I have another very light sinylon jacket, 100g or 3.9oz, which is
water/wind proof, and packs very small, easily stored in the jersey
pocket when it's "imploded" into its little pouch. Made by Nalini.
But it's not good for cold weather, there's too much condensation.

I think that the mesh liner is designed to soak the condensation from
the outer shell, which would otherwise be soaked by the clothing.
I'm planning an experiment this weekend with/without the mesh liner,
and I'll let you know of the result.

In summer I plan a big come-back to Tibetan plateau.
