i have the planet X lobster gloves. They are the only ones i have owned so cannot compare. They are warm, but i still feel the cold through them at minus degree temps.
How weird, Carnac lobster gloves advert has just come up on my Instagram feed from PX.
Bloody google snooping.
PX have some for £19.99 - two finger type.
PX have the Carnac versions at £9.99 + P&P at the moment. I've been using these for the past few years and are the only gloves that stop my fingers from getting too cold.
