ak-snowrote a review of Mountain Hardwear Compressor Insulated Jacket - Men's on January 4, 2012
Bought this jacket a couple of years ago. are you kiddin' me. I was skeptical at first about shelling out the cash... but, this jacket does it all. super light weight and packable, yet keeps you warm in all conditions. I wear this alone in the summer, fall, and as a base layer in the winter. even wet, it keeps me warm.
the only downside is that it will rip and wear through quickly. this is an acceptable sacrifice you must make for the weight. a little nylon patch and you are back in business.
