0 of 8 doneHow to pack a grab bag: start with the weight
Our reasonable practice is simple. If you cannot carry the loaded bag comfortably for a good walk, take something out. There is no official weight limit, and a bag that suits one person is too heavy for another.
Test it. Load the bag, put it on, and walk round the block or up and down your stairs. If your shoulders ache or you lean forward, it is too heavy. Bags that feel fine in the hall feel heavier after twenty minutes.
Water is the weight problem. Carry a modest amount, and rely on a collapsible water carrier (Retailer link coming soon) that folds flat until you fill it. Our guide to what goes in a grab bag covers the list, and our evacuation checklist covers when to leave and which documents to take. This article covers the packing.
Use the bag you already own
You do not need a special bag. A school daypack, a gym bag with straps or a small rucksack works. Look for padded straps, a zip that closes fully and a size you will not be tempted to fill. A smaller bag is a good limit on overpacking.
Packing order
- Heavy near the back. Put water, tins and anything dense against your back, so the weight sits close to your body.
- Soft items in the middle. Clothes, socks and a hat cushion the heavy items.
- First-needed on top. A torch, a phone charger, hand wipes and your document pouch should come out without emptying the bag. A head torch (Retailer link coming soon) clipped on top keeps your hands free.
- Outside pockets. Snacks, a small first aid kit, tissues and a card with phone numbers.
- A {{aff:FF-098|compact rain poncho}} within reach. You will want it fast if it rains.
Waterproofing
Rain gets into bags. Line the main compartment with a strong bin bag or a dry bag, and keep small items together in zip bags. A waterproof document pouch (Retailer link coming soon) protects copies of key papers. Pack a foil blanket (Retailer link coming soon) for warmth if you are stuck outside. Follow the maker's instructions on the pack. Foil blankets are very light and take almost no space.
Versions for different people
A child's bag. Keep it very light and let them help pack it. A comfort item, a snack, a book, spare socks and a card with your number is enough. Adults carry the heavy items. Our guide to an emergency plan for kids has more.
An older adult. Weight matters even more. Pack medicines in the original boxes, a list of what they take, glasses, hearing aid batteries and a mobility aid if needed. Ask their GP or pharmacist what is sensible to carry, and do not stockpile beyond what a clinician agrees. Another person can carry water.
A pet. Pack a lead, a few days of their usual food in a tin or a pouch, a bowl, waste bags, a copy of vaccination papers and a collar tag with your name, address and phone number. Our pet emergency kit guide goes through the list.
A budget version
Start with what you own. Use an old bag, a bin bag for a liner, a torch you already have, a few snacks and a printed list of numbers. That is a good first grab bag for next to nothing. Add items from your next shop, and see our budget emergency kit guide for the order to buy things.
Review it twice a year
Be Ready advises checking supplies and dates every six months, so tie the bag to the clocks changing. Swap snacks, check batteries, update papers and medicines, and try the bag on again. Take something out if it has grown heavy.

Questions people ask
How heavy should a grab bag be?
There is no official limit. Our reasonable practice is to carry only what you can lift and walk with comfortably. Load it, put it on and walk around. If your shoulders ache or your posture changes, remove something. Children and older adults need lighter bags.
What do I put at the top of a grab bag?
Put the things you will need first on top: a torch, a charger, hand wipes, a card with phone numbers and a document pouch. Keep heavier things near your back and out of the way, so you do not unpack everything to find a light.
Do I need a special bag?
No. A school daypack, a gym bag or a small rucksack is fine if the straps are comfortable and it closes properly. Line it with a bin bag or dry bag. A smaller bag also stops you from overpacking.
How often should I check my grab bag?
Be Ready advises checking supplies and dates every six months. Pick two dates a year, such as when the clocks change. Replace snacks and batteries, update papers and medicines, and weigh the bag again.
