Review on 🎒 Osprey Seral Lumbar Hydration Pack: The Ultimate 2020 Model for Active Outdoor Adventures by John Espindola

The backpack is bigger than it looks, but that's not a problem. It has two design flaws, one of which can be significant. I bought it for road running and it works great for that purpose. The magnet holding the handset is not very strong. It holds up for road running, but I doubt it's suitable for trail running or mountain biking. The part with the magnet likes to slide down the tube when drinking. It's not a big deal with running, but it's a much bigger problem with cycling. To fix this I made a stop at Sugro. A rubber band would probably work too, but I had some Sugru. The big downside is that the hose doesn't sit low enough on the bladder so I couldn't pump out all of the water. The photo shows how much water I couldn't get through the pipe. Depending on the situation, this can be a big or a small problem.
