I have a similar pair for belaying (sport, not winter - I get very cold fingers) - deer skin with a thermal lining:https://www.kinco.com/product/101hkBest combination of warmth and being tactile enough for rope handling I've found. Amazon and ebay sell them. Price has gone up a lot in the past 2 years though - mine cost £15, now £34 from the same seller (though some other, similar versions are cheaper).
Those Freezemaster gloves look good
