A Good Night’s Sleep Makes the Trip
There’s a saying in camping: “There’s no such thing as bad weather, only bad gear.” A poor sleeping bag can turn a wonderful camping trip into a miserable experience. But the right sleeping bag ensures everyone wakes up rested and ready for adventure.
Understanding Temperature Ratings
This is the most important (and most misunderstood) spec on a sleeping bag.
What the Rating Means
The temperature rating indicates the lowest temperature at which the average sleeper will stay warm. For example:
- A 30°F bag should keep you warm down to 30°F
- A 50°F bag is for warm summer nights
Rating Systems
| System | Description |
|---|---|
| EN/ISO Rating | Standardized, most reliable |
| Manufacturer Rating | Often optimistic — subtract 10-15°F |
| Comfort vs. Limit | Comfort = cozy for average sleeper; Limit = survive for cold sleepers |
Real-World Rule
Always choose a bag rated 10-15°F lower than the coldest expected night temperature. If nighttime lows will be 40°F, get a 25-30°F bag.
Types of Sleeping Bags
Mummy Bags
- Pros: Best warmth-to-weight ratio, efficient
- Cons: Narrow fit can feel confining
- Best for: Backpackers, cold weather
Rectangular Bags
- Pros: Roomy, can use as a blanket, double up
- Cons: Heavier, less efficient
- Best for: Car camping, warm weather
Semi-Rectangular (Barrel) Bags
- Pros: Balance of room and warmth
- Cons: Middle ground — not the best at anything
- Best for: Three-season family camping
Kids Sleeping Bags
Children need special consideration:
Size
- Kids bags are shorter (saves weight and warmth)
- Look for bags sized for ages 3-6 or 7-12
- Some grow with your child (extra room in footbox)
Temperature
- Kids sleep colder than adults
- Get a bag rated 10-15°F warmer than you think you need
- Consider a grow-with-me bag for young kids
Fun Factor
- Let kids pick their color/pattern
- Look for bags with built-in pillows or pockets
- Consider sleeping bag liners for extra warmth

Sleeping Bag Care
First Use
- Air it out before first use
- Loft the insulation by shaking it out
- Wash if it has a factory smell
During Trips
- Unroll as soon as you arrive
- Fluff and shake before getting in
- Keep it dry (use a sleeping bag liner in damp conditions)
After Trips
- Hang to dry completely before storing
- Never store compressed — use a large cotton storage sack
- Wash annually with technical cleaner
Essential Accessories
Sleeping Bag Liners
- Adds 10-15°F of warmth
- Keeps the bag clean
- Soft and comfortable against skin
- Easy to wash
Sleeping Pads
- Foam pads: Durable, cheap, bulky
- Self-inflating: Comfortable, medium price
- Air pads: Most comfortable, can leak
- Pro tip: The pad is often more important than the bag for warmth
Pillows
- Inflatable camping pillows (compact)
- Stuff sack with clothes (DIY option)
- Memory foam travel pillows
Winter Camping Considerations
If you camp in cold weather (below 30°F):
- Layer up: Use a bag liner inside your bag
- Hot water bottle: Fill a bottle with hot water and put in your bag
- Wear a hat: You lose most heat through your head
- Don’t breathe in the bag: Moisture from breath reduces insulation
- Insulate from the ground: A good pad is essential in cold weather
