Only sleepsack I'll purchase for my kids. In fact, Woolino is included in every baby shower gift I give. From the moment I tried Woolino with my son (now 4), he slept better. It keeps him warm when it's cool, the right temp when it's too warm. The price is higher than others, but both my kids have worn these sleep sacks for EVERY SINGLE nap and bedtime since they were 3 months. They hold up, wash well and resell for 50-75% of original purchase price. Worth every penny.
