La Sportiva Lumina 100 Down Jacket

Historically, down jackets have been best suited for sedentary activities or high-alpine pursuits. We’ve all seen climbers on Everest in their ultra-puffy down parkas, but there’s much more to down insulation than that. Ultralight down jackets, like the La Sportiva Lumina 100 Down Jacket, present an option that leverages the best attributes of down in a packable, lightweight and versatile parka.

La Sportiva Lumina 100 Jacket Features:

• Recycled Pertex® Quantum shell
• 70g of 1,000 cu. in. of Italian down
• Diamond-pattern to evenly distribute the down fill
• 2 zippered hand pockets
• Weight: 185 grams (medium, actual)
• MSRP: $239

Lightweight alone, unlocked when layered

The beauty of living in Utah is that our winters are usually snowy, but it’s that cold smoke kind of snow that has much lower water content. With that, down jackets are great for casual or technical wear here and there’s less worry about snow or rain soaking them and rendering the insulation useless. Growing up in the Pacific Northwest, down jackets weren’t really a thing and now I can’t live without them.

Of course, other down jackets do have more weatherproof outer shells, but the Lumina 100 isn’t made for nuclear winds atop a high-altitude peak. No, it’s built for everyday mountain use or as an extra layer that can come along for the ride in even the smallest pack. It can also handle more aerobic activity than a typical down puffy.

The size medium fits just right — with the perfect sleeve and hem length and just the right proportions elsewhere. This is a lightweight jacket, but the insulation is just right for a wide variety of temperatures and conditions. It takes only a few seconds after slipping it on to feel its warmth. With simple cuffs and hem and an unbacked front zipper, the Lumina 100 isn’t made for battening down the hatches in a blustering gale. No, it’s made for cold conditions where a little airflow underneath the hem and through the zipper is welcomed, or stopped with an outer shell.

I appreciate the streamlined fit as a daily driver and as an outer layer for winter hiking. On my hiking loop, the Lumina keeps me warm and cozy and only after about an hour does the perspiration start to saturate the back panel. It does dry out pretty fast, but the Lumina 100 isn’t really meant for long-distance, high-output aerobic activity. A fast-paced hike for 60-90 minutes is about as much as it can handle before getting oversaturated. When hiking with a hydration pack, the pockets are accessible and it feels natural and comfortable.

If you’re just sitting around and not moving, temperatures in the low-30’s will start to get uncomfortable. I’d say it’s best for above-freezing temperatures at night, but you’ll want to keep moving or layer up to stay warm if the temperatures drop below freezing. The black color does add warmth during a sunny, but cold day outside.

Most of the time, I’m a hooded jacket kind of guy. I’m from Seattle, so in my mind, jackets should always have hoods to protect from the rain. The Lumina 100 isn’t offered with a hood, but I actually appreciated that. The collar height and diameter is just right to seal out the elements without being too bulky and awkward — and it works great when layered. I found it to work great with a zip-neck long-sleeve base layer underneath. For skiing or hunkering down, it slides smoothly underneath a hardshell for the ultimate package.

It’s great that La Sportiva includes patches to repair small punctures — not all manufacturers do that. The Pertex Quantum shell has been sturdy enough to handle regular use, but will have problems if abused. There is a reinforced area atop the right shoulder, but not on the left. I’d actually like to see it on both shoulders and make it the same color as the jacket so it doesn’t look like I’m wearing a military uniform.

Fit: I’m 5’11” and 175 lbs, wearing the size medium and it fits perfectly.
