Pros: Comfortable is a multitude of temperatures
Helly has taken their superb Mission shell shape and made it a bit more resort versatile by adding Primaloft insulation and their revolutionaryH2Flow temperature control system. Helly bills the H2Flow system as “Warmer. Cooler. Lighter.”. The first element of the system is the innovative use of negative space in the jacket by creating holes that fill with air, these holes trap and control the body heat and add an additional layer of insulation. which helps you stay warm. The second element is allowing the heat to be controlled through strategically placed zipper which allow the heat to be released so you can cool down quickly without getting cold. The third element of H2Flow is the high warmth to weight ratio, by integrating the H2Flow in a jacket like the mission, Helly is able to reduce the weight by 30% compared to traditional insulating systems.
Thats all well and good and looks great on paper, but does it work? Simply, yes. I was able to compare the this and the Mission Shell Jacket back to back in similar testing conditions, both on 0*-15* temps and warmer 20*-35* temps. I was impressed with the light weight of the Mission w/H2fow and it definitely did not feel like I was wearing a bulky insulated jacket in either of the testing conditions. What impressed me was not the cold temps that the Mission was able to keep out but how comfortable it was on the warmer days where a typical insulated jacket usually feels heavy and cumbersome. Mobility was very good with the relaxed fit, articulated elbows and proper pocket placement. I like the ability to zip the Mission shell into the Mission Cargo Pants (review to follow) with the Fusion design to make a pseudo one-piece for the extreme powder days. The well designed powder skirt with two silicon beads snaps away when not in use. The insulated hood is also removable depending on weather conditions you will be skiing in, a very good feature for Tahoe when we get a few straight weeks of bluebird days but the temps fluctuate from bitter cold to 40’s. I really cannot think of any features that have been missed in the Missions design, and this goes for the shell too.
