Best overall — ideal warmth rating and bamboo softness for everyday use
Buttery-soft bamboo viscose with a perfect 1.0 TOG rating — the Goldilocks sleep sack for year-round room temps.
Full Review
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.
