The Survival features the deep internal slant pockets of the Mocker, plus a pair of detachable side-saddle cargo pockets (each with its own closure flap and belt loops.) Basically each cargo pocket can be pulled off and used like a belt pack. Wading across a river and don’t want to get your stuff wet? Pull off the cargo pockets, stuff the rest of the Utilikilt inside and toss it across to shore. Pockets stuffed full as you get to the airport? Pull off the pockets, drop them on the x-ray conveyor belt, and stride on through the metal detector. Wear the Survival for awhile and you’ll be shocked at just how useful these removable pockets really are. The Survival’s maximum capacity is 20 Bottles of the survival beverage of your choice. That’s six in the front slant pockets, ten in the cargo pockets and four in the back. With the Survival around your waist, you’ll never go thirsty.
