Gavin L. wrote a review of Outdoor Research Helium II Jacket - Men's on August 3, 2012
I'm not given to posting reviews but I just took my first run with the OR Helium II. I am seriously impressed. So light and so quiet for a waterproof that I had to check to make sure it hadn't leaked (and it hadn't). Wicked the moisture away so well that I didn't feel hot and bothered one bit - and it's August in New Jersey! It's beautifully spartan but has a zippered pocket for all that I need on the trail, tight cuff seals, ample room and perfect drawcord adjustments. And, soooo small in its stuffsack. Pretty near design perfection. I'm always leery of corporate mottos but 'designed by adventure' rings true for this company. This jacket is clearly designed by folks that walk the walk (or run the run. in this case).
