I had 2 pairs of unger gloves, they don't last long and they stink

If I forgot to take them out of my Trailer the next day my hands would freeze just putting them on,
for an emergency one day I bought a £5 thermal pair from Tescos, I still have them and they are doing well after a month, but the best pair I have is a pair of waterproof firemans gloves, as used aboard ships, leave them in the trailer over night and put them on in the morning and there warm as toast to put on, a bit bulky but who cares as long as my little Mitts stay warm.
