Choosing the Right Self Inflating Sleeping Mats
Pick by the temperature you'll actually camp in - a 3-season bag works from spring to autumn UK use; 4-season is for winter camping or high altitude. Manufacturer comfort temperatures are tested under standard conditions and tend to assume an insulating mat under the bag.
Bag Shapes
Mummy bags hug the body for max warmth and minimum weight - the choice for backpacking. Rectangular bags are roomier and unzip flat for use as a duvet - better for car camping and cold sleepers.
Insulation Type
Synthetic fill is cheaper, dries fast and keeps insulating when damp - the right pick for UK campsites. Down is warmer for the weight but useless wet.
Frequently Asked Questions
What temperature rating do I need for UK camping?
Most UK 3-season camping needs a comfort rating of around +5°C to 0°C. Drop to -5°C or lower for any winter camping, or if you sleep cold.
Are these sleeping bags waterproof?
Sleeping bags aren't waterproof - they shed light moisture but won't survive a soaked tent. Always pitch with a footprint and use a dry bag if you're packing on the move.
Can I machine wash my sleeping bag?
Synthetic bags can be washed on a delicate cycle in a large drum. Down bags need specialist down-wash detergent and a long tumble dry with tennis balls. Always check the bag's care label first.
Mummy or rectangular - which is better?
Mummy for backpacking and cold weather (warmer per gram). Rectangular for car-camping comfort and warm-weather use. Some hybrid 'tapered rectangular' designs split the difference.
