In reply to Dr U Idh:
An alternative might be PowerShield, if you're after a more sturdy shell. PowerShield uses a perforated membrane (Malden's Air Control Technology version of their Windbloc membrane), which allows more air to pass; the 'Goldilocks' amount, if you like...
I was fortunate to pick up one of the Patagonia Core Skin jackets from R&R, which I am getting to like, and has a very effective DWR.
I have two Microtherm jackets, one which wets out pretty quickly (and always has), and a later one which is much better; practically waterproof. It may be that ME have changed the DWR.
