Why we picked it
One sleep sack from two months to two years, which replaces the parade of sized polyester ones. Merino lining regulates temperature so well that Woolino publishes no togs: the same bag works in winter and July. Wool also self-cleans between washes by shedding odor. The zipper and snaps are ordinary hardware. Parents hand these down still working.
What it’s made of
