Choosing a sleeping bag for your camping trip is all about balancing comfort, warmth, and cost. Consider the time of year and opt for a bag that's rated for the temperatures you'll encounter: a 1°C (33.8°F) rating or higher for summer, and a below freezing rating for winter. The insulation type is also key, with down-filled bags being light, warm and easy to pack, though a little on the pricey side, while synthetic insulation is more affordable, quick-drying and effective even when damp. The shape of the bag can also affect comfort and warmth, with mummy-shaped bags being warmer but less roomy, and rectangular bags offering more space to move. If you're hiking, go for a lightweight option, but if you're driving to your campsite, weight won't be an issue. Lastly, look out for handy features like hoods, draft collars, and pockets, and ensure the bag is the right size for a comfortable night's sleep.
