I've spent the majority of today researching rain gear for my commute. I've narrowed it down to three jackets:
Gore Oxygen 2.0
Showers Pass Elite Pro
Rapha Hardshell Jacket
What these jackets have in common is the price point. Not cheap to stay dry. The Rapha is particularly pricey at almost $500. Maybe I'll just poke some holes in a garbage bag and call it good.
