A staple in the Mountain Equipment lineup for over 40 years, the Lightline packs a serious punch. This winter-weight jacket is very warm with over 10 ounces of 700-fill-power down and has a tough 40-denier shell, all for less than $300. Taken together, you won’t find a better value and it’s one of our favorite down jackets for frigid days. Below we break down the Mountain Equipment Lightline’s warmth, weather resistance, weight, durabilityfit and sizing, and more. To see how it stacks up to the competition, see our articles on the best down jackets and best winter jackets.


Performance

Warmth

The Mountain Equipment Lightline is a serious down jacket built for sub-freezing temperatures and deep winter conditions. What makes it so warm? To start, it’s stuffed with a lot of 700-fill duck down—10.4 ounces to be exact. For comparison, popular models in the same category such as the Rab Neutrino Pro and Patagonia Fitz Roy both use 8 ounces of down, although theirs is higher-end 800-fill-power. Second, the Lightline has a burly 40-denier shell that does a great job of keeping warmth in and snow out. Finally, the hood (described in more detail below) deftly keeps wind at bay. From daily use to winter camping adventures, the Lightline should keep you cozy.

The Lightline is so warm in fact, that it’s overkill for anything but the coldest environments. After multiple winters with the jacket, we have found it to be most comfortable when temperatures dip well below freezing. With just a t-shirt on underneath—our preferred use given the super-soft interior—the jacket easily kept me warm during light activity in temperatures hovering around 20 degrees Fahrenheit. And when the mercury reaches single digits or lower, pairing it with a light midlayer is a nice combination. What’s perhaps most impressive, however, is that the Lightline is able to provide this level of warmth for just $275—a significantly lower price than comparable winter down jackets.

Weather Resistance

The Mountain Equipment Lightline offers excellent protection in cold, snowy, and windy conditions. The healthy amount of down fill combined with the thick 40-denier Drilite shell fabric do an admiral job of cutting wind, making the jacket feel nearly fortress-like in strong gusts (the stitched-through construction technically leaves vulnerabilities, but it'd take some serious wind to be noticeable). Further, a polyurethane coating helps moisture bead up and roll off the surface rather than penetrating the shell. And the hood is the icing on the cake: it contours nicely around my head and offers plenty of adjustments for battening down the hatches. Finally, the wire brim adds protection and visibility, and is even removable should that be your preference. One downside for climbers and skiers: the hood does makes for a tight fit around a helmet, although it technically works.

The biggest enemy of down is moisture. When wet, it loses its loft and ability to insulate. In addition to the shell fabric and coating described above, it’s worth mentioning that the competing Rab Neutrino Pro uses hydrophobic down, which allows it to resist moisture even further and retain some loft even when exposed to the elements. Unfortunately, the Lightline does not have hydrophobic down, which is a reality given its low price point. But no down piece is made to truly excel in wet environments, and for those we would choose a synthetic jacket (or layer with a hardshell overtop).

Weight and Packability

On my scale, the men’s Lightline in a size medium came in at 1 pound 9 ounces (the advertised weight is 1 lb. 10.1 oz.). For a jacket intended for backcountry use—even a winter design—this is by no means lightweight. Similarly warm jackets like the Rab Neutrino Pro (1 lb. 5.3 oz.) and Patagonia Fitz Roy (1 lb. 6.3 oz.) easily undercut the Lightline, but they do so at the expense of durability and cost. With the Mountain Equipment you get a tougher 40-denier face fabric which is less likely to develop abrasions and stains over time (an issue we've had with the Fitz Roy). In the end, your decision likely will come down to priorities: climbers and skiers might opt for the lighter options, but the Lightline is a great workhorse for everyday and even technical use.

Despite its relatively heavy-duty construction and use of 700-fill down (which isn’t as compressible as higher-end options), the Lightline packs down surprising well. Although not exactly compact, the jacket is relatively easy to fit into the included stuff sack and measures about 7 x 10 inches when packed (it fits nicely into the bottom of a medium-sized daypack). For comparison, the performance-oriented Neutrino Pro includes a stuff sack of the same size, but the 800-fill down and thinner fabric compact slightly smaller than the Lightline.

