You're up before the sun, you're the first to volunteer leading technical pitches, and you push your limits in the harshest conditions—face it, you need a jacket that can perform in nasty weather as well as you can. When you pull on the Millet Men's Trilogy Synthesis Down Hooded Jacket, you'll have the protection to face the most inhospitable environments. The revolutionary Synthesis seamless construction and hydrophobic K Dry Down provides unparalleled thermal capacity while maintaining breathability; the double-weave structure creates seamless baffle design to prevent heat loss, increase tear resistance, and boost windproof properties. When temperatures drop, you can pull up the fully adjustable, helmet-compatible hood and cinch the collar, hem, and cuffs to seal out the cold. The Trilogy can be worn as an insulation or stand-alone piece thanks to the DWR-treated shell.

Evaluation of the Millet Jacket Synthesis (down fill, size US medium)
The jacket fit very well for me at 5’7” and 150 lbs, and comfortable with a medium weight insulation layer underneath. The color and look of the jacket is sharp looking with the dark blue/purple. Structurally sound is what comes to mind with my inspection of the fabrication, including the all important zipper that zips up from the bottom for the belay access. The jacket also performs nicely when tucked into the harness and the pocket access in available just above the waist line. I noticed that the feather baffles are ‘welded’ instead of stitched and immediately upon wearing the jacket i could feel the warmth difference, as i was previously wearing another with stitched seems of the approximate weight. I Guide Rock Climbing in the windy desert of the Mojave South west California where the speeds have reached about 90mph (not kidding) in the spring, and this is where the hood, the collar, and the low cut back are very nice!! With the collar zipped up all the way there is plenty of space to move yet the warmth coverage reaches just above my chin and comfortable. The base of the jacket is nicely cut in front to meet my body at the bend and in the back the material drops down just enough to cover my ‘tail end’. When I reach up the jacket sleeves remain at my wrists and the base stays low to cover below the pant-line maintaining that important overlap. When wearing this jacket I feel very well taken care of in the winter winds of Joshua tree, with plenty of mobility and comfort.

I give this jacket 5 stars.

I have left the patagonia nano puff and simply used this instead. It packs up smaller, has reasonable water repellency, is warmer, and has a solid helmet compatible hood. I've been using this jacket since early December, and I could not be more impressed with it. Millet products in general and cut for slimmer europeans frames, not corn fed American ones, so if you're inbetween sizes, you might go larger. Mine is a large, and it is snug, but it fits well enough. This is a sweater weight or light belay jacket, not a full belay jacket, so keep that in mind. I am on the 2 puffy jacket program, including this and the heavier Millet down parka. I don't leave home without both. Sleeves are a great length, it has real zippers, not junky ones, and the pockets are correctly placed for climbing use. I've been using it daily guiding all over the northeast in cold, and damp environments.

Millet is not (yet) a major player in the US adventure sports apparel market, but their alpine pedigree runs deep in Europe and their attention to detail shows in the Trilogy Synthesis Down Hoodie. Based on my experiences using it for several weeks this winter guiding ice and backcountry skiing, I’d characterize it as a high quality climbing sweater, ideal for belay duty on warmer ice days (where drippy ice and wet snow place the jacket’s excellent water repellency and treated down at a premium), colder alpine rock conditions, and even shady and/or windy Red Rocks routes in the shoulder seasons. It’s also a great piece to actually climb in on frigid days, with a trim and athletic cut, thoughtfully located pockets (2 vertical chest as well as hand pockets) that don’t interfere with your harness, and a hood that fits well over even larger foam-style helmets. The functional hood draw string also yields a reasonable fit without a helmet. For standing around at the belay while your gripped partner sorts things out on desperately cold missions, you’ll want more, but if you’re after a highly compressible, lightweight piece for belay duty in warmer conditions, or to actually climb in when the mercury plummets, the Trilogy should be on your short list.
Features I’ve appreciated
• Treated 700 fill power down, making the jacket quite warm for its weight (significantly more so than a Patagonia Micro-Puff, in my opinion).
• Trim cut, making it reasonable to actually climb in. If you want a roomier fit, consider bumping up a size. At 5’11” and 165lbs, a medium fits reasonably well, but only barely, and is perhaps a bit narrow across the shoulders. The sleeve length is on the money, however, and adequate even for swinging ice tools overhead.
• Well-designed, helmet compatible hood
• Seamless baffles. No doubt this contributes significantly to the jacket’s warmth and windproof qualities.
• A bit wider cut in the shoulders might be helpful for some
• A hang loop for drying the jacket. How can a piece of this caliber, made for real climbing use, and to get wet, not have a hang loop?
• A more functional stuff sack. While the included sack is adequate and includes a strap for clipping the stuffed jacket to a harness, I’ll still be swapping it out for a small, ultralight compression sack, as I do for almost all my down and synthetic insulation pieces. Down’s compressibility is among its advantages, and a compression sack leverages this characteristic.
• Warmer weather ice climbing belay duty
• Cold shoulder season or alpine rock
• Climbing in on frigid ice days
Ob balance, I give it 4 stars, though if there was a touch more width in the shoulders, I'd bump up to 5. This piece has become a staple in my pack.
