Insulate PEX Bundle

[Gilles Guezille]

How can I insulate a PEX bundle, actually 2 bundles, going to 2 manifolds?
There isn't enough room between them or slack between hangers to use foam sleeves.

Why is there a manifold there?

I am feeding a whole bathroom with dual sink, toilet, and tub: that's 4 cold and 3 hot inlets.
