Our sleep sacks come in two weights: 
  • Lightweight (Under .5 TOG): Designed for room temps 71*F++
  • Midweight (Under 1.0 TOG): Designed for room temps 68-74*F

Layer your sleep sack to the climate. We recommend you select breathable fibers (like cotton or bamboo), and if the temp is on the colder side, layer footie PJs with a onesie under your sleep sack.

NOTE
.
These are guidelines—always assess your child's PJ and wearable blanket combo to make sure they are not overheating. A key sign of overheating is sweating, with a damp nape of the neck. As a general rule, it's better for your baby to be cool than to be hot. And note—it's normal for a baby's hands and feet to be cool to the touch.
