Can I reuse an emergency survival bag after I've used it once?

It depends on the condition. If your polythene emergency bivi bag is still intact, you can clean it, dry it, and use it again. But if it's been torn or looks worn out, replace it—they're cheap enough that it's not worth the risk.

What's the difference between a survival bag and an emergency bivi bag?

A survival bag is basically a thin orange plastic bag that's lightweight and pocket-sized, while an emergency bivi is more robust and usually made from better materials. The bivi offers better protection and is reusable, but it's bulkier and lives in your rucksack rather than your pocket.

Do I really need to carry emergency shelter for a summer walk?

Yes. Most UK summer hill walkers carry at least a survival bag or emergency bivi because they're light enough you won't notice them, and they're there if something goes wrong. Carrying basic emergency shelter is just part of going into the hills, like carrying a map.
