Best sleeping bags for DofE 2026: what to buy for Bronze, Silver and Gold

Your sleeping bag is one of the biggest and heaviest things in a DofE rucksack, and one of the most important for a good expedition. The Duke of Edinburgh's Award's own advice is simple: "A 3 season bag should be fine for any Award level." This guide turns that into numbers you can shop with: the warmth rating to look for, the bags DofE recommends, and what each one adds to the weight on your back.

What DofE recommends

• A 3-season bag. DofE's Expedition Kit Guide says it's worth investing in one "to see you through your Bronze, Silver and Gold DofE programmes and beyond". It warns that a two-season bag "in March or October may not keep you warm".
• A mummy shape, which keeps warm air close to your body.
• Synthetic or down. DofE says synthetic is cheaper and keeps more insulation when wet but is "considerably heavier". Down is lighter and more compact but costs more and must be kept dry.
• A compression stuff sack, and always a waterproof bag around your sleeping bag inside your rucksack.
• A proper sleeping mat, not a yoga mat, and a liner if it's colder than expected or you've borrowed a bag.
• Vango's Nitestar, Latitude, Ultralite and Mantis ranges are DofE Recommended Kit. DofE says recommended kit is fit for purpose and good value rather than high end, and that the charity receives a royalty on sales.

What "3-season" means in real temperatures

Season labels aren't standardised, so two "3-season" bags can be very different. A lab-tested comfort rating (ISO 23537 or EN 13537) is a better guide. From Met Office averages, the nights from April to October call for a comfort rating of about -1 °C, or 0 °C with a warm mat. If your expedition is in high summer, about 4 °C is enough. If you feel the cold, go a few degrees lower. Our guide to how to choose a sleeping bag explains where these figures come from.

Keeping your pack under the weight limit

DofE suggests your rucksack and everything in it should weigh no more than 25% of your body weight, and its Kit Guide recommends a rucksack of at least 60 litres for Bronze and often 70 litres for Gold. Your sleeping bag takes a big share of that allowance:

Your share of the group kit, such as the tent and stove, also goes in your rucksack and counts towards the limit, so every gram you save on your sleeping bag leaves more room for food, water and group gear.

Tips for a warm night on expedition

1. Keep it dry. Pack your sleeping bag in a dry bag or a strong bin bag inside your rucksack, as DofE advises.
2. Use a proper mat. DofE says a mat helps "keep the cold from the ground away from your body". Use a closed-cell foam or self-inflating mat made for outdoor use, not a yoga mat.
3. Add a liner if the night is colder than expected. It also keeps the bag clean, which matters if it's borrowed.
4. Sleep in dry clothes and a hat, and keep tomorrow's damp layers out of your sleeping bag.
5. Practise packing your rucksack before the expedition, so you know everything fits.
6. Check with your DofE Leader. Your Expedition Supervisor checks your kit and has the final say.
