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

I use this when the weather gets too hot for my Raptor backpack. So I can take everything I need and enough water with me for my trips. Four stars is because the zipper that closes on the water bladder tends to come loose when you use the tube. It never opens up enough to lose anything, but it's annoying. Also, the magnet could be a little stronger. Some falls and jumps have loosened the hose. It doesn't cause any problems, but again just an annoyance. I love the backpack and would recommend it to anyone looking for an alternative to hydration packs.
