20 years of innovation has lead to the hyperlight MP+ Membrane system. Our two layer membrane system on the HyperLight MP+ Waterproof Jacket allows for a 20K waterproof Rating and 25K breathability in an 85 gram package.
Stay informed even in the worst conditions with the left hand watch window giving you quick access to your data at all times.
"The Raidlight HyperLight MP+ Waterproof Jacket is an ideal jacket to pack for longer runs or fastpacking adventures where you want protection against the elements while keeping weight to a minimum."
"The fabric feels great and has above average breathability for a waterproof layer – what you’d expect from a jacket designed for moving fast and working hard. As a runner, I can appreciate the minimalist lack of features and weight-saving (i.e., not very roomy) cut."

I knew it would be light from the description, but not until it arrived did I realize how light. It's like wearing nothing and it adds nothing noticeable to your pack weight. Despite the lightweight design, the construction is solid. Ran 100+ miles over almost 2 days in the San Juans with multiple rounds of pretty gnarly thunderstorms. Stayed dry the whole time. It paired perfectly with the Winter Trail top to keep me warm overnight at elevation.
I am super stoked on this jacket for an ultralight race oriented layer. I've had it through a few storms and it has worked great. The only part of me that got wet was from water coming through the hood around my chin. I really haven't been able to find another jacket with at this weight that is as protective or as breathable.
