Mountain Equipment Dewline Hooded Down Jacket - Men's

A light and warm winter do-it-all.

That pre-dawn parking-lot gathering is scientifically proven to be the coldest place on Earth, barely beating out the first five minutes on the skin track and the initial pitch of January ice, and it's for these environments that Mountain Equipment designed the Dewline Men's Hooded Down Jacket. It walks a fine line between heavier down jackets and lighter layering pieces, so you can wear it alone or under a shell as conditions warrant, and packs enough water-resistant 700-fill down to keep you comfortable on moderately cold afternoons or murderously frigid mornings. The down is held in place by the Helium 30 fabric, which is lightweight but supremely durable, and by the stitch-through construction, which prevents the feathers from migrating and leaving you with cold spots. The Dewline's Lycra-bound cuffs, hood, and adjustable hem seal in heat and lock out drafts, and the whole package stuffs conveniently into the inner pocket for easy transport and storage.

    I'm shopping the spring sales for a jacket to use on a mid-October trip in the Sierras at 10,000 feet. I tried this and returned it so I can only comment on size and features. I'm 6 feet and 150 lbs and the medium was a good fit, the sleeves are exactly the right length and the body goes just to the bottom of my butt. There is some extra room in the body for layers or if you're heavier than me. The hood fits great without a helmet. Raising your arms up does raise the hem of the jacket and your head turns within the hood rather than the hood turning (but this happens with all the jackets I've tried). The hood is very puffy and warm especially on the top of your head. The fabric is light, has a good feel and seems to be down proof and like it would be strong enough for normal use. The toggles, elastic cord and zippers actually seem more heavy duty than they need to be for a light jacket. There are zippered handwarmer pockets on the outside and a large zippered pocket on the inside left. There are toggles on the hem on each side with ridiculously long elastic cords. There is a single toggle on the upper back of the hood that tightens the hood like a headband (there is no way to tighten the opening around your face). The toggle on the back of the hood seems high enough that your head is not hitting it when laying down. The main zipper slider is on the L side which I think is a UK thing and is a little annoying. The reason I am returning the jacket is that there is not enough loft to convince me that it will be warm enough. Despite the manufacturer's claim of 191 grams (6.8 ounces) of 700 FP down the double layer loft is barely 2 inches, which is less than a Montbell Alpine Light jacket I already own. And this is after hanging in my closet for a while, not right out of the bag. I'm not sure if this is because the style these days is for jackets to be less puffy. The total weight of my size medium jacket is 15.5 ounces. And remember it's not cold enough now for me to really compare or test jackets in the 20 degrees F I'm expecting this fall.

    Sad that you only gave 3 stars to a jacket that you THINK may not be warm enough without having tried it. Down is warmer now than in the past (genetic engineering!) so you should try the less puffy jackets with confidence. This is a 5 star company that really knows its stuff. By the way, I am not an employee but have owned ME Equipment since the 1970's.

    I agree with everything in this review. I just bought this jacket and the sleeves provide about 2" of loft, while the body only provides about 1.75" of loft. And the loft that's there is not resilient to compression. It doesn't rebound well when you squeeze it. I think this is due to the fact that ME used 700FP duck down that's treated with a hydrophobic coating.

    For example, my Rab Electron jacket has 2.5" of loft in the body and about 2.75" in the arms. The Electron and the Dewline both have ~7oz. of down. My Golite Bitterroot jacket provides the same loft as the Electron, but only has 5oz of down. I guess I'm underwhelmed.

    And to reply to Paul R: With all due respect, genetic engineering can't change the physics of insulation. Down insulates by trapping air volume. All things being equal, a less lofty jacket means less insulation. The Dewline feels noticeably less warm than the other jackets I mentioned, and it's either because ME is inflating the amount of down or because it's of inferior quality.

    The one thing that is very lofty on my Dewline is the hood. It's probably 2x as lofty as the rest of the jacket. I wish they could have filled the body and sleeves to the same degree.

    Warmest Down I've had

    I have had many many down jackets. I've worn out a lot of them, and I have lost a lot of them. The Dewline takes the cake for warmth, comfort, and fit. From an everyday jacket to extremely cold temperatures this has held up to the test. I wouldn't recommend it for 30-50 degree days when you are going to be working up a sweat, but for every other time it is my go-to. I typically bring it along on ski tours, leave the car with it on and take it off once I start working up a sweat. I throw it in my pack along with wet skins, wet gloves and it still holds its warmth amazingly well when I pull it out again to toss on at the peak. Anyone in the market for a down jacket needs to consider Mountain Equipment's expertise and give them a try! (If you can believe it... ME's down engineer has a PhD in Down)

    Great purchase

    Was exactly what I was looking a great middle warmth coat perfect for under my shell on winter hikes although it's warm enough for a everyday winter coat I live in Massachusetts and I almost never need my heavyweight winter parka this coat is super lightweight and seems very durable I've always bought Patagonia, arcteryx, and north face products but I am a new fan to mountain equipment I am 6ft 175 pounds and the large fit perfect I highly recommend this coat and the quality is on par with far more expensive jackets very happy with this purchase.

    Is this jacket windproof like the lightline?


    The Dewline uses the Helium 30 fabric which is going to be wind-resistant. The face fabric on the Lightline is a DriLite Loft fabric which is windproof and water-resistant.

    Definitely contact me with any questions you've got.

    Always makes my pack

    If you're a winter outdoor person, you know the moment: sorting gear the night before, or maybe the morning of, and wondering whether you really want that bigger puffy for the day. Weighing bulk against warm, size against weight, it can be a struggle.

    But with the Dewline, I'm never at a loss. It packs more down into the same mid-size down coat that nicely fills the gap between a down sweater and an expedition parka. It's small when stuffed into its own pocket. From cold inbounds days to snow camping on Rainier in March, I used this thing hard last winter in temps that usually would have me scurrying for something more substantial.

    And if you're feeling brave, go for the Minium. It's bright.

    Sizing runs on the trim, athletic side, so if you're a man of girth, perhaps consider sizing up.

    I am tied between this jacket and the Patagonia Down Sweater. i have a few questions. How does it compared to the down sweater in durability, warmth, and pack-ability?

    Hey Rich! you may have already pulled the trigger but just came across your question.

    Regarding Warmth. The Mountain Equipment jacket has a lot less stitching and bigger stitched through baffles making it considerable warmer

    Regarding Durability the face fabric on the Mountain Equipment Jacket is the same face fabric used on the ME sleeping bags. It breaths great to.

    Regarding packability The Mountain Equipment coat has a bit more down and with the bigger baffles it doesn't get as small but still the ME jacket gets very small and is a great bag stuffer to. Sorry I don't have more information about the Patagonia jacket all I have is ME stuff. hope that helps


    I'd love to help and offer a few different perspectives. Sam had some really great points. When it comes to the two jackets, the bigger baffles on the ME Dewline is going to help big time in the warmth department. The Patagonia piece is more fashion oriented so they went with smaller baffles. Don't get me wrong, I've got jackets with smaller baffles but those jackets are not my go-to's for the cold days.

    For durability, I'd peg the Helium 30 fabric to win out over the 20-30 denier fabric on the Patagonia piece.

    But the big difference between these two pieces is fit. I'd love to chat with you about your build and I can help show you how this piece and Mountain Equipment as a brand does a great job with their fit.

    Definitely contact me with any questions you've got.
