Woolino babies with sensitive skin love our sleep bags. They’re hypoallergenic, so it won’t irritate their skin. Not only is it incredibly soft and breathable, but because it is composed of the same protein that makes up the outer protective layer of our skin, it works in total harmony with our skin’s own protection mechanisms. It also inhibits bacteria, so minimizes other allergenic problems. Pictured here is our 4 Season Merino Wool Baby SleepBag, size 2 Months - 2 Years, in Earth Stripe.
