Whether you intend to spend the night out in the wilderness or end up doing so in an emergency, a good quality bivvy bag or emergency shelter will help to protect you from the elements. Bivi Bags give you a much more authentic and honest outdoor experience, they are smaller and cheaper than tents and of course you only need a very small patch of flat ground. We have bivis and shelters from Rab, Black Diamond Lifesystems and Outdoor Research, with a range to suit every situation and budget be it a simple Survival Zone shelter or an Alpine Bivi Bag. If you haven't tried bivvying then we'd highly recommend it but be sure to do your research and keep a close check on the weather!
