sleep sacks
Cotton · No microfleeceEvery product here tells you exactly what it is made of — that is the price of admission.
A sleep sack is pajamas plus blanket in one, worn all night every night. These are cotton through and through — the label says so. The “microfleece” ones are polyester; warm, sure, but so is cotton, without the plastic.