Construction and Durability

If you’re looking for a relatively inexpensive dead-of-winter jacket that should last through multiple seasons, you’d be hard pressed to find a better option than the Lightline. The shell fabric is refreshingly burly to the touch and shows no signs of wear after many winter days, the zippers operate smoothly and are easy to use (provided you can adjust to the European left hand main zipper), and there isn’t a stitch or seam out of place. And despite a number of backcountry outings and being stuffed away into packs and duffels, the jacket doesn’t look overly dirty or grimy. The Lightline is going into its third winter of testing here at Switchback Travel and it still looks and functions like new.

When compared to other popular and similarly intentioned models like the Rab Neutrino Pro and Patagonia Fitz Roy, the Mountain Equipment Lightline offers a step up in durability. Those two jackets both weigh less and pack down smaller, but they also use a thinner 20-denier face fabric, which feels noticeably less robust than the Lightline’s shell. Our Fitz Roy (which features Pertex Quantum rather than the Rab’s polyurethane-coated Pertex Quantum Pro) has seen a large number of tears and stains in just its first few months of use. As my own adventures have grown in distance and vertical feet, I’ve turned to ultralight gear and apparel to ease the burden. However, putting on the more hardwearing Lightline was a nice reminder that durable gear definitely has its merits.Mountain Equipment Lightline (front 2)


Features: Hood, Pockets, and Cuffs

In terms of features, Mountain Equipment kept it simple. The 3-panel, removable hood is appropriately sized for use with or without a helmet, and the wire brim helps to keep blowing snow out of your face. While the drawcord adjustments and rear Velcro are easy to use with gloves on, we do find that the exposed nature of these cords looks busy and lacks the finish of similar jackets from Rab and Patagonia (who hide their adjustments for a streamlined look). But its functionality is great: the hood cinches down to hug my face and feels well-protected from heavy winds.

In terms of storage, the Lightline has two hand pockets that are nicely sized for small essentials like a headlamp or snacks. These handwarmer pockets have insulation on the outside of the jacket and offer a safe haven for the cold. In addition, I really like the internal zip pocket on the chest, which is the ideal place to keep my phone warm. The lack of dump pockets—a great place to store skins or winter gloves—is one notable omission for technical use, but I’ve gotten along just fine without them for now. Finally, the cuffs are easy to use and feature a generous amount of Velcro to wear over or under gloves to keep the cold at bay.

Fit and Sizing

This was my first foray with U.K.-based Mountain Equipment, and I’m happy to report that the fit of my standard men’s medium was spot on (for reference, I’m about 5’9” and 160 pounds). I’d consider the fit “athletic”—the ME Lightline afforded me just enough room to wear a substantial midlayer underneath, but it wasn’t so large that it hung off my body with just a t-shirt or thin baselayer on (the trim fit also helps with heating efficiency). And although it has quite a bit of loft, I was easily able to slip my ski shell on overtop, which is not always the case in this category. If you are on the fence between sizes or plan on layering heavily underneath, you may want to consider sizing up, but we love the fit of the Lightline overall.

Other Versions of the Lightline Jacket

I reviewed the men’s version of the Lightline here, but Mountain Equipment also makes the jacket in a women’s-specific version. With slight differences in cut and baffle design that arc toward the top of the jacket (the baffles on the men’s version are horizontal), the women’s Lightline has a lower fill weight (8 ounces vs. 10.4 ounces for the men’s), but both use the same 700-fill-power down, 40-denier Drilite Loft shell fabric, and are priced at $275. Mountain Equipment does not make a hoodless version of the Lightline—you’ll have to step down to the lightweight Odin or Earthrise for that. 
 

