Rapha, nice but a bit pricey?

Core Rain Jacket

Even the guy in the shop the other day told me that I'd boil in this, so don't see the point.

When it comes to rain jackets you've got 2 options, something like the Shadow or Gabba jerseys which are breathable but not fully waterproof or a boil in the bag, packable jacket like the Squadra you have. The Core Rain Jacket is the latter, it will pack up small to fit in your pocket and be fully waterproof, but don't expect it to be breathable. It won't do anything different from your Squadra expect maybe have better zips/seams/cut.

This is very new: http://www.goreapparel.co.uk/gore-bike-wear/men/one-gore-tex-active-bike-jacket-with-shakedry/JROFOC.html

But it's receiving very good reviews. I'd be tempted to try that.

Edit: i.e. http://road.cc/content/review/201644-gore-bike-wear-one-active-bike-jacket gives it a 9/10 would buy.

I can say with certainty, the Classic Wind Jacket is useless in the rain. I really like it for commuting in and find it remarkably breathable but it doesn't cut it in the wet.

People talk about the pack jacket being showerproof and it claims to be on the product page.

I'm after a packable jacket for getting caught out in rain/ coming off tops of mountains. I have Gabba for truly wet days, I have Pro Team Jacket for colder not so wet days

If I'm already wearing one of the above, I never bother to take anything else. Saying that, there are no mountains here in the Peaks, at least not like Mont Ditchling and Col de Box.

@clem-fandango Thanks!
