Just how much water do you consume ?
Think about using a Camelback
I have. I did not like the feel of it on my back. Maybe just me being an old fart.
RE: Water consumption. The photo I shared was taken on a July 4. It was 95 degrees plus and humid. But what else is new. Photo was 25 miles in on a 50 miler. I had drained the two smaller bottles already and would empty the larger one well before the end of the ride. Fortunately there was a bottle filling station on the return.
Sorry if this is a hijack.
