Giro (used to) do a mesh base layer with pockets in, which you could wear under a loose t-shirt
Had a look but no more.. going to take a punt on a morvelo base layer - seems like the best approach. Could also be real handy for wearing under my waterproof shell that has no pockets.

Also @andyfallsoff the Gravel jerseys look significantly looser than the regular ones, basically just MTB jerseys with Road styling
