Another Arundel fan here.

Mine have pink accents on them.

I love them. It's funny... the roadie guys are always the ones in the club who zoom in on my pink accent carbon cages lol.

They can slide and adjust down just as posted. I ride a small triangle 49cm Orbea Onix Dama.

Rock solid hold. Never a problem.

Even survived my posted crash a while back--not one problem. AND still held the freakin water bottles dead in place with the bici doing a 360 cart-wheel on top of me in the road on impact.

Now, man... THAT is what I call performance lol.

Oh... on the whole wearing a CamelBak for water thing as a roadie...

They do make a roadie style vest that is like an undershirt. I had it ordered. Then my order got messed up & I canceled yadda yadda. BUT, I think that's another source of more H2O provided you can deal with weight directly on your back on the roadie. I personally have some back issues and can not.

On the mtb I'm more upright, not in one position as long, or as low, like the road. It's just diff.

I think George H. wore a vest like this at the Tour one year. FWIW.

I could see this next to bod vest being a really nice thing for winter cyclists (assume would not freeze like external bottles can). Plus, they do make a CB insulated straw too. I have winter CBs for xc skiing that have this straw. You can just get the straw sep and switch it up. More options to consider in the big water picture. On a thread drift note lol.
