I’ve not tried silk liners before but I can see why you’d prefer a brushed lining if they provide the same warmth.
I got the hot hands based on recommendations and they’ve always kept me warm enough on wet, cold rides to the extent where hands have come out a bit clammy (which is where a brushed lining would help) which is massively better than freezing!
I’ll have to try the PolyPro in a few years when these are worn out.
Probably worth clarifying that a below 0 ride is pretty unusual in South Wales so if it’s properly cold, my combo may not be enough.
