Trusted: Proudly made in the USA with GOTS-certified 100% organic cotton fabric which has been mom-tested and fully approved for its exceptional softness, breathability and durability. This makes it perfect to serve as sleeping attire for your little bundle of joy throughout their critical physical development. The cotton fabric permits your child's body to respire efficiently, preventing overheating and minimizing the risk of their developing rashes or eczema outbreaks. 

Practical: This sleeper bag comes with a one-way reversed zipper to guarantee your child cannot unzip it accidentally. By opening from the bottom to the top, it facilitates convenient and hassle-free access when it's time to change your baby's diaper. At the same time, it's premium velour fabric, like all our fabrics, has been washed with hot water before it was cut. This ensures the likelihood of shrinkage is effectively eliminated. This sleeper bag is designed to accommodate the growth of your baby, offering them more room without encumbering their movement. Size S (3-6 mos.) features fold back mitts to keep little hands warm and protect little faces from scratches. 

True to Size: No need to size up since we designed the sleeper bag with room for growth. Click on the size chart to find the height and weight range for each size. Your child's height is the most important measurement for a sleeper bag. Be sure to consult the far right-hand column of the size chart where we list the actual length of the bag in each size. If your child's height is at the top end of the size range for their age then choose the next size up. 

Preshrunk: For best results, turn garment inside-out and machine wash warm, line or tumble dry. Non-chlorine beach only. Do not use fabric softeners or dyer sheets.

Cozy and Comfortable

The sleep sack I bought for my grandson, in size 3T, looked huge when it first arrived, but it has proved to be a cozy & comfortable fit for him. The generous fit makes it more like a blanket covering his legs. I never worry that he will be cold while napping at Grandma’s house.

So Warm and Comfortable

My daughter is just about two and a half. I need something that would help keep her warm during cold winter nights, and this is working so well! I am very glad I purchased it.

Perfect for toddler

My son is almost 2 but doesn't use a blanket. This keeps him warm all night long and is long enough!
