Sleeping equipment determines whether you recover overnight or start the next day exhausted. Temperature rating, insulation type and mat warmth (R-value) must be matched to the conditions you actually sleep in.
What to consider
- Lowest overnight temperature you expect to sleep in
- Insulation type — down vs synthetic for wet conditions and pack size
- Your sleeping style — side, back, cold-sleeper or warm-sleeper
- Mat R-value for insulation from the ground
- Pack size and weight for walk-in trips
Key specifications
- Temperature rating — comfort, limit and extreme
- Insulation fill and fill power (for down)
- Mat R-value for ground insulation
- Shape — mummy, semi-rectangular or rectangular
- Packed size and trail weight
Who this is suitable for
- Three-season backpackers balancing warmth and weight
- Winter campers needing high-loft bags and high R-value mats
- Wet-climate campers who benefit from synthetic insulation
- Comfort-focused car campers who can carry rectangular bags
Things to compare
- Comfort rating against the coldest nights you expect
- Mat R-value — often more important than the bag for ground cold
- Down vs synthetic for the moisture and pack-size you accept
- Shape and roominess versus warmth and weight
- Packed size against your pack capacity
