    Game changer! I bought this to replace my old water bladder and it fits way better in my pack. The magnetic valve is super convenient.

  2. Alan Cook (verified owner) –

    Super easy to refill and clean, which is great after long hikes. Definitely feels like the best 2 liter hydration reservoir for hiking I’ve used so far.

  3. Douglas Olson (verified owner) –

    I read some Gregory hydration reservoir reviews 2025 before buying—glad I did. It’s light, sturdy, and doesn’t leak. Highly recommend!