Sustainability: Responsibly Sourced Duck Down (Down Codex)

An interesting fact about Mountain Equipment is that they’ve been pursuing the use of responsibly sourced down for years. Originally launched in 2012, their Down Codex project brings transparency to every element of the feathers’ journey. Each jacket comes with a tag and a 12-digit code sewn on the inside—enter the code on ME’s Down Codex website, and you can find the complete history of the down, an audit and risk assessment, and even the exact content and fill. This differs from the Responsible Down Standard (RDS) commonly used in the U.S., but kudos to Mountain Equipment for prioritizing sustainability with this informative resource.Mountain Equipment Lightline (cabin)


What We Like

  • The Mountain Equipment Lightline is very warm, durable, and significantly undercuts most of the competition in price. All in all, it’s one of our favorite cold-weather down jackets.
  • 40-denier face fabric is much more durable than most of the competition.
  • Athletic fit and super soft interior is great for both in-town and backcountry use.


What We Don’t

  • The Lightline on the heavy end for a down winter jacket and not our first choice for fast-and-light outings.
  • The 700-fill-power down doesn’t quite have the same compressibility or warmth-to-weight ratio as the 800-fill Rab Neutrino Pro or Patagonia Fitz Roy.
  • Not as weather resistant as models that use hydrophobic down (although its robust shell and polyurethane coating help it hold up pretty well).
  • Overkill for anything but sub-freezing temperatures.

The Competition

The Mountain Equipment Lightline is a great value in a down jacket that works well for both casual and backcountry use. For a similarly warm jacket with a slightly more technical slant, the Rab Neutrino Pro is another great option. Compared to the Lightline, the Neutrino Pro uses higher-quality 800-fill hydrophobic down and is constructed with a thinner 20-denier Pertex Quantum Pro face fabric, both of which make it more packable. Additionally, the Neutrino Pro is a significant 5 ounces lighter despite being filled with a healthy 8 ounces of down (for more, see our in-depth review here). All things considered, we prefer the Rab for performance use when ounces matter, but the slightly trimmer-fitting and cheaper Lightline is the better value for less technical endeavors.Mountain Equipment Lightline (lineup)

If you’re in the market for a warm winter jacket worthy of technical outings, chances are high you’ve come across the Patagonia Fitz Roy Parka. Similar to the Rab above, the Patagonia uses 8 ounces of a more premium 800-fill-power down and undercuts the Lightline by about 4 ounces. Beyond the down, a big difference between the two jackets is their shell fabrics: the 40D shell on the Lightline is much more hard-wearing than the Fitz Roy’s thin 20D shell. However, Patagonia’s fit and finish are unmatched and the Fitz Roy has a softer exterior (the interiors are both quite good), but we’re not sure it’s worth it for the drop in durability and increase in price. For $150 less, the Lightline is the longer-lasting option that offers similar warmth.

If the jackets above are too specialized in nature, then the REI Co-op Stormhenge 850 is worth a serious look. For just $249, you get a warm and waterproof winter jacket that can be worn in a variety of inclement weather. Combining premium 850-fill down (REI does not list the fill weight, but we’ve worn the Stormhenge on frigid days in Northern Wisconsin and stayed warm), a 2-layer waterproof breathable shell, and a DWR coating, it’s a great choice for cold and wet conditions. But at 1 pound 11 ounces, the Stormhenge is even heavier than the Lightline and more suited for casual use and light winter adventuring than the backcountry. In the end, the Lightline works better for more serious excursions, but we love the versatility and value of the REI. Mountain Equipment Lightline (town)

Last by not least, Mountain Equipment offers an interesting, lighter-weight alternative to the Lightline in the Skyline. One of our gear editor’s biggest complaints about the Lightline is that it is so warm that it stays in his closet for all but the coldest stretches of winter. The ME Skyline, on the other hand, still is quite cozy with 6.3 ounces of 700-fill down (versus 10.4 ounces on the Lightline), weighs a more reasonable 15.7 ounces, and has a thinner 20-denier shell that is more packable at the sacrifice of some durability. At the end of the day, the Skyline is warmer than popular lightweight down jackets like Arc’teryx Cerium LT and Mountain Hardwear Ghost Whisperer/2, and attractively priced at $240—cheaper than either of those models. It’s true that the Skyline might not get you down to the depths of winter, but it’s great for shoulder seasons and many winter days.
