The 3 essential items that every adventurer must pack.

1 ZIP-TOP BAGS

You’ll need these to waterproof your gear. “They could save your life,” Grylls says. “You know, people go out with a cellphone, put it on top of the rocks; then it rains, and the phone’s dead.” Throw your wallet in there too.

2 EXTRA SOCKS AND GLOVES

Socks get wet. Gloves are dropped. “Somebody loses a glove in a cold environment,” Grylls says, “and they can die because they’ll suffer a frostbitten hand and can’t use the hand. I’ve had a lot more riding on a spare pair of gloves than you might imagine.”

3 TARP

Rain or shine, “the priority is always protection from the weather. So if you’re in the desert, you need something for shade.”
