How to Choose the Right Sleeping Bag (Buying Guide)
When selecting a sleeping bag, consider the temperature rating first. For most campers, a bag rated around 20–30°F is ideal for three-season use. If you plan winter trips, look for 0°F or lower.
The next major choice is insulation type:
- Down insulation: lighter, more compressible, warmer for its weight.
- Synthetic insulation: cheaper, performs better when wet, more durable.
Your camping style matters too.
Backpackers need saved weight; car campers prefer comfort; overlanders often choose versatile all-season bags.
Lastly, pay attention to fit, materials, and packability, especially if space in your vehicle is limited.
