Finding ultralight down jackets for big & tall hikers is a challenge. We review 6 top options that offer a true-to-size fit and excellent warmth-to-weight.
The sun dips below the ridge, and the temperature plummets with it, a familiar story in the high country. You reach for your puffy jacket, the one piece of gear that stands between you and a miserably cold evening at camp. But as you pull it on, the sleeves ride up your forearms and the hem barely covers your belt, leaving a chilly gap for the wind to attack.

The Challenge of Ultralight Down for Big & Tall
Finding ultralight gear can be a challenge for any backpacker, but for those of us in the big and tall category, it often feels impossible. The ultralight industry has historically catered to smaller frames, with "Large" or "XL" sizes that are often just wider, not longer. This leaves taller hikers with jackets that have inadequate sleeve length and torsos that are comically short, exposing wrists and lower backs to the cold.
The problem is one of proportions. A proper fit isn’t just about comfort; it’s about thermal efficiency. Gaps at the wrists, waist, or neck are avenues for precious body heat to escape. A jacket that’s too tight in the shoulders or chest compresses the down insulation, creating cold spots and rendering that high-tech fill useless. For big and tall hikers, the search isn’t just for a jacket that’s lightweight—it’s for one that provides complete, uncompromised coverage without weighing a ton.
Feathered Friends Eos: Custom Sizing for UL Fit
When you need a no-compromise solution from one of the most respected names in down gear, Feathered Friends is where you look. The Eos jacket is a benchmark for ultralight warmth, packed with high-quality 900+ fill power goose down. While their standard sizing is already quite good, their true value for bigger hikers lies in their Seattle-based manufacturing and willingness to do custom alterations.
For a reasonable fee, you can work with them to add length to the sleeves or torso of a new jacket. This isn’t just an afterthought; it’s a core part of their service. This allows you to get a truly dialed-in fit on a premium, ethically-sourced down jacket that will last for years of adventures. It’s an investment, but for a piece of gear this critical, having it made to your body’s specifications is a game-changer for staying warm from the Sierra Nevada to the White Mountains.
Enlightened Equipment Torrid: Custom-Built Warmth
Imagine a jacket built to your exact sleeve and torso length, with your choice of colors, and arriving at a shockingly low weight. That’s the promise of Enlightened Equipment, a leader in the cottage gear industry. Their Torrid APEX jacket uses synthetic Climashield™ APEX insulation, which offers fantastic performance in damp conditions—a huge plus for trips in the Pacific Northwest or humid Appalachian summers where down can struggle.
The real magic is in their customization menu. You can add inches to the sleeves and body length independently, ensuring you get the coverage you need without a baggy, inefficient fit elsewhere. This level of personalization is rare and makes the Torrid a top contender for any big and tall backpacker who has been frustrated by off-the-rack options. It’s a chance to build the exact midlayer you need, whether for a weekend trip or a full thru-hike.
Outdoor Research Helium Down for Storm-Ready Layers
Sometimes, your biggest concern isn’t just cold, but cold combined with wind and moisture. The Outdoor Research Helium Down Hoodie is built for these exact scenarios. It uses a Pertex® Diamond Fuse shell fabric that is impressively durable and weather-resistant for its weight, and it’s available in sizes up to 3XL, which often provides the necessary room for broader shoulders and chests.
While OR doesn’t offer specific "Tall" sizing, their athletic cut is often more generous in the shoulders and length than many competing ultralight brands. This makes it a great off-the-rack option to try first, especially for those who prioritize storm-worthiness. The key is to check their size chart carefully against your measurements. For shoulder season trips where you might encounter sleet or wet snow, the added protection of the Helium can be worth a few extra ounces.
Eddie Bauer MicroTherm 2.0: Accessible Tall Sizing
For many hikers, the world of cottage-industry gear and custom orders can be intimidating and expensive. Eddie Bauer’s MicroTherm 2.0 Down Jacket is a fantastic, accessible alternative that offers dedicated "Tall" sizing (LT, XLT, XXLT). This is a huge advantage, as these sizes are specifically designed with longer torsos and sleeves, not just more width.
The MicroTherm isn’t the absolute lightest jacket on this list, but it hits a sweet spot of weight, warmth, and value. The 800-fill-power down is high quality, and the jacket is frequently on sale, making it an excellent entry point for big and tall backpackers building their first ultralight kit. It’s a reliable workhorse you can trust for three-season trips, from chilly desert nights to crisp autumn mornings in New England.
Montbell Plasma 1000: Premium Japanese Fit
For the ultralight purist focused on maximum warmth for minimum weight, the Montbell Plasma 1000 Alpine Down Parka is in a class of its own. Using ridiculously lofty 1000-fill-power down and a gossamer-thin 7-denier shell fabric, this jacket is astoundingly light and compressible. It represents the pinnacle of minimalist design.
A crucial consideration here is the "Japanese fit." While often slimmer, Montbell’s sizing (available in U.S. XXL) can be surprisingly accommodating in length for some body types. It’s absolutely essential to consult their detailed measurement chart. For the tall hiker with a leaner build who has been swimming in the width of standard American XL sizes, the Plasma 1000 might just be the perfect, featherlight solution.
Goosefeet Gear Custom Jacket: Built to Your Specs
If you’ve exhausted all other options and are ready for a truly bespoke piece of equipment, Goosefeet Gear is the answer. This is not an off-the-rack product; it’s a collaborative process. You provide your exact measurements, choose your fabric, select the down fill power and amount, and decide on every feature, from the zipper to the pockets to the hood design.
This is the ultimate solution for the hard-to-fit hiker. Whether you have an exceptionally long torso, broad shoulders, or long arms, you can have a jacket built to your body’s unique blueprint. The result is a perfectly efficient, incredibly lightweight down jacket with no compromises in fit or warmth. It’s the pinnacle of ultralight customization for those who need a perfect fit to stay safe and comfortable in the backcountry.
Key Fit Considerations for Big & Tall Ultralighters
Finding the right jacket goes beyond just reading reviews; it requires knowing your own dimensions. Before you buy, grab a soft measuring tape and get some hard data. This will empower you to read size charts like a pro and make a smart purchase, especially when ordering from a cottage vendor online.
Focus on these critical measurements:
- Sleeve Length: Measure from the center back of your neck, over your shoulder, and down to your wrist bone. A good jacket’s sleeve will end here or slightly beyond.
- Torso Length: Measure from the base of the back of your neck down to where you want the jacket’s hem to sit. You want it to cover your waistband and the top of your pants even when you raise your arms.
- Chest Circumference: Measure around the fullest part of your chest. You need enough room to fit a base layer and maybe a light fleece underneath without compressing the down.
- Shoulder Width: Measure from shoulder point to shoulder point across your back. A jacket that’s too tight here will restrict movement and create cold spots.
Your goal is a fit that is close but not tight. You want to trap a layer of warm air without having baggy, empty spaces that your body has to heat. Compare your numbers to the manufacturer’s chart, and when in doubt, don’t be afraid to email the company—especially the smaller cottage brands—with your measurements to ask for their recommendation.
Remember, the goal isn’t to own the lightest gear, but to have gear that enables your adventures. A well-fitting jacket that keeps you warm and safe is worth far more on a cold mountain pass than a few grams saved. Get the gear that works for your body, and get outside.
