Different Types of Sleep Sacks

Sleep sacks are wearable blankets that help keep babies safe and warm while they sleep. They come in a variety of styles, materials, and thicknesses to suit different needs. Here’s a breakdown of the different types of sleep sacks:

By Arm Position

  • Swaddle: These sacks have wings that wrap around the baby’s body and secure with velcro or snaps, keeping their arms snug.
    Swaddles are ideal for newborns, as they can help to startle reflexes and promote better sleep.

  • Transitional: As babies get older, they start to want to move their arms around more. Transitional sacks have wings that can be unfastened, allowing them to have one or both arms out.

  • Wearable Blanket: These sacks don’t have any closures around the arms, allowing for complete freedom of movement. They’re ideal for older babies and toddlers who no longer need to be swaddled.

By Material

  • Cotton: Cotton is a breathable and affordable option that’s great for year-round use.
  • Muslin: Muslin is a lightweight, open-weave fabric that’s perfect for hot weather.
  • Fleece: Fleece is a warm and cozy option for colder weather.
  • Wool: Wool is a naturally breathable and temperature-regulating fabric that can be a good choice for all seasons.

By TOG Rating

TOG (Thermal Overall Grade) is a unit of measurement that indicates the warmth of a sleep sack. A lower TOG rating is lighter and cooler, while a higher TOG rating is warmer. Here’s a general guide to TOG ratings:

  • 0.5 TOG: Ideal for hot weather or room temperatures above 75°F (24°C)
  • 1.0 TOG: A good all-season option for room temperatures between 68°F – 75°F (20°C – 24°C)
  • 2.0 TOG: Suitable for cooler weather or room temperatures below 68°F (20°C)
