Nine Mountain House pouches: add hot water to the pouch, wait, eat from it, so there's no pan to wash when water is short. The food is closer to a proper meal than most buckets. But it's about 1,706 kcal a day for three days, and the dearest day of food on this page.

Our review
Mountain House's Just in Case 3-day kit is nine just-add-water pouches for one person, about 1,706 calories a day by the maker's count. It is the kind of food you would actually want to eat after a storm, packed small, with a 30-year taste guarantee. This review covers what is inside, what it needs and where it falls short.
What is in the box
Mountain House describes the kit as breakfast, lunch and dinner for one person for 72 hours: 18 servings in nine pouches. Breakfasts are two pouches of Granola with Milk & Blueberries and one of Biscuits & Gravy. The rest are entrées: two pouches each of Chicken Fried Rice, Chicken & Dumplings and Beef Stroganoff with Noodles. The Chicken Fried Rice is certified gluten-free by GFCO; the other meals contain allergens including milk and wheat, so check the labels if anyone in the house has an allergy.
The box measures about 12.75 by 9.25 by 7 inches and weighs 3.6 lb, so it slides onto a closet shelf or into the bottom of a go-bag. Mountain House notes that packaging may change.
How the meals work
Each pouch is its own cooking pot and bowl. Mountain House's instructions are to open it, take out the oxygen absorber, pour in the stated amount of boiling water, stir and seal, then eat in under 10 minutes. There is nothing to wash afterward, which matters when the tap is off or under a boil-water notice.
The whole kit needs 12 cups of water to rehydrate, just under a gallon. That is on top of drinking water: Ready.gov asks for one gallon per person per day for several days. You also need a way to boil it, and Ready.gov is clear that camp stoves and charcoal grills are for outdoor use only. Our guide to cooking without power covers the safe options.
Calories and shelf life
The maker gives about 1,706 calories a day. Adding up the nutrition panels on its page gives a similar figure, roughly 5,060 calories across the 18 servings. That is a little under the 2,000 a day often used as an adult reference, so a larger adult or someone working hard clearing storm damage may want snacks alongside it.
The 30-year figure is a taste guarantee from the date of manufacture, and Mountain House says it depends on storage: dry, sanitary conditions, no long spells of extreme temperature, and no punctured or dented packaging. If a stored meal disappoints, the company says it will replace it.
How it compares with the other picks
On our emergency food comparison, this is the small, premium option. The ReadyWise 72-Hour Kit gives more calories for the money, and the big buckets such as the Emergency Essentials 1-Month Kit cost far less per day but lean on rice, oats and beans. Mountain House sits at the other end: fewer calories per box, but full entrées that need no pan.
It suits a single adult who wants a ready-made three days on the shelf, a car or office kit, or a household that wants a few easy meals on top of a pantry stockpile. Our emergency food storage guide explains how to build the rest.
The verdict, and who should skip it
A tidy, good-tasting three days of food for one person, with clear instructions and very little mess. It is not the cheapest way to store calories, and it is not quite 2,000 calories a day.
Skip it if you are feeding a family on a budget, if you have no safe outdoor way to boil water, or if you want food that can be eaten straight from the package with no preparation at all.

Who shouldn't buy this
Don't buy it if budget is the priority: the ReadyWise 72-Hour Kit gives more calories for half the price.

How many people does the Mountain House 3-day kit feed?
One person for 72 hours, according to Mountain House. The 18 servings work out to about six a day for a single adult, so a family of four would need four kits for the same three days.
Can you eat Mountain House meals without hot water?
Yes, in a pinch. Mountain House's FAQ says cold water works if you give the meal about twice as long to rehydrate. Boiling water is the standard method and gives a hot meal, so an outdoor stove is still worth having.
How much water does the kit need?
Mountain House says 12 cups in total, about three quarters of a gallon, to rehydrate everything. Store that separately from your drinking water, which Ready.gov puts at a gallon per person per day.
Does the 30-year shelf life mean it is safe for 30 years?
Mountain House frames it as a taste guarantee for 30 years from manufacture, conditional on proper storage. Keep the box somewhere dry, away from heat swings, and discard any pouch that is punctured or swollen.
