Here's what others have to say...


Extremely light weight and weather proof

  • Gender:Male
  • Familiarity:I've used it several times
  • Fit:True to size

I've used this jacket for fly fishing, hiking, and sea fishing in SE Alaska. It keeps the moisture out and breathes extremely well. I love the trim fit and how easily it packs downs and weighs next to nothing. It doesn't have hand pockets, but I knew this going into the purchase. This will be my go-to jacket for ice climbing this winter.

My only complaint with the jacket is that the wrists are not adjustable. Yes, they do have elastic in them but, the Hulk himself would struggle filling out the wrists of the jacket. This did cause rain to come in while fishing on the river. If you will be wearing a glove with any sort of gauntlet over or under the sleeve, then this shouldn't be a problem.

  • 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.
