What's perishable? For how long?
The only perishables are food and water. Both are US Coast Guard approved, made in the USA, and have a 5-year expiration date.
To make sure you get the maximum lifetime use out of them, we will have the food and water made as close to our shipping date as possible. Why? Because our backers deserve the freshest batch.
What about extreme freezing and heat temperatures?
An exact statement from our partner manufacturer in the US: Both the food rations and water sachets have been tested in temperatures from -30° C to 65° C, and retain their integrity. If such extremes are always present, the shelf life will diminish.
That said, if it's in your car and it's below freezing outside every now and then, they should hold up just fine. If it's an every day freeze and thaw, over an extended period of time, we would recommend swapping them out a bit sooner than the guaranteed 5 years.
Best advice - if consistently in challenging climates, we would just check on the food and water every now and then to ensure all is holding up well.
