Huge protection-Small package
- Familiarity: I've used it several times
I was looking for a lightweight Gore-Tex jacket that would provide the ultimate protection I might need if the shit hit the fan at altitude. I took this one to the new Opas Taylor Hut between Aspen & Crested Butte for its maiden voyage. Was I impressed! It was blowing hard at 12,100' so I skied with just a thin wool layer and the Transonic. The bit of stretch and windproofness made it the perfect amount of protection while breathable enough to ski uphill with a pack. It fit over my down sweater when I was standing around at the top of the pass trying to figure out where the elusive hut might be. (several people have gotten lost and benighted trying to find this newest addition to the Braun Hut System)
It's one chest pocket is spacious but not ideal for town use where you might want more storage. Pockets add weight and bulk however so this is perfect for light/fast pursuits.
For backcountry use, I can't think of a lighter, more breathable outer layer. I'm a huge fan of Gore's Active Shell fabric for its balance of wind protection and warmth while eliminating the sauna effect.
