Sure, you could save some money by building your own safety kit from scratch. But miniaturization makes this pack so small and light that you’ll never hesitate to throw it in a daypack. You get a reliable thumb-wheel firestarter, tinder, signal mirror, a 120-decibel Fox 40 whistle, fishing essentials, and more (see website for complete list).
And unlike many competitors, this kit includes a legit knife, a CRKT flat-blade that fits nicely in the hand. It all stows in a 5.5x4.5x1.5-inch waterproof pouch. But toss in a compass; the included mini is too small. $70; 5.7 oz.; adventuremedicalkits.com
