Mountain Hardwear Dynotherm Hooded Down Jacket - Men's

Dynobirds of a feather.

It's bigger than a bread box, light as a bouquet of feathers, and it might be distant cousins with the Sinosauropteryx. This marvel-worthy piece is Mountain Hardwear's Dynotherm Hooded Down Jacket. Consider it a rare breed in the world of down jackets, a sort of non-avian, feathered dinosaur that's made for keeping you warm, even when wet.

Built for those unexpectedly-awful crag days or cool evenings spent hanging around the campfire, this lightweight 650-fill down jacket is crafted with a durable ripstop fabric and the uniquely water resistant Q.Shield Down insulation. Each down filament is coated with a DWR treatment, ensuring that you stay cozy-warm through those unanticipated, damp cold fronts. The double-need stitching adds durability, style and texture while low-profiled hood and dual hem drawcords seal in warmth. Equipped with pack compatible chest and hand warmer pockets, this jacket caters to whatever adventure you choose embark upon.

Great puffy, working terriffic

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Large

I am at 6500 ft here in Colorado. Never gets insane cold here which directed me to this down jacket. This puffy is perfect for me, in that it isnt super thick like the800 fill options, but still plenty warm. I mainly wear it out and about to and from work, or for whatever else outside. Hood is insulated and form fitting around your head, no room for over a helmet or anything.

Temps recently dropping down to single digits, keeps me perfectly warm. If you are looking for a packable , super lightweight, super insulated puffy to climb peaks and ski northern rockies temps i would look at a higher price point. But if your needs are simple like me this thing is amazing.

Large has extra room in case i fatten up :) Medium probably would have been too small. It might run a tiny bit large.

On sizing, I'm 6'0" and 160, with long arms. Would you recommend the Large or the Medium? Thanks for the review!

This jacket is true to fit and maintains fantastic warmth even when wet.

I'm 6' 2", 190 lbs with 37" sleeve length. What size jacket will fit best, a large or extra large?


Large is my best, educated guess for you. If you need to make exchange, I could set that all up for you. Just let me know! You can reach me by phone or email. 801.746.7587

Perfect fit.

I tried and returned 4 other similar jackets because the fit wasn't right e.g. arm pits too tight, too long in the torso, arms too short, too much room around the waist. It is not a cold weather (20's) jacket unless you wear a layer under it. it's Mountain Hardware so the quality is top shelf. Don't know why I try other brands :-) :-)

Hello Benji,
What about the quality of the zippers and the stitches?
I'm planning to buy this jacket for winter camping in temps that don't drop below 20. what's your feedback?
