A quality sleeping bag is the foundation of comfortable camping. Here’s how to choose wisely.

Down vs Synthetic Fill

Down Fill

Synthetic Fill

Pros: Affordable, performs when wet, easier care, hypoallergenic Cons: Heavier, bulkier, less durable long-term

Best Choice

• Backpacking: Down (weight matters)
• Car camping: Synthetic (comfort, budget)
• Wet climates: Synthetic (reliability)
• Cold winter: Down (superior insulation)
