Babies love being cozy (really, who doesn’t?). And while adults usually only bust out the sleeping bags for camping trips, for babies, they’re actually a safer alternative to blankets, which can provide extra hazards for a squirming babe. Unfortunately, infant sleeping bags rarely combine the warmth, size and comfort your little one needs for every season and every growth spurt… until now.

With the 365 Sleepybag, you get two interchangeable bags — a cool summer bag and a mild autumn/spring bag. When you layer them, your baby is prepped for winter. The bag is economic with its sizing, too. It comes in only two sizes: 3-24 months and 2-4 years. This way you’re spared the expense of buying a new bag every time your baby has a growth spurt, which can seem like every week.

And don’t fret a second about your baby’s delicate skin. The bag is made with 100% Certified Organic cotton, with the zipper safely sewn on the outside. Inside, your little one is coated in ultimate softness. They take extra care to make sure no chemicals are used in the bag, so that babies with sensitive skin or eczema can sleep without irritation.

To make this expert prototype a reality, the company is raising money on Kickstarter. If you make a $120 pledge by November 14, you can be one of the first to snag your own 365 Sleepybag.
