Sleep sacks
Sleep sacks in cotton and natural fibers, accurately sized, with no added flame retardants.
Sleep sacks replace loose blankets and remain against the infant for long periods. Synthetic fabrics and flame-retardant treatments add chemistry. Cotton and natural fibers without those additions keep the garment simple while meeting safe-sleep needs.
