Mt. Rainier is the tallest Mountain in Washington State and when you are bivying at the base of Interglaicer, in order to make your moonlit summit bid, warmth and protection from the weather is priority 1. Those who know and understand this pick the Mountain Hardwear Compressor PL Jacket for Men as their synthetic insulation piece because it has a great warmthtoweight ratio and continues to insulate even when wet.
Extremely warm and very low pack volume
I have used this jacket extensively from cold weather sailboat racing to winter sports. It's great under a shell. It feels like you're wearing a thin shirt but with the warmth of a down jacket. Get one.
Great Jacket
Light, simple, and warm. I had this jacket on during my summit of Mount Shasta a couple weeks ago. It kept me toasty and I barely knew it was on!
Comfortable wear
Very warm and very comfortable to wear. Although the jacket is thin, it keeps the cold out very well.
