Marmot Minimalist Pants

Marmot Men's Minimalist Lightweight Waterproof Pant, GORE-TEX with PACLITE Technology

Marmot’s Minimalist Pants are one of the toughest, most packable, most waterproof, and most affordable high-performing hiking pants in the business.

Given the wealth of worthy competition out there, that’s one heck of a lofty claim, we know.

So what is it that led us to hand the Minimalist the title of best rain pants for hiking & backpacking?

Let’s start with that all-important core competence: waterproofing

Boasting a durable, tear-resistant, 2.5 layer construction that includes a Gore-Tex Paclite membrane and DWR coating, the Minimalist have their bottom line covered with room to spare. 

And with taped seams and water-resistant zippers sealing off the most frequent leak-points, it’s easy to understand why these are Marmot’s most popular bad-weather hiking pants.

As the name implies, the Minimalist don’t offer much in the way of fancy features. While that may seem like a criticism, it’s not. By leaving out the optional bells and whistles, Marmot have been able to keep the weight of the Minimalist to—you guessed it—a bare minimum.

Weighing in a mere 11 ounces, these aren’t the lightest pants on our list but also far from the heaviest. And given the protection and fuss-free functionality you get in return, the extra ounce or two of additional weight compared to ultralight alternatives is a small price to pay.

Bottom line: Hard-wearing, lightweight, packable, and about as water-resistant and breathable as they come, the Marmot Minimalist are ideal for any adventurer who prioritizes practicality and performance over frills.

Outdoor Research Helium Pants

Outdoor Research Men's Helium Pants - Lightweight Waterproof Rain Gear

The Outdoor Research Helium Pants are ideal for campers and hikers who like to keep weight to an absolute minimum. 

Tipping the scales at a mere 6.5 ounces, these are among the lightest pairs of mens waterproof pants on the market. They also pack down to a tiny, pack-space-friendly bundle and could even be stored, in a pinch, in a jacket pocket.

But it ain’t all about weight and pack size…

In terms of waterproofing, breathability, durability, body-heat management, and comfort, the Helium outperform all but a few of their heavyweight peers. 

These rain pants are made with 30-denier, ripstop, 2.5-layer Pertex Shield+. With a hydrostatic head rating of 13,000mm and a moisture vapor transmission rate of 20,000, they’re more than well enough equipped to keep you dry in heavy downpours whilst also ensuring things don’t get too sticky on the inside when you’re working up a sweat. 

Other nice touches in the Helium include articulated knees and slightly gusseted crotch that provide greater freedom of movement, an elastic waist for enhanced comfort, and fully taped seams.

Bottom line: Lightweight, packable, and just about as waterproof-breathable as they come, these tiny but tough rain pants are the perfect pick for gram-counting minimalists, high-intensity athletes, and rain-averse aquaphobes alike.

Columbia Rebel Roamer

Columbia Men's Rebel Roamer Pant x Inseam

Columbia’s Rebel Roamer pants are the ideal pick for occasional hikers looking for a pair of reliable, heavy-duty rain pants that won’t deal too big a blow to the old bank balance.

Made with tough, 70D nylon and using Columbia’s Omni-Tech waterproof-breathable fabrics, the RR offer above-average weather protection and breathability while throwing in absolutely oodles of durability.

Given the above and the pants’ low price, you might ask, why aren’t we all kitted out in the Rebel Roamer when we head for our wet-weather wanders in the wilds? 

Well, there are a few downsides. While these pants tick the rain-resistance and ruggedness boxes surprisingly well given their friendly price tag, they leave quite a lot to be desired in the way of convenience-enhancing features. 

The most notable absence is found in the lack of side zippers and pockets.

This may not seem so egregious an oversight if you’re carrying them as a just-in-case fallback for foul weather, granted. However, it does mean you’ll have to take your boots off to get them on, are missing two fairly fundamental ventilation points, and will have nowhere to stuff your map/phone/hands if your jacket pockets are already occupied. 

Bottom line: A tough, reliable, low-cost rain pant that lacks a few high-end features but covers the basics very well. Frill-free but perfectly functional, the RR are probably the best waterproof pant you’re ever likely to come across at this price point.

Benefits & Features of Hiking Rain Pants

What To Look For In Rain Pants for Hiking and Backpacking?

