Quick Recommendations

How to Choose the Best Lightweight Rain Jackets for Backpacking

Let’s break down exactly what you should look for in a rain jacket to help you make the best choice.

Weight: How Much Is Too Much?

When carrying everything on your back for days, you want a jacket that doesn’t feel like a burden. Ultralight jackets can weigh as little as 6-7 oz, making them barely noticeable in your pack. If you can, a few extra ounces for added durability or features like pit zips.

Waterproofing: Will It Keep You Dry When the Skies Open Up?

Not all rain jackets perform equally in terms of waterproofing, so this is where you want to pay close attention. If you expect to face serious rain on your trip, prefer Gore-Tex jackets. On the other hand, jackets with proprietary waterproofing can give you solid protection at a more affordable price. Consider your usual backpacking weather. 

Breathability: Will You Stay Cool While Hiking?

There’s nothing worse than hiking in a rain jacket that turns into a personal sauna. However, the best moisture-wicking hiking shirts help move sweat away from your skin. If you tend to sweat while on the move, especially with a backpack pressing against your back, breathability is going to be a big deal.

Even the most breathable rain jacket can’t prevent dehydration during strenuous hikes. Following proper hydration strategies while hiking is equally important for maintaining energy and avoiding heat-related fatigue.

Durability: Will Your Jacket Survive the Long Haul?

Backpacking means a lot of wear and tear, whether it’s from brushing up against trees or stuffing your jacket in and out of your pack. For navigating rugged terrain, you might want something more durable, made from tough 100% recycled nylon ripstop. Lighter jackets are fantastic for reducing weight but may not hold up as well under rough use.

Packability: Does It Disappear Into Your Pack?

When the rain stops and the sun comes out, you don’t want your jacket hogging space in your pack. Look for jackets that pack down small, ideally into their pocket or a stuff sack.

Fit and Comfort: Will It Work with Your Backpack?

Here’s something a lot of people overlook—how does the jacket fit when you’re wearing a backpack? You want something comfortable under your pack straps and won’t bunch up or chafe. Adjustable features like cuffs, hem cinches, and hoods help keep rain out without compromising comfort. Stretch fabrics allow better mobility and won’t restrict movement while wearing a pack.

Your rain jacket isn’t the only piece of gear that affects comfort in wet weather. Wearing merino wool hiking socks helps regulate temperature, reduces blisters, and keeps your feet comfortable even when trail conditions become damp.
