Up for sale is an incredibly rare, highly collectible vintage rucksack from the legendary heritage outfitter Willis & Geiger. This bag is crafted from their proprietary, ultra-dense Bush Poplin cotton—a tightly woven, long-staple Egyptian yarn engineered to be naturally windproof, water-resistant, and mosquito-proof without synthetic coatings.
This specific model is a true piece of cinematic and outdoor history, highly sought after by archival fashion enthusiasts and movie prop collectors alike (notably featured as the iconic "Lucky Pack" in The Lost World: Jurassic Park).
