A bit big in the waist

  • Familiarity: I've used it once or twice and have initial impressions

I am 165 5'11". I wear a large in the Phantom, but I got the medium in this one. The jacket fit nicely in my shoulders, but the waist is too big. I switched it out for a medium, the shoulders and arm length were acceptable, but the waist was still a bit big. So I tried a small, it was way to tight in my shoulders, and you could see my veins in my forearms through the jacket...but the waist was the perfect size.

Anyway, I paid $120 after discounts for the jacket, and I couldn't pass up the deal, so I just got the medium and used the sinchers around the waist. It doesn't fit as nicely as I would like, but still looks and feels fine.

How does this compare against Thermoball or Nano Puff jackets?

Responded on

I have both, and both are good in 30 degrees and higher. I started with Thermostatic with I was heavier then 40lbs less later, I bought Thermoball for better fit. When you pack it, Thermostatic is smaller than Thermoball. My thermoball is a bit bad in stitching, not sure why. Both are light and I pretty much use it almost every day on mild weather. I use it as my mid layer for colder than 30 or sometimes i use other mid weight body tight layer than either one of them will work just fine. You just make sure you have the right fit. My thermoball is in M after losing so much weight, and now a bit tight since I'm into body building and my chest are bigger and wider. I must cut down on the chest workout ... but anyway'll be fine with both.

Comfortable, warm, snug, no chest pocket

  • Familiarity: I've put it through the wringer
  • Fit: Runs small

This lightweight, packable jacket is warm and comfortable when sized properly. I've worn this on hikes in shoulder season, underneath a light shell while climbing big antennas for BASE jumping, and as a casual jacket around town. I'm impressed with the construction and insulation. It holds out the wind and chill well, and even stands up OK in a light mist/drizzle.

I've used this jacket enough that I've had to wash it several times. I run it through the washing machine on normal mode with other clothing, and I air dry it. It has always puffed right back up to its original loft and warmth.

I found the fit a wee bit tight in the armpits. If you're an avid climber or gym rat, and have well-developed lats, you may find the same. I'm 5' 9" and 165 pounds, and I found the medium to be perfect everywhere but in my armpits.

I would have loved to see a chest pocket on this jacket, but in all other respects it has served my purposes well and has been rugged.

Favorite Jacket I own

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I had some Mammut jackets that were similar. This one won.
Its packability, warmth and over all comfort are a necessity when on the trail. I love it. After climbing Pikes Peak in it, I am confident that its one of the best you can get for the money, and could probably compete with something twice its price.

Sizing runs great.
Love the rusty color of it.
Definitely wicks moisture if you have a little drizzle or snow coming your way.

Over all, Ideal jacket.

Best jacket ever

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I love this jacket! I'm 5' 10" at 182lbs lean athletic build and the medium fits like a glove. I could have went with a large, but the medium serves as my base layer. I have many shell's, middle weight's, and base layers from arcteryx to marmot and including mountain hardware. I've been continuously grabbing my thermostatic. Best jacket ever for moderate activity at 40-50 degrees (walking, moving around town). Performing Severe activity you can wear this jacket in the 30-40's (heavy pack on incline). This jacket is so light, it feels like there is a pillow of air wrapped around you. Fantastic!!!! Plus excellent compression and size for stow.

I would like to have this jacket, do not know the dimensions of the video in this is how much? M or L?

Responded on

wutao. Your best bet to choose the right size is to click either the size chart above or let us know your dimensions and we'll give you the best advice. I am 5'9" 150 and a medium fits best although I am on the small size of the medium scale. I have no idea what size jacket is being used in the video but our samples are medium and that is probably what is being used. Hope this info helps!

Thank you very much, ah, I actively measuring a bit, and I did not think your body is so close, I now understand, M must for me.

Sweet. now my wife wants one

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

The jacket was great. I tok it backpacking in sub 30% with howling wind and it was nice and toasty. I am 6'1" and 170. I bought the Medium for a nice close mid layer fit. it was great.
