Lightline Down Jacket

Designed to meet the needs of mountaineers who routinely spend time in harsh alpine environments, the Mountain Equipment Lightline Down Jacket is designed to shield you from the cold when staying warm isn't just preferable, but essential. The windproof and water-resistant DryLite outer shell is packed full of 700-fill down, stitched in horizontal baffles to ensure that the insulation stays where you need it most. The down itself is an incredibly warm 90% down/10% feather mixture, which is the warmest down/feather ratio generally commercially available. Mountain Equipment gave the Lightline a fully-adjustable zip-off hood so you can trim weight if you need to, and used stitched-through construction to ensure that it isn't carrying any extra bulk that can be a hassle on serious alpine expeditions. An insulated baffle sits behind the zipper to prevent drafts and heat loss, and the zippered hand pockets are covered by insulated flaps for the same reason.

  • 700-fill down (90% down/10% feathers)
  • DriLite windproof and water-resistant outer fabric
  • Stitched-through horizontal baffles
  • Fully-adjustable 3-panel zip-off hood
  • Insulated baffle behind front zipper
  • Insulated flaps cover the handwarmer pockets
  • Adjustable cuffs and hem drawcord

Way warmer than I expected

I got this jacket a few weeks ago and hadn't been able to test it due to a warm winter. These past couple days our temperatures dropped, and today I decided to go on a little photoshoot with my family in the canyon. Temps dropped to -11F (yes that's -11 degrees Fahrenheit) with a windchill warning and the sun had already dropped, I decided to put it to the test and only wore a short sleeve shirt underneath. This jacket kept me so warm, I forgot it was -11F until I took my hands out of my pockets and they froze after just a few seconds. I spent around an hour or more standing at the same place, sometimes walking but nothing to increase my heart rate, and was still incredibly warm. The jacket is very well made and fits like a charm, I could've gotten away with a small but I've been super happy with a medium. The jacket is also stronger and more durable than I expected it to be. After several uses, I haven't had problems with the zipper, as Peter M mentioned below, you just have to make sure they engage well first.

I did test it several more times around the 20-30º range with just a shirt and I got too hot and had to zip it open to vent a bit. I tend to run a bit cold as well but I'm extremely happy to have found this jacket.

Almost Perfect

Looked around quite a bit and read review after review before I bought this jacket. It was to replace a 20 year old goose down puffer jacket that is aging gracefully. Love the style of the Mtn. Equip. Lightline jacket.

Wore it for a few days in 30°F, wet snow mostly. It repelled most of the wet very well. Windproof as advertised. Pretty sure this jacket is meant to be worn as part of a layer system. I want to add my confusion as to why the zipper is so small. Hard to zip without looking down and fumbling with it. Don't let it be a deal breaker though. My shoulders got cold and I could tell the jacket was at the edge of it's warmth with a t-shirt on underneath at 30°, not unbearable and should be good for most applications but we get some pretty low temps here in Michigan and I've been spoiled by my old jacket.

I did return it, which was smooth as silk. Great customer service.

Reported zipper prob. ..other reviewers

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

Some reviews have complained of the zipper design…

The jacket has a very good zipper of European design… But it takes a while to understand how it functions… Press both zippers on left side down all the way until you feel them engaging..then set the right side in all the way… Hold and pull up…
Once you get the hang of it it’s just as fast and zipper quality is actually way superior to other jackets…have had a favorite jackets from Patagonia etc..… Their zippers had to be replaced…

I have had similar jackets from Patagonia, Arc’teryx, etc.....This may not be as lightweight as other jackets but it’s superior in its warmth.. The hood quality is fantastic…If you pull the zipper all the way up, your neck and chest stay very toasty in windy, cold weather…
It’s also roomy enough to put a middle layer underneath if you need it…

Hope it’s been helpful folks!

Great Winter Down Jacket

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

This jacket is very well constructed and very warm, especially for the it's price range. I wore it in 15 F weather last week with only a t-shirt underneath and I was toasty. I really like the removable hood so I don't have a bunch of hoods to deal with when I use this as a mid layer. The size medium allows me to wear this jacket as a mid layer or on top as a belay jacket (although it is a little tight around the chest area for this). The jacket is rather large when packed down especially if you compare it to a lightweight down jacket. However, you will actually be warm in this jacket below freezing and not just pretending like someone wearing a down sweater.

Nice coat. Great looks. Little Heavy.

