I have used Buffalo Pertex/ fibre pile mitts for some years with every success. They are flexible and give reasonable manipulation ability. they are lightweight and showerproof warm when wet, and they dry while you watch. Buffalo are made in Sheffield and AFAIK don't have retail outlets so are well geared up for mail order and exchanges etc. There is a website.
Watch the sizing though. AFAIK Buffalo only make one range of mitts. So the Small fits a smallish child, the Medium fits a smallish female hand and the Large fits my small man's hand. They make sizes up to about XXXXL One good feature is that one can wear one size on top of the next smaller. So I wear Large in normal bad weather and put Extra Large in top in the worst weather.
I have also found that if I wear really warm clothing on the rest of me, my hands don't seem to get cold at all even without gloves, unless there is a very strong wind or freezing rain. So many jumpers and a thick woolly hat makes for warm hands – which is handy for manipulating things.
I have not had much success with Thinsulite. This seems to make thin dress gloves, OK in reasonable conditions around town or as inner gloves, but little use in real cold, wet or wind.
