The Black Diamond Distance Wind Shell.

The Best Ultralight Hiking and Running Jackets of 2025

By Michael Lanza

You’re out on an all-day hike or a long climb or trail run or ride in the mountains. The weather forecast looked pretty good before you set out—but no one shared that memo with the wind that just started hammering your summit ridge, or the spitting rain and hail now pelting you as you contemplate the sudden drop in temperature and the miles between you and shelter. The question now is: What’s in your pack?

If you’re smart, it’s an ultralight jacket that takes up little space, but is about to gift you with just the right amount of weather protection when you need it.

Two startingly loud, sharp, and sustained crackles of thunder and a flash of lightning gave us about a two-minute warning before the skies opened up while we hiked at well over 11,000 feet on the Continental Divide Trail in Colorado’s San Juan Mountains in mid-September. I got Rab’s Downpour Light Waterproof Jacket on and zipped up moments before the thunderhead began bombarding us with wind-driven rain and hail. And this ultralight rain shell kept me dry hiking through that storm and setting up our tent in steady rain and wind once we found a campsite.

We ask a lot of ultralight wind shells, these wispy jackets that often weigh no more (and sometimes less) than your hiking shorts. We want them to breathe well when we’re hiking or running uphill while, of course, blocking the wind effectively—and not feel like a kitchen trash bag with sleeves and a hood. On trail runs, dayhikes, and a backpacking trip from the desert Southwest in spring to the mountains of Southwest Idaho, in a wide range of fall and spring weather that challenges any outer layer to keep you comfortable, I found that OR’s Shadow Wind Hoodie did just that, quite well.

On winter and spring trail runs in my local foothills in every combination of cool to cold wind or calm air and overcast to sunny skies, and on a hike-scramble of 11,330-foot Twin Peaks in Utah’s Wasatch Range—nearly nine miles with 6,200 vertical feet of up and down—on a sunny October day with temps ranging from the 40s to the 50s Fahrenheit and cool wind at times, the Arc’teryx Norvan Windshell Jacket demonstrated its strengths and minor shortcomings as one of the very lightest of the many ultralight wind shells you’ll find today.

After sweating hard on a sunny and humid June morning hiking up the headwall of Huntington Ravine—the steepest and hardest trail on Mount Washington—we hit the cool wind blowing across the mountain’s alpine terrain. I pulled on my Kor Airshell Hoody and it tamed that wind while breathing so well that the wet sun shirt against my skin dried out quickly. And that pattern of sweating and hitting wind kept repeating itself on that two-day, 21-mile hut trek in New Hampshire’s Presidential Range, providing plenty of opportunities for the Kor to show off its strengths.
