2.5 TOG Sleep SackThe Ultimate Layer of Warmth and Safety

When Does Your Baby Need This "Wearable Comforter"?

A 2.5 TOG rating is high, specifically designed for a winter sleep sack. It's the only solution you need to replace the dangerous practice of piling on blankets when the room temperature drops below 69°F (20°C).

Core Benefits:

  • Maintains a stable warmth all night, so you don't have to worry about your baby kicking off blankets.
  • Allows you to maintain a bare crib, strictly adhering to the most important safe sleep guidelines.

How to Dress Your Baby Under a 2.5 TOG Sleep Sack

Dressing your baby correctly will help improve their sleep by ensuring they don't overheat. Here is our detailed guide:

  • 64-68°F (18-20°C): A long-sleeved pajama set is sufficient.
  • 61-64°F (16-18°C): A long-sleeved bodysuit underneath a pajama set.

Important: Never put a hat on your baby for indoor sleep. Always check their neck to ensure they are not sweating.

Warmth That Breathes

Many assume a winter sleep sack must be thick and stuffy. However, the material makes all the difference. SwaddleAn's 2.5 TOG sleep sacks are made from multiple layers of organic cotton, which effectively trap warmth in natural air pockets while still allowing your baby's skin to "breathe," preventing clamminess.

Peace of Mind with Safe Design

Beyond warmth, every 2.5 TOG sleep sack is designed for safety, featuring a two-way zipper for easy diaper changes, a chin guard for protection, and a roomy bottom for healthy hip development.