The key feature every camper needs to look for in rain trousers is waterproofing. It doesn’t matter whether you’re a casual or serious hiker; high-quality waterproofing technology is the first thing you look into.

After you’ve ensured that the product has a good waterproofing technology, other major considerations include breathability, durability, affordability, and weight. These secondary features will, of course, change in order of importance depending on your the needs for your hiking or backpacking rain gear.

Waterproofing Versus Water-Resistance: Is There A Difference?

Many people use the terms waterproof and water-resistant interchangeably. It’s important, however, to draw a distinction between these products because they offer customers different degrees of weather protection.

Simply put, water-resistant pants are not as strong as waterproof ones. Only invest in water-resistant trousers if you plan to go to areas where there isn’t a great deal of heavy rain. 

What Are Waterproof Ratings?

Over the years manufacturers have devised a standardized ranking system measured in millimeters that lets consumers know how well waterproof products wick off moisture. A product can’t be considered water-resistant until it reaches 1,500mm.

Standard Waterproof Rating Ranges

As mentioned above, any product that measures 1,500mm or slightly below is merely considered water-resistant. You’ll only get good weather protection from water-resistant products in areas with a light drizzle.

The first official waterproof ranking is between 1,500mm and 5,000mm. This low-end range is best for protection against light rainfall. Even casual campers should strive to get a product that falls between these ranges for decent protection. 

Mid-range waterproof rain pants measure between 5,000mm and 10,000mm. These are good for hikers expecting moderately heavy rainfall on their trek. They might not be able to keep out moisture from torrential downpours, but they offer the best mix of lightweight construction and weather protection. 

The highest waterproof ratings top out over 10,000mm. Serious hikers who often travel into hazardous weather conditions should look for a product with these specs.

What’s The Hydrostatic Head Test?

To test any rainproof product, manufacturers take a piece of fabric and put it underneath a cylindrical container of water. Scientists then record the amount of water in milliliters they can pour into the container before water starts leaking through.

The minimum amount of water required to leak through a piece of waterproof fabric is known as the hydrostatic head (sometimes abbreviated as HH). Hence, manufacturers call this standard waterproof screening the Hydrostatic Head Test.

The Pros & Cons Of Waterproof Membranes Versus Water-Resistant Coatings

There are two major distinctions in the world of waterproof vs water resistant design: membrane inserts and waterproof coatings. While membrane products are stronger than those with water-resistant coatings, there are advantages and disadvantages to investing in either of these constructions.

Waterproof Membrane: Durability Over Compressibility

In addition to keeping rain out, membranes are designed to effectively vent for sweat and body oils. Manufacturers do this by tightly bonding a thin waterproof membrane to the pants’ face fabric. The internal membrane usually has billions of tiny pores that are too small for rain to penetrate, yet large enough to let internal condensation out.

The greater breathability and durability membrane products offer make them the preferred choices for serious hikers. Name-brand membrane products like Gore-Tex hiking pants, however, tend to cost and weigh more than less advanced waterproof coated trousers.

While Gore-Tex is a prominent name in the industry, many people mistakenly refer to all membrane constructions as “Gore-Tex.” There are, however, many other big names in the membrane manufacturing industry such as eVent and MemBrain Strata.

Lightweight Waterproof Coating

Waterproof microporous coatings are only designed to keep water from penetrating the fabric; they aren’t designed to let sweat out. For this reason, you can often get an accumulation of sweat on the inside of the material. On the plus side, products with waterproof coatings are easier to pack and more affordable than membrane products.

The coating often used is called Durable Water Repellent (aka DWR). DWR fabrics are essentially a thin chemical layer that use fluorocarbons or fluoropolymers to effectively wick off moisture on the trousers’ outer layer. Whether it’s on a raincoat or waterproof pants, DWR’s main purpose is to stop water from clumping on your fabric (DWR products require occasional reapplication with a DWR detergent).

Importance Of Taped Seam Construction

Even if your product has the highest-quality waterproof membrane, you won’t get the full benefits of rain-protection unless it’s made with taped seams. These heat-sealed seams are an essential design feature because they help keep water from trickling through your materials’ stitching. Ensuring the product has a seam construction is critical if you’re a serious hiker going to areas with a lot of rain.

