The Best Ultralight Hiking and Running Jackets of 2024

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.

This article offers my expert tips on how to choose the best ultralight shell for your needs, followed by my freshly updated picks for the best models on the market today, based on real-world, backcountry field testing and more than 25 years of experience reviewing outdoor gear and apparel, including more than 10 years running this blog and previously the lead gear reviewer for Backpacker magazine for 10 years.

In other words, they are usually less than half the weight and bulk of a standard waterproof-breathable jacket. While a few may be partly or even fully waterproof, many are water-resistant and windproof, providing a minimum level of protection from the elements.

While these jackets, also known as ultralight wind shells, are marketed primarily to trail runners, they are often a better choice than a heavier, bulkier rain jacket for dayhikers, climbers, and lightweight/ultralight backpackers who don’t expect to encounter heavy rain. I’ve used many of the models reviewed here for lightweight dayhikes and some of the more durable models for backpacking and climbing when the forecast threatened no more than passing showers or thunderstorms.
