Let’s do the math! I searched Amazon; there are probably cheaper places for all these things. (SemiotixCorp LLC does not use referrer links, and passes the savings on to you.)
“Multitool” amounting to a small Swiss Army knife plus pliers: $3.99
Waterproof matches, unspecified quantity: $2.30
First Aid manual: free, from a million online sources
“micro first aid pouch:” $4.47
Nalgene water bottle (small): $1.89
“water particle filter,” which appears to mean a wire strainer to filter out macroscopic debris: $1.69
water purification tablets: matching the brand, $8.49, but the same thing can be had for $3.95 and in much higher quantity
crankable radio that will charge other devices: $9.95
whistle: $1.47
“disposable toilet bag:” $1.50, plus it comes with a free clip-on leash dispenser!
So for $31.21 you could get all these things (some of them in much greater quantities). Probably less, if you were more aggressive about searching out Amazon deals than I was. Of course, most of these are common household items that you probably already have in abundance anyway. So yeah.
