Make naptime and bedtime extra comfy with our supersoft sleeping sack made of 100% organic cotton. The natural hued crinkle gauze material with sweet microstripes adds a charming touch to the wearable blanket, and it's lined with oh-so-soft organic cotton jersey to keep little ones snug and cozy.

This sleeping sack has a TOG rating of 2.5. TOG stands for "Thermal Overall Grade," which is a measurement of insulation and warmth. It's recommended that TOG ratings for baby sleeping sacks stay between 0 and 4—the higher the rating, the warmer it will keep your baby. Sleepwear with a 2.5 rating is on the warmer side, so this one's best for room temperatures of 61º–68ºF.