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: XL

This is a really solid looking coat. The combination of down and other insulation makes it a little heavier than a typical down jacket, but if you don't care it makes up for it with features. It has a nice expedition look to it if you want a solid looking piece of gear to wear around town and out for dog walks. On the hill it also seems like it would be plenty warm, but maybe not the warmest down jacket out there. The removeable hood is nice, but also adds extra hardware that adds weight and bulk around the neck. Still, the hood works great and the jacket looks nice with it off as well. The removeable hood can lay flatter than other hoods because the neck flaps detach from the collar.

I was looking for a lightweight packable down jacket, and while this can be packed down, it wasn't exactly what I had in mind. The Marmot Guides is still hands-down the best jacket in the price range.

Nice puffer!

Just got this jacket and it's awesome. Super warm. It has a trim fit so you can put a water proof shell over it without looking too marshmallow like. Derachable hood is a very nice feature as well. Im 180 lbs and 5' 10" and the medium is perfect. Great price too!

This 700-down puffer will keep you warm when you really need it. I picked this bad boy up just before a cold snap hit in Utah. My friends were all freezing because they weren't prepared for the winter cold, but I was sitting pretty wrapped up in this. It even comes with a bag it packs in to, which really came in handy when I ended up having to shed layers during a snow hike that went in to the afternoon. The removable hood was nice, too, when I decided to put an extra waterproof layer over top in some heavy precipitation one evening, to keep it out of the way.

An excellent coat, I'm glad I bought one

  • Familiarity: I've put it through the wringer
  • Fit: Runs small
  • Size Bought: XXL

This coat runs small. I'm 6' over 230 lb and usually I would wear an XL but for this coat I ordered the XXL and it is perfect. I really just have 1 small issue with the coat which is the zipper. Yes, its "backwards" (on the left) but that is OK with me. It's just a thin, flimsy zipper, that doesn't seem to match the quality of the rest of the coat. If Mountain Equipment put a better zipper on there that was maybe slightly bigger and more durable, it would be flawless. The coat is warm, comfortable, stylish, durable, with plenty of space in the pockets. Like, you can easily fit a 6 pack of beer by putting 3 cans in 1 pocket and 3 cans in the other. I just came in from -10 wind chill outside and the coat kept me very warm and comfortable. Besides a little frustration about the zipper, a minor issue, I am really enjoying this coat and I'm so glad that I purchased it.

Hi Ryan,

Thanks for the review! The zipper on this coat is a tooth zipper rather than the typical spiral zipper you normally see on clothing. Not only is a tooth zipper tougher than a standard spiral it will still function if you do manage to break a tooth or two.

Fantastic cold-weather jacket

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

It's hard to find anything *not* to love about this jacket. Loads of high-quality down, extremely warm (I regularly wear it w/o a base layer in sub zero Celsius temps), stops wind, decent water resistance, light, good fit (trimmer than the Rab Neutrino; less "Hothian" than the North Face Gotham). And the price! Minor nits: no external chest pocket; as others point out, the zipper is "backwards" compared to most US jackets (which is typical for UK jackets).

get this jacket!

  • Familiarity: I've used it several times

  • Size Bought: large

I was trying to decide on a good all around jacket for winter camping and hiking, and just something for my days up in mountain towns. Shopping around between the usual big brands, there's always a choice between a hoody and a jacket. Why not get a jacket with a removable hood at the same price? The quality of this jacket is great. There's a lot of loft, the hood doesn't pull back on you when you're not wearing it, and the pockets are nicely insulated. I have more technical jackets, but I'm sure I'll be pulling this out time and time again.

Outstanding jacket

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

Having done much research on down jackets came across the Lightline based on reviews worldwide. By far the most value for money in terms of quality 700 down for the price ( >10 oz is a ridiculous amount for the price and found in jackets way north of $500); it seems to be from a quality UK based co. without the marketing mark-up of other US brands. Comfortable down to 0-10F with T-shirt underneath for dog walks during recent Northeast cold blitz. Chose Large partly based on availability, but size does allow for layering underneath and is also perfect with my soft shell on top. Couldn't be happier with my purchase.

