Hadron: The new king of warmth for those who call the mountains home.

At just seven-ounces light, the Stoic Men's Hadron Down Cardigan packs a powerful warmth-to-weight ratio that makes your other synthetic-insulated jacket look foolish in comparison. And honestly, how could your other jacket compete with the Hadron Cardigan's 850-fill goose down insulation and highly-breathable Pertex Quantum shell fabric? Stoic even gave this packable layer a 3-D ergonomic fit for supreme freedom of movement when you're touring or climbing, or even when you're whipping up a late meal at base camp.
  • Down insulation and cardigan-style cut allows this jacket to pack down to the size of a water bottle for supreme stowability
  • 3-D Ergonomic fit makes for a more active, athletic fit that won't ride up and expose your skin to the cold

great packable down puffy

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

have had this jacket with the hood now for coming on 3 years. Worn this thing sooo many times whether i was snow camping, or camping in the summer or just around the house on cold days to doing multipitch climbs.. super lightweight and warm. no tears or scratches. Nice snug fit for layering, super key for me. Has lost an exceptional amount of the down feathers, but that just happens so oh well. my only con is the colors are a little to stand out, but if your cool with that. its a great deal when on sale! i think its way worth it!

I was a bit suspicious about this jacket when it finally arrived. It did not seem to be filled with a lots of dawn. However, I took it 'in a field' couple of times, and I have to say this is so far one of the best buys. Very warm, very light, good size; I've got skinny wrists, so it wasn't too tight there. Outer fabric feels super delicate, but turned out to be very durable (couple of nasty landings after slipping on wet tree roots). Actually it kind of amazes me how can it be that strong given how thin it is. The only one thing I could complain about is that it's not a zip neck, and when it's very windy, a wind can slip into the jacket through the neck part.

+ weight,
+ durability,
+ warmth,
+ packability,
+ drawcord,
+ nice inside pocket,

- Not a zip neck (some would argue as this being a con)

Does Stoic use treated down for water...

Does Stoic use treated down for water resistance and durability? If so, can you provide any links to where I can find more information on the process/quality of the treatment? Thanks!

Best Answer Responded on

Stoic does not currently use hydrophobic down. The Hadron Down Cardigan does have a Pertex Quantum fabric though, which is a very durable and extremely lightweight fabric that is often touted as downproof as well as windproof due to the dense weave. The fabric is not waterproof though, because it would limit the fabrics intended high breathability, which also allows the down to loft more fully.

Solid piece

  • Gender: Male
  • Familiarity: I've used it several times

I'm 5'6" 155lbs. 37" chest, 15.5" neck. Medium fit well with a t-shirt underneath. Length is halfway covering my butt. Neck isn't snug but not loose. Cut is pretty square.
Snaps are very nice - enjoyable change from a zipper that irritates your neck. First putting it on, the wrist's are very tight.. but they relax quickly,just a bit, and are very comfortable.
I spend the week skiing in a t-shirt and this puff in dry conditions around -5C to 7C in low wind. Almost perfect. Due to the wrist, the arms get toasty. (but only if it's really sunny out) It's so light it makes you feel naturally warm - not "wearing a bunch of clothes warm."
Possible improvement: zippers on the kangaroo pocket. I haven't had things fall out, but it'd be a nice bit of security.
Overall, I'm thrilled with the value of the purchase. Keep it up Stoic.

Compactable and warm

I love this puffy! As a base layer under a shell, or as an external layer on a warmer day this gets the job done at a great price. Havent been cold yet this year and have been out on some 2 deg. F days.

Awesome cardigan/anorak

  • Gender: Male
  • Familiarity: I've put it through the wringer

This thing is so warm, I've been wearing it for the past two weeks in the negatives and the 20s and teens, and it's been great. The only real downside is that it's a pullover, which can be a bit annoying sometimes trying to wrangle myself into it. As others have said, the cuffs are unusually tight, which is nice when snowboarding it and wearing it under a shell, but is a bit annoying when wearing it on its own. I'll probably just end up cutting the cuff elastic and replacing it with something looser. I also hope that Stoic will make this again next year with a full zip, as that would make it more convenient as with their down vest which I also own.

love the weight to cost ratio

  • Gender: Male
  • Familiarity: I've used it several times

I bought last years model on sale, and have to say that I love it. The only reason I didn't give it 5 stars is that the arms were a little narrow, but overall it is not a major concern. I have taken this on a 6 night hike in the sierras this last summer, where temperatures at Mt. Whitney were in the high 30's, and this jacket did the trick...though I did have a couple of layers of shirts underneath. really happy with my purchase and would recommend to anyone.

