As of my knowledge cutoff in September 2021, Gregory Mountain Products, the company behind Gregory Packs, was owned by Samsonite. Samsonite, a global travel luggage and accessories leader, acquired Gregory Mountain Products in 2014. By combining Samsonite's resources and distribution channels with Gregory's expertise in outdoor backpacks, the acquisition aimed to strengthen the position of both brands in the outdoor gear market. However, please note that ownership structures can change over time, and it's advisable to verify the current ownership status of Gregory Packs, as my information might not be up to date.
