Ver precio en Amazon →Reseña completa
The PurComfy Supersoft was actually a recommendation from our pediatrician's office — one of the nurses mentioned it during a well visit, and I'm glad she did. The bamboo viscose fabric is noticeably softer than the cotton sacks we started with. Owen didn't fuss when we put it on, which is the ultimate baby product test.
The 1.0 TOG rating is what makes this the everyday workhorse. Our nursery sits around 69-71°F year-round (because apparently I now care about room temperature to the degree), and the PurComfy handles that range perfectly. In winter with the heat on, it works. In summer with the AC running, it works. We don't have to think about switching sacks with the seasons, which is one fewer decision in a life that's already drowning in baby-related decisions.
The 2-way bottom zipper is excellent for nighttime diaper changes — unzip from the bottom, change the diaper, zip back up, baby barely stirs. The sizing runs true, and we've moved through the 0-6M and 6-18M sizes without issues. At its price point, we bought three so we always have one clean, one in the wash, and one in the diaper bag. That's not something you casually do with a $50 sleep sack.
