You need to add a hernia repair kit, if you're lugging all that stuff around everyday.
01 extra pack of undergarments from Sam's Club (I'm not revealing any more details)
We appreciate that.
That should cover things for the foreseeable future.
You can never have too many spares.
All my joking aside ... on the serious side though - since this is for a "grid down" situation (i.e., "no power") - don't you want to add some type of portable power? A few batteries? A solar charger maybe?
