Could someone tell me the size that this packs down to?

I’m keen if it’ll fit into the back of my jersey

It will do mate yes
Cracking bit of kit

Great. I know the best waterproof won’t keep you dry in the worst but if it keeps me warm. I shall order one now

Bit of a thread hijack but how breathable is the jacket?

Pretty breathable. You do feel a bit clammy in it if your sweating for a few hours, but it’s by no means the worst out there.

The big hiking/climbing clothing makers have more breathable offerings albeit a bit more expensive.
