We own three of these so we can keep them in rotation. They're so soft and cozy, love knowing that baby is comfortable in any temperature.

This sleep suit is worth the price tag! I appreciate the natural fibers and that this is the only sleep suit I will need to buy for my daughter. It saves me money in the end! I also appreciate the room thermometer that came with the sleep suit, it helps me know the temperature of her room and how to dress her accordingly.

We love our Woolino sleep sacks so much. Each of my kids has had a woolino from 4 months to 2 years. The quality is unmatched.
