Review on 🚲 Osprey Seral 7 Lumbar Bike Hydration Pack - Claret Red, Size One by Stephen Cernatescu

I've done a lot of research on hydration bags even with a cheap backpack from Walmart. Although the backpack works, it caused me so much lower back pain that I looked for something else. I read a few pages and settled on this bag. I put it on on my first ride and didn't even realize it was there. You'll have to make small adjustments as you drink more water, but that's okay. This bag has plenty of room for tools and snacks in the side/back pockets. I'm a tall guy and was able to easily adjust it back to my waist.
