No jacket is going to be truly breathable, waterproof, and windproof. I have a closet full of many brands to prove it :)
The only thing I have not tried is eVent, and am not willing to buy another expensive jacket with the same results.
So far, my Essence has worked better than anything I have used, including a very expensive PacLite. So here are some thoughts…
– I get cold easy. So others might sweat in the conditions that are just perfect for me.
– The pit ventilation doesn't seem to do anything. On jackets with pit zips, I can feel some difference but not enough to regulate my torso.
– Works pretty good as a wind jacket, but not as well as my Montbell UL wind jacket. Of course it is cooler/breathes better than the wind jacket.
– I don't need or want hand pockets. I like the chest pocket for my small camera. I also usually hike with a Rail Riders Eco-Mesh shirt, and am in the habit having a chest pocket for my camera.
– When using the Essence as a wind jacket and wearing a T shirt, my arms feel clammy against the material. Feels much better with a long sleeve shirt.
– I don't like the elastic sleeves. Seems it would be cooler with sleeves that are loose around the wrist. I often wear it with the sleeves pushed up around my forearms.
– I am 5'11" and thin. My size should be a medium, but I like size L in jackets. I can wear my Montbell Ex UL Down Jacket under the Essence without compressing the down.
– The bottom of the jacket just covers my buttocks, when not wearing a pack. I have never paid attention to how low it goes with a pack on.
– I like the full length zipper vs an anorak. Gives me more ventilation options. But I have never liked anoraks at all… just a personal thing. Also the zipper is opposite of a convential jacket… like a woman's jacket here in the U.S. That is a minor incovenience. Sometimes in windy weather, I will zip it almost all the way down, and my pack straps and belt keep it from flapping around and it helps to keep me cool.
– I use it a combo rain/wind jacket.
– Keep in mind that when it rains here in the west, it is usually cool or cold, unlike other parts of the country in summer.
– It is light at 6.7 oz.
– I bought mine last year on clearance somewhere. I think it was under $100, but I had to settle for a caution orange looking color.
So it is not perfect by any means, but it works better than anything I have used before. I really prefer a poncho, but they suck in wind. I have used the Essence a lot, and often wear it around town. This winter I wore it every morning when walking my dog. I probably need to wash it, as it is starting to get stinky.
