Maybe I missed it in the copy, but these products are on the same (UK) website. Normally I'd be a bit grumpy thinking this article was advertising, but they have quite a few things I've never seen before and I placed an order. Then there was a link in the order confirmation email to the owner, with their dog, saying thanks - nice touch. Happy Winterval!
I think everyone I know in our part of Scotland uses snowsport base layers in the coldest depths of winter. Bike base layers aren't up to the coldest days. It's almost like the bike brands think "nah, it's really not that cold" form their offices in the South!