Great Puffy, just not for me.

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

I'm 6'2" and hover around ~180 pounds.
I ordered the large and it fit pretty well. Loose in the chest and close to being to short in length. At first the length bothered me, but it's perfect for fitting underneath the shell.
The colors really aren't that bad, I actually really like the orange.
I had to return it however. I don't carry the warmest sleeping bag ever so that it's easier to carry on my bike. I'm looking for a warmer jacket to make up for the fact that my bag is too short. This one's great if all you're doing in it is wearing it around camp and being active.

5'6" 150 lbs. 37"chest average build. Thought's on sizing?? Does Stoic run small/large? Thanks!

Responded on

I am 6'0" 160lbs and ordered a medium. The fit is great. Length to torso when arms are not raised is good. The bottom of the jacket may rise when the arms are raised, but there is a drawcord to help this problem. Typically this is a layer under a waterproof shell, and it functions perfectly in this respect. Overall sizing, the medium I ordered seems on par with most anything else medium that I order.

Not bulky, warm as toast, rolls into a small ball. There is nothing not to love about this item.

Warm Jacket

  • Familiarity: I've put it through the wringer

Nice fit, light and warm. Wrist bands are tight, but they keep the snow and weather out.

I love the packability of this, I'm a night time city bike rider, and I can peel this layer off once I get warm enough from pedaling and it fits into my medium novara under seat bag... It's nice to not have to freeze through the first bit o ride, or have to carry a pack for shed gear.
It is not an around the town piece though, way to crunchy sounding and the purple is way to shiny for me to pull off in any social situation.

Is there a temperature rating for this...

Is there a temperature rating for this coat?

Responded on

They don't typically do temperature ratings for coats since it depends on the body type and activity, but with 850 goose fill you'll be nice and warm.

Good but lacking

I really like this jacket for a couple of reasons. For one it is very warm and for two it is very light. That said, it has a big flaw for me, the elastic cuffs at the wrist are too tight and the stretch material itself feels like sandpaper against my skin. It seems like it should have been nixed in favor of a softer stretchier fabric. I am 6' and 170lbs so maybe a large would have fit better in the wrist but the medium is perfect everywhere else. So, as with all gear that is uncomfortable for me, it goes in the loaner/girlfriend bin. Stoic was really close to making a perfect jacket.

Responded on

I agree with this reviewer that an elastic cuff using the same quantum pertex, smoother material would be preferable and that the current cuff is too tight. Overall, still a great garment.

Responded on

Yes, the cuffs are too tight, but I am really HOPING it helps keep me warm through the night on the Badger Mountain 100. 35-40 degrees at night... wonder if I need something warmer?

light, packable, and warm

This is a great layering piece. For the sale price, I don't think that there's anything better. The construction is solid, the fill is uniform and the fit is about right. I'm 6'1" and have a long torso and arms and aside from slight bagginess in the body, the large fits great. The elastic wristbands are a bit odd at first but I ended up really liking them, though they are a little tight even on my narrowish wrists. I love the purple color and the pertex fabric. I wore this as my only insulating layer on a three day through hike in the Olympic National Forest. Being a rain forest, the weather was wet, and because our summer started so late here, I was in snow for one of the days and near the snow level on another. Even with temps into the low thirties, gusting winds and a lot of ambient moisture, as well as pouring rain, the jacket kept me plenty warm with just an OR Helium rain jacket over the top of it. I absolutely recommend this to anyone looking for a good insulating piece. It performed great even in some of the worst wet weather circumstances you're likely to come across short of a tropical storm.

Nice pullover

Super light and compressable. I got the green color. Definitely kind of bright. I am afraid if I drop it in the outfield, I may never find it again. But, it'll be perfect for St. Patty's Day!

Compresses really small

This jacket is lightweight and compresses down really small! Throw it in your pack and forget about it! Pull it out when it gets cold and throw a shell over it when it starts raining and blowing and stay warm! :)
