This guy seems to be sponsored by Oakley. Now, Oakley makes some good stuff, including some awesome boots I should review some day, and the assault gloves featured in this video (approved by both Batman and Delta Force). And I should note, you get what you pay for in terms of quality. But Oakley stuff is expensive, and most of it isn't designed for combat. His vest and his leg pouch are for adventure seekers. They aren't designed or constructed for hauling military gear or taking the abuse that's associated with combat.
His leg pouch can carry magazines, but they're just tossed into the top pouch. He's going to be fumbling around looking for one when his back is against the wall and zombies are closing in. A dedicated pistol mag pouch will hold the magazines sure and true and he'll be able to lay his hands on one quickly and reliably.
And it looks like he's soaked all his money into the Oakley gear and cheated himself on the giant bowie knife. His SOG tomahawk is a good choice, but that bowie looks like a flea market special. Maybe if he'd spent less money on his video collection, he could've purchased a San Mai steel Kukri from Cold Steel. That's a worthwhile investment.
