Hi all, this is actually my first post here I need to upgrade the standard inner gloves from kubi and I've narrowed it down to the kubi alpaca gloves and the fourth element xerotherm gloves. The main difference between them seems to be the material they're made from - xerotherm is a synthetic polyester blend whereas alpaca wool is a natural fibre. They're both good at wicking. They're about the same price. It looks like the xerotherm gloves are bulkier but it's hard to tell from just the pictures. I have no idea which is better at retaining heat. I do get cold hands - I dived the whole summer with 9mm wetsuit gloves. But I also like to use my fingers Right now I'm layering the basic kubi gloves with a cheap pair of soft gloves I used to wear while running. It's not particularly warm and not very dexterous either. Can anyone tell me how xerotherm and alpaca differ? Thanks.
