Designed and developed by U.S. veterans, the Viktos Perimeter 40L Backpack is the ultimate 72-hour go bag. This 40-liter backpack is built-tough with Mil-Spec materials and can accommodate EDC supplies, pistol and rifle mags, a 15-inch laptop, and a 3 L hydration bladder. DWR weather-resistant coating keeps gear dry when the bottom drops out, while internal padding prevents bumps, scuffs, and abrasion. Padded shoulder straps, an adjustable sternum strap, and an aluminum reinforced internal frame sheet evenly distribute load to reduce stress on pressure points. This EDC tactical backpack is available in multiple colors and backed by a 1-year workmanship and materials guarantee.
