Waterproof and windproof over-jacket

[delsol]

Summers coming, I want to relegate the heavy gear to the cupboard for a while.

I like to wear just a leather jacket but I know it's not going to be enough when I inevitably get caught out in rain with a long ways still to go.

Ideally I want something without a fixed hood (small roll collar hood would be acceptable) so my helmet covers the collar.

The more weatherproof the better, I don't want condensation puddling cheap polypropylene that will saturate me with condensation, I've done that and I would rather spend more to avoid it.

Equally important is I want it to be ultra compact, like fits in your pocket, size of an orange ideally.

Precious few shops around here to see gear or try on for size.

Berghaus gore-tex paclite jacket is just too bulky, Haglofs LIM Proof almost meets the criteria but has fixed hood ( https://www.haglofs.com/en-US/products/clothing/fabrics/proof/men/l_i_m_proof_jacket_en-us.aspx ) but I'm sure that there must be other options available, I'm not a snob about labels.

Any recommendations please.
