Main Types of Sleeping Bags
By User Group
(1) Infant Sleeping Bags
- Swaddle Bags: Mimic the womb's embrace, ideal for 0-6 months to reduce startle reflex and enhance security.
- Arms-Up Bags: Allow natural "hands-up" positioning for less restriction.
- Legged Bags: Designed for toddlers (1+ years), offering freedom of movement while preventing kicking off covers.
- One-Piece Bags: Suitable for 6-12 months, with more legroom for easy diaper changes.
(2) Adult Outdoor Sleeping Bags
- Mummy Bags: Body-hugging for maximum warmth, ideal for cold climates.
- Rectangular Bags: Can be fully unzipped as a quilt, better for warm weather or home use.
By Insulation Material
- Cotton: Affordable, retains warmth when damp but heavier.
- Down: Lightweight and ultra-warm, but expensive and loses insulation when wet.
- Fleece: Best for summer or as a liner for extra warmth.
Key Features
Temperature Regulation
- Body-hugging design minimizes heat loss. Premium models (e.g., LittleTiny) use Outlast® thermoregulating fibers for adaptive warmth.
- Infant bags often rate warmth in TOG (Thermal Overall Grade):
- 0.5 TOG (summer)
- 2.5 TOG (winter).
Safety
- Eliminates risks of traditional blankets covering a baby’s face, reducing SIDS (Sudden Infant Death Syndrome).
- Neck and arm openings should be 11-13cm wide to prevent choking or drafts.
Convenience
- Two-way zippers and detachable sleeves simplify dressing/diaper changes.
- Legged designs support active toddlers.
Buying Guide
Size
- For infants, choose a bag ~10cm longer than height to avoid slipping inside.
Material
- Opt for 100% cotton or bamboo cotton (breathable, antibacterial); avoid synthetic irritants.
Seasonal Adaptability
- Lightweight for spring/autumn, heavily insulated for winter.
Brand Recommendations
- Infants: LoulouLOLLIPOP (bamboo cotton), LittleTiny (temperature-regulating tech).
- Outdoor: Down bags (alpine camping), synthetic bags (humid conditions).
