S McBeanwrote a review of Mavic Helium Jacket - Men's on April 30, 2015
Familiarity: I've put it through the wringer
This jacket has all the style of the airline under-seat life jacket. It's wrinkly, ugly, and mine is the color of a plastic water cup. But it's there when I need it, does the minimum I need it to do, and it's always appreciated.
There are always trade-offs. If you want a rain coat that will keep you dry in a miserable downpour, it's easy enough to find one that the Gorton's Fisherman would approve, but the catch is that if it stops raining you have to stuff something the size of a rolled-up sleeping bag into your jersey pocket. That's where the Mavic Helium jacket comes in. If you work hard at it, it can be stuffed into a Ziploc bag about the size of a Snickers bar. (Then you have the Ziploc bag for your phone while you wear the coat.) If it really rains on you, you're going to get pretty wet because it is too minimal to be a really effective cruddy-weather jacket. (I got called a "wet rat in Saran Wrap" by a friend). However, I have found that the Helium is the jacket I'm actually willing to take along on a ride where I *might* get rained on, making it unusually useful in a world of bulky rainwear. If you know it's going to rain, wear a crazy submersible 20,000 mm coat. If it might rain, take this.
