Warm but NOT breathable

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: X-Large

Pre-soaked trash-bag level breathability. I only used it once: it was completely useless. Took it on a run at a cool 45 degrees, normal humidity. Just a tech T underneath. I'm not a huge sweat-producer; when I over-layer, I get uncomfortable but rarely sweat significantly. The initial warmth felt right for the temperature and the heat zoned down was cool. That's where the good ended.
This was the least breathable article of clothing I have ever worn, including trash-bag ponchos. I literally had pools of sweat collecting in my elbows and running down the arms, out the sleeves, and down my pinky fingers after about 15 minutes of moderate running. My hands were dripping - from a jacket. I don't know how this made it to production.

Front Toward Enemy

  • Familiarity: I've put it through the wringer

Excellent wind resistance and baffled down sections for an efficient warm that doesn't overheat. The backside however, is essentially a glorified cheese cloth that allows wind to cut right through.