Common Layering Of Membrane Pants

Most are made with one of these three fabric layers: 2, 2.5, and 3. Although they will often appear to only have one layer when you hold them in your hands, manufacturers bind these fabrics so tightly that you won’t be able to notice them. Usually these inner fabrics have a special construction that’s able to capture sweat, oils, and moisture, thus increasing breathability without sacrificing warmth retention.

What Layering Design Is Best For Casual Hikers?

2 and 2.5-layer products are made with a waterproof exterior fabric and an internal membrane. Usually the inner lining of 2-layer products is made with some combination of polyester and mesh fabric. In the case of 2.5-layer trousers, manufacturers use a thin layer of polyurethane laminate to provide extra breathability and moisture-protection. 2-layer products are ideal for casual campers who expect to face moderate rainfall on their hikes.

On the other hand, 3-layer waterproof pants usually have a stronger polyurethane film inside them. Although 3-layer garments are made with an outer waterproof fabric, an internal membrane, and another internal bonded lining, these three fabrics are woven so tightly together that they can feel like one layer. Three-layer products are best suited for serious hikers who expect to face torrential downpours.  

Obviously, 3-layers are more durable and long-lasting, but they are also heavier than the 2.5 and 2-layer options. Casual hikers who expect to experience light to moderate rainfall will prefer 2.5 and 2-layer fabrics because they are lightweight and easier to pack.

Breathable Rain Trousers?

After considering how much protection you need from rain, it’s time to look at how well they should let internal moisture out. If there’s no way for sweat and body oils to escape from your clothing when hiking in rain pants, then expect to deal with soggy legs on your hike.

However, breathability isn’t just about comfort. Besides being uncomfortable, sweaty legs can sap your energy and significantly reduce the quality of your hike. This is a serious concern if you’re someone who often goes on arduous hikes. 

Rain products with a breathable fabric usually offer the most comfort for campers seeking to avoid the sticky feeling of sweat-drenched legs. There are, however, many weatherproof coated products that have long side zippers you can use to manually vent (and a few with full length leg zips).

How Is Durability Measured?

For most hikers, durability shouldn’t be as big a concern as water-resistance and breathability. Durable products obviously have the benefits of increased longevity and strength, but they tend to be heavier and more difficult to pack. Only prioritize durability if you’re a serious hiker who expects to put your apparal to the test often on challenging hikes. 

You’ll often see denier (abbreviated “D”) used when describing fabric type and durability. A denier refers to the density of fabric per length and weight of the garments’ fibers. One denier is measured as a single strand of fabric, so higher denier numbers mean each strand of fabric has a greater diameter.

Extra Features To Look Out For In Waterproof Gear

Whenever you see “additional features” you should instantly think “additional weight.” The only extra features worth your time are side pockets and side-zippers. Beyond these two considerations, any other additional features will only add unnecessary weight to your backpack. 

Convenience of Side Pockets

Side pockets are a handy feature for keeping your hands warm on cool nights and storing a few handy items for quick access. Often rain trousers have either a pair of side pockets or a back pocket in their design. Sometimes these pockets double as a stuff sack, which makes packing them up in the wild a great deal easier. 

When examining pockets, be sure to look into whether they are made out of a breathable material. It’s also important to consider if these pockets have a zippered construction and whether that zipper is waterproof.

The Benefits Of Side Zippers

Garments with waterproof zippers on the sides are easier to pull over your boots while on the go. In addition to the ease of pulling zippered pants on and off, ones with side zippers allow you to quickly vent off if your legs feel stuffy.

One thing to look out for when examining zippered products is how far the zipper goes up. The shortest length a side zipper will go is usually a quarter length of the your pant leg. There are a few zippered options that go up to the knee and some run the whole length of the leg.

What’s The Ideal Weight For Hiking Rain Pants?

No matter what camping item you’re researching, weight will always be a concern. Even if you’re an ultra light camper, however, you need to prioritize the quality of waterproof protection over weight.

Don’t just go hunting for the lightest waterproof breathable pants. The main point of buying them, after all, is to protect you from the rain. 

For reference, the median weight tends to be between ten and eleven ounces.

Next up, we’ll review the best waterproof hiking pants…
