Mountain House: sizes and calories

Mountain House sells its multi-day kits in flat cardboard cases rather than buckets. The 15-day case is 25 by 10 by 15.75 inches; the 30-day bundle is two of those side by side. Pages give calories per day (about 1,706 to 1,732) instead of a total, so the totals here are that daily figure times the labeled days.

Flat cases suit under-bed gaps poorly

At 15.75 inches tall, a Mountain House case will not lie upright under most bed frames. The planner keeps cases upright, so under-bed checks come back as too big. Laying a case on its side is a choice for you and the maker's packing instructions, not something this site assumes.

Notes on each figure

• 15-Day Emergency Food Supply Kit: No independent listing with the case size was found on Nov 5. Total calories are not printed; the planner multiplies 1,732 by 15 days. Shelf life wording on the page: 30-year taste guarantee.
• 30-Day Emergency Food Supply Kit: Ships as two boxes of 15 days each. The 20 x 25 x 15.75 in figure is the bundle; each box alone matches the 15-day kit size. Shelf life wording on the page: 30-year taste guarantee.
• 14 Day Emergency Food Supply: Calories per day match a second listing. The maker page gives no case size. One retailer lists 19.75 x 12.3 x 15.3 in, which we have not confirmed, so the planner does not use a size for this kit. Shelf life wording on the page: not stated on product text.
• Just in Case 3 Day Emergency Food Supply: Case size not published on the product page. Shelf life wording on the page: not stated on product text.