Warm, attractive, but with 2 flaws

  • Familiarity: I've used it several times
  • Size Bought: Large

This is a good-looking and comfortable jacket. It's warm and the outer shell just feels good to the touch. Deep pockets are nice and insulated. Love the removable hood. Puffy, but not TOO much... and super light! I am 6'0 181 lbs and found the large to be a bit on the small side. If you want to wear anything other than just a shirt underneath, I found it a bit too snug for me. Now, the drawbacks. The primary zipper is ridiculous for a man's jacket. It's a tiny little thing... something like you'd find on a woman's zip sweater. And the reverse-side placement of it was just a pain. It often took a couple of tries to get it to "seat" so it would zip up. Even the pull itself is just a tiny little cord. Just seems like the zipper was designed for a woman's coat. The low-price coat I was replacing that I bought at Kohl's 2 years ago has a zipper and grippy pull that puts it to shame. The pocket zippers were equally as tiny and difficult because they often caught the fabric on the sides when zipping them up. Frustrating. If these things don't really bother you, then by all means give it a shot. BackCountry made it easy for me to return for these reasons and I ordered another coat instead. It's a shame because it looks good... is warm... and has other nice features. Why the heck a coat with a 40-year history has these simple-to-fix zipper issues is beyond me. In any event, I recommend BackCountry and their great customer service!

Great Fit and Removeable Hood

Love this coat it is so warm and the removable hood is awesome!

Great jacket, runs small

  • Familiarity: I've put it through the wringer
  • Fit: Runs small
  • Size Bought: large

UPDATE - wear it all the time for over a year. Holding up very well.
Very warm and comfy. It does run small - I can barely zip it shut over my belly. I do like that the arms and shoulders are long enough for me. I wish it had more pockets, it only has 1 inside zip and the 2 zippered handwarmer pockets on the front. Doesn't really have ski/snowboard features but that's OK with me.
( I bought an XL for Hubby. He's 6'3, 200 # and it was too small)

Legendary down jacket.

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

I work for ME and the Lightline is a legend within the business, the first version was made back in the early 70's, the current one is the best yet and our most popular jacket. They're being used somewhere in the world every day of the year, from Himalayan peaks to ski days and digging out the truck! The Drilite Loft fabric is impressively weatherproof [1500mm hydrostatic head] and the down is audited for animal welfare and quality through our industry first Down Codex system. A great down jacket that many people buy for a big trip and end up wearing every day of the winter!

Great Puffy Puffy

  • Familiarity: I've put it through the wringer

Jacket is very warm and comfy and love that the hood is fully insulated. Only complaint is that the zipper is on the left side which makes it annoying to zip up.

Like wearing a warm, fitted blanket

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: Medium

Was looking for something to replace my heavy weight down jacket. Have not had any experience with Mountain Equipment in the past. This is an upgrade. Very lofty. It has to be rather cold to use it (sub 20-30F), which is a shame as the liner fabric makes this the most comfortable insulator jacket I've come across. It doesn't give me that cold nylon against skin feeling when you put it on, but is soft and warm to the touch. It feels like you're wrapped in a blank. Also appreciate the fully insulated hood compared to other jackets skimping there. Great fit too. A little bit trim and longer cut. It'd be nice to be able to pack this into a pocket instead of the included stuff sack but perhaps there are too many feathers here to be practical. I may have to check out their lighter weight offering as the comfort of this material is hard to beat.

Great fit & finish

  • Fit: True to size
  • Size Bought: Extra Large

6'3", 225lbs, 46 in chest. Fantastic fit...not too puffy and you can really feel all of the down they've packed inside of the baffles. Will follow up with a more detailed review once the temperature drops and I need to wear this jacket, but I'm incredibly pleased with the fit - somewhat athletic as others have noted - and the perceived quality. Honestly this seems more like a more expensive down jacket than it's listed price. I can see no need to break this jacket out at anything above 32°F...even then, you probably wouldn't need it until the mid 20s, unless of course you're belaying or stuck stationary. Definitely looks good enough for day-to-day in the cold waiting for the train to work; then, you can turn around and use it for your weekend winter hike up Mt. Washington or wherever. Special thank you to Nicholas for helping me out and I fully intend to enjoy the outdoors with this jacket!

EDIT: curious why lists the fill power for this jacket at 675 when the manufacturer and other sites list the fill power at 700. I attached a picture from the tag from my jacket. There's only one standard for testing fill power now so I'm unsure why there's a discrepancy.

Great fit & finish

nicest I have seen in years

  • Familiarity: I returned this product before using it

this is the nicest light weight down jacket i have seen in years! Too bad its cut so small---I had to return it
