Been a huge windshirt fan for years, so versatile over a t shirt or an extra layer that weighs next to nothing if stuffed in a pocket/pouch. i tend to wear one most days when in "civies", I've got one that's about 20 years old, don't know what it's made of or what make it is, i was under the impression it was para silk?
Of the reviewed lot i have a couple of the houdini's, both at less than half the rrp from fashion websites rather than outdoors ones (they always do better sales
and fashionistas tend to have a short "in vogue" lifespan).
Also have a montane something? and rab cirrus windshield, it's tight but I think I prefer the rab, it's a more comfort (fat lad) fit and has waist pockets, where as the patagonia & montane are more fitted and only have a breast pocket that takes a mobile phone at a push. Not a fan of the montane hood and I think I get more static shocks from it
