500ml blue hydration bottle with a screw cap. It came with a Salomon bag I purchased. I haven't used it because I don't do mountain climbing. There's a protective seal on the mouthpiece. If purchased on weekends or holidays, it will be shipped on the first business day after. It will be folded up small for shipping. - Brand: SALOMON - Color: Blue - Capacity: 500ml - Cap type: Screw cap Thank you for looking.
