Opinions on Sealskinz please.

Hi all, Hoping for some informed opinions on Sealskinz gear please. Specifically the gloves and hats. Would be looking for winter in the UK wear, so cold (-5 to +5), but usually damp cold. They'd ideally be waterproof or at least water resistant. Would be for prolonged outdoor use, usually 8-10 hours walking outside. Thanks in advance.
