Outdoor equipment maker Vango and Virgin Mobile have teamed up to bring weary festival-goers the R&R Sleeping bag.

The Rest & Recharge Sleeping bag functions not only as your traditional pocket of warmth on cold and muddy British summer nights, but also as a handy recharging dock for your mobile phone.

A built-in battery hooks up to your mobile once it’s been placed in a secret storage pouch to make sure it never runs out of juice.

The limited edition bags can be ordered from


for £50. You’ll be asked which type of mobile phone you have to make sure that your sleeping bag comes with the right charger.
