Two new, unopened 500ml soft flasks. These were included with the Salomon hydration vest backpack ACTIVE SKIN 8 SET, which I purchased new this month on Amazon. I am selling them because I only use the vest. Only the two flasks are included; there is no box or instruction manual. Although they are new and unopened, please refrain from purchasing if you are overly concerned about condition. Non-smoking household, with pets. Photos 4 and 5 are screenshots from the time of purchase. Please note that the vest is not included. They will be shipped in simple packaging to reduce shipping costs.
