Unanswered Question

I find it hard to believe that the center back length on this jacket is 19". Needs to be re-measured or this must be for short bodied people.

Light, breathable and waterproof.

I love the style and fit of this jacket. It was super comfortable and just looks really nice on. I got a few compliments while wearing actually! The fabric and technology of this jacket are similar to other rain shells in this same category, but I felt like it was more breathable than other rain shells. I never felt hot while wearing it and the weather was variable. I never felt like I had to take the jacket off and then put it back on, I was able to wear it in all different temperatures.

I love the fit of Mountain Hardwear products! They're stylish but insanely functional. This jacket was great for a run in the park with my pup. I saw some rain clouds coming in so I decided to bring this sweet piece before we left. About half way through the run it started drizzling. What I found was most impressive was that when we got home, I was completely dry. My sweat from the run had completely vented through the VaporDry laminate during the light rain. I thought that was pretty impressive breathability! It also has underarm zippered vents, just in case it's an extra muggy day. The adjustable hood lets you ensure that the rain isn't dripping into your face while you're getting poured on. Overall, I was stoked on this jacket, and it's so light that it's not a problem at all to throw in a day pack to make sure that you have the extra coverage in case the elements decide to throw you a curveball.
