Thank you for viewing. This is the high-performance hydration pack "Hydraulics 3L Reservoir" from Osprey. It's perfect for staying hydrated during outdoor activities such as hiking, trail running, and cycling. It has been used only a few times and has been stored carefully, so it is generally in good condition. However, for hygiene reasons, the bite valve (mouthpiece) will be removed before shipping. We would appreciate it if you could purchase this if you are able to provide your own new bite valve. Product Condition & Usage Number of uses: 3 times Contents used: Only water was used. Storage environment: After use, it was washed and stored in a dark place at home for several years. Hygiene: Washed again before listing.
