The Kryptek Waterproof Pack Cover is a waterproof rucksack cover designed to protect your kit during operations in heavy rain or wet terrain. Available in three sizes to fit rucksacks from 30 to 110 litres, it suits a wide range of configurations: from an assault pack on a short mission to a full logistical load.
The waterproof fabric with taped seams eliminates the infiltration points found on simple nylon covers. This makes a real difference not so much in light drizzle — where almost any cover holds up — but during prolonged halts in driving rain or direct contact with wet vegetation: situations where the non-breathable material keeps moisture out, though internal condensation remains a trade-off worth considering if the pack is worn for extended periods during intense activity.
Kryptek Altitude camouflage is developed for high-altitude environments, with cool tones on grey and white: effective in rocky, snow-covered or alpine terrain, less suited to dense vegetation or low-altitude settings. Size M fits rucksacks from 30 to 50 litres, L from 50 to 70 litres and XL from 70 to 110 litres: choosing the correct size is essential, as an oversized cover will not sit flush against the pack and will shift in the wind or through branches.
