Millet Trilogy Pro GTX Jacket - Men's

Named after the three peaks it was designed to summit.

Don't even think about heading up the Eiger, Matterhorn, or Grandes Jorasses without wearing the Millet Men's Trilogy Pro GTX Jacket. This lightweight jacket utilizes a Gore-Tex Pro shell for guaranteed waterproof protection against any condition you might come across up there, and it also remains crazy breathable to keep you as comfortable as possible while you trudge your way to the top. An Alpine fit accommodates a harness without bulking up your outfit, and Flex Comfort construction includes pivot sleeves for unrestricted mobility and precise execution with every move.

The Trilogy Pro GTX also features large zippered vents to let out a significant amount of steam during the toughest sections of your climb, and the zippers are water-resistant. The zippers at the large hand pockets are also water-resistant, and you can access the pockets with your pack and harness still on. The hood slides over your helmet with ease, and the protective visor prevents the hood from blocking your vision while you belay your buddy.

My favorite jacket of all time, I will buy another Millet gore tex coat should anything happen to mine. That being said, I don't think I'll ever need to buy another one because this thing is BOMB PROOF!



Mine is a different model...

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

The one pictured is a different model but in the same line of jackets, and I bought in on and it's the nicest coat I've ever owned. Super comfortable and could stop any storm you threw at it. It works well for skiing and winter climbing, an all around work horse with comfort and amazing material. Gore tex is simply the best IMO.

Take it from a serious skier and a rather accomplished one, it's well worth the extra coin to invest in a jacket of this caliber on

Talk to a gear rep and they'll say the same thing folks. Happy winter!

I'm wondering if this jacket would be long enough for me?
6'6", 225lbs, long torso.
If not, any suggestions on shells (of similar quality & purpose) that would work for a long & lanky fella like me would be much appreciated.


Millet is not quoting the length on their site, but it doesn't really matter because you can tell that the sleeves are longer than the jacket. You will want something that is longer than the sleeves, since you are so tall.

For solid mountaineering jacket, you want to look at the Arcteryx Theta SVX, which is 31.75 in length and the Arcteryx Theta AR, which is just 1/2 an inch shorter.

More questions? Just call or email me, directly.

Thanks Emily, I appreciate the advice.

Happy New Year!


Awesome JKT

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

I totally love this JKT. Super fun colors, goes great with a harness.
I have log about 15+ days of ice climbing with it!!


Interior pocket, with the only fabric worth wearing in weather.



Solid zippers, zipper hoods, pulls, etc. All good details.



Ample cuff with good tailoring so that they shink without getting clumpy.


Proshell with great details

Millet struck a nice balance between comfortable fit and technical performance in this jacket. Like any jacket worth it's salt, it's made with GoreTex Proshell, and Millet decked it out with nice details, like durable zippers, zipper hoods, a removable powder skirt, a helmet-compatible hood and cuffs that will fit over any glove system.

I've used this shell in the snow on Mt Hood, with sideways weather and flying ice, and also on early pre-dawn mornings crabbing along the oregon coast. In a large, the jacket fits my 5'11" 160lb frame on the bigger side, which will accomodate a puffy jacket underneath for the colder days. If you want to wear it over just a thin midlayer, a medium would be a better fit.

One thing that I love about the jacket is the number of pockets. While some jackets become bulky nonsense as soon as manufacturers add pockets, the Millet has two enormous hand pocket, a chest pocket, and an internal device pocket which all disappear when you're not using them. They're easy to access and can hold you gloves, food, sunscreen, or whatever else you want to keep nearby.

The dark blue is a nice royal navy color with just enough Euro touch on the zipper colors. Hood adjustment is simple, with pull tabs outside the hood (are you listening arcteryx?). Pit-zips are standard issue-- nice and long, and as easy as any to manipulate. All zippers have solid zipper pulls.

This jacket is kitted out for serious weather. Throw it over an insulating layer, slide some big gloves under the ample cuffs, and go get some pow!

How large is the hood on this? I've had 2 Millet's in the past where the hood is too small for a medium sized smith vantage ski helmet (which isn't that large). Would this hood fit a helmet of this size?

Best Answer

I don't have experience with this helmet, but it fits my petzl meteor 2 easily.

This jacket was updated to have a ski-helmet compatible hood.

Thank you! Ended up picking up the L and the helmet works. Appreciate the help.

The Gore Active version of the Trilogy Pro. Different Gore fabric, but same overall build/shape/paneling/fit. Great Piece.

Bomber and great price for Gore Pro

This jacket is extremely well-designed for alpine climbing and backcountry skiing. Features such as the "pivot sleeve" (it's an added panel in the under-arm) keep the jacket taught on the waist when reaching up to swing an ice axe. Actual drains are at the bottom of the huge skin pockets, so melted snow doesn't build up and wet out the internal pockets. Removable powder skirt, ski/ice helmet compatible hood that has light foam in the brim, a wire, and height and depth adjustment for the perfect fit. Two-way center zip and the main pockets are set high enough to use when wearing a harness or pack. This is one of the pieces that is vetted and used by the Chamonix Alpine Guides. Last, the Price is stellar for European-made Gore Tex Pro. Look at similar styles from Arc or Patagooch and you pay at least $100 more for an Asian-made jacket.

I've heard Millet runs small. How should we size the GTX Pro jacket relative to, say, Arc'teryx?

I size up from other brands, so I buy XL in Millet when I would be L in most everything else that is US, or Canadian. I'm 6"2, 175, and the XL size fits great.
