The Kryptek Waterproof Pack Cover is a waterproof rucksack cover made from technical fabric with taped seams, designed to protect your pack from heavy rain and adverse weather conditions during hunting, field operations or trekking in demanding environments. Available in three sizes — M (30–50 litres), L (50–70 litres) and XL (70–110 litres) — it fits the majority of tactical and outdoor packs on the market.
The waterproof fabric with taped seams prevents water ingress even during sustained, heavy downpours — unlike simple water-repellent fabrics that eventually saturate. This construction is particularly relevant for those carrying moisture-sensitive equipment in the field — optics, radios, loose ammunition — who cannot afford to stop and shelter their load.
The Kryptek Obskura camouflage is designed for low-light and transitional environments, with a pattern that breaks up the silhouette of the pack both in daylight and in poor visibility conditions. The pack cover is the first visible element of a kit on the move: matching it to the pack or the rest of the kit reduces the overall visual signature without adding meaningful weight to the load.
Key features
- Taped seams eliminate the typical leak points found in untreated sewn covers, ensuring protection even in driving rain.
- Three distinct sizes cover packs from 30 to 110 litres, suiting both tactical day packs and large-volume assault packs.
- Kryptek Obskura camouflage breaks up the pack's silhouette in changing light conditions, completing the kit's camouflage without adding bulk.
- The dedicated waterproof fabric — not a simple surface treatment — maintains its performance after repeated use and washing.
