Hydration jersey (not a pack!) for gravel racing: Castelli Unlimited Pro

The Castelli Unlimited Pro Jersey fits a 1.5L hydration pack in a mesh sleeve on the back, letting you ditch the hydration pack but keep the hydration. I took this into the wind tunnel with Silca, onto the trails and roads with some friends, and I'll be racing in it at Unbound Gravel this year. And yes - I am happy to be supported by Castelli. :-) I do not take money for any of my bike reviews, wheel reviews, tire reviews, etc - and I am able to do so because of the sponsorship of Castelli and my other supporters, listed below.
