays wet. That could be more about my dryer than the sleep sack. Yesterday I dried it on medium heat to make things a little faster and it did lose softness so stay at the low dryer setting. I will be getting a second one! Update: The second one is just as good as the first! Unfortunately, my baby grew and they are now uncomfortable in the size which is a bummer since I just bought the second one. I'm going to buy a bigger one.
