The Best Hiking Waterproof Rain Pants of 2022

In a perfect world all hikes would be conducted in sunny dry weather, but rain and wind should not put you off from going on a hike as long as that’s safe. In rainy weather a pair of waterproof pants is a great addition to a rain jacket as it decreases the wind-chill effect and keeps your lower body dry. However, not all waterproof pants are suitable for hiking and other aerobic activities (trekking, mountaineering etc.). Waterproof pants for hiking should provide good breathability so that the moisture (perspiration) from the inside can pass through them to the outside. Otherwise, you might keep the rain out but anyway be soaked in your own sweat.

Therefore, modern waterproof pants are made of so-called waterproof/breathable fabrics (such as Gore-Tex and Pertex). These fabrics prevent rain drops from penetrating, but at the same time allow moisture to escape from inside to the outside. In addition to breathability, hiking waterproof pants should also be lightweight, functional and durable.

Here we selected and reviewed the best waterproof pants to make your buying decision a little easier. Note that all products in this review are normally worn over regular hiking pants – you only wear waterproof pants in case of rain or strong wind. If you want water-resistant pants to be worn directly on the skin, you should have a look at our selection of softshell pants.

1. Buying Waterproof Pants – What is important?

Weight and size:

Aerobic activities such as hiking, trekking and mountaineering require lightweight gear. Waterproof pants are usually light, but you can still eliminate some weight by wearing/carrying a pair of particularly lightweight rain pants. Read more about why it is important to use lightweight gear for hiking in our article Why hike lightweight. As waterproof pants are often carried in the backpack and only used in case of heavy rain, it is also important that they pack small. In this review of the best waterproof pants we only listed lightweight products which pack very small.

Material:

High-quality waterproof pants are made of materials that do not only provide protection against rain and wind but also breathability. However, it’s important to note that there is no such thing as a completely waterproof fabric that is also breathable; there is always a trade-off between water-resistance and breathability.

Nevertheless, some fabrics offer better breathability than others while maintaining a similar level of water-resistance. Popular waterproof/breathable fabrics are Gore-Tex, eVent and Pertex. Some outdoor clothing brands develop their own high-performance waterproof/breathable fabrics, like Mountain Hardwear (Dry.Q) and Marmot (MemBrain).

The level of water resistance is measured by the hydrostatic head while the “breathability” is measured by MVTR (Moisture Vapor Transmission Rate). Check out our article Rainwear: Hydrostatic Head and Breathability (MVTR) to learn more about these two parameters.

Waterproof fabrics differ by construction and waterproof technology.

Waterproof Technology:

There are two different waterproof technologies; laminates and coatings.

Laminates feature a membrane that prevents liquid water from passing through from the outside but at the same time allows vapor from the inside to pass through. These membranes are typically extremely thin (0.01 millimeters) and therefore they are sandwiched between two other layers for protection. They are usually made of polytetrafluoroethylene or polyurethane.

Coatings on the other hand are applied directly to the interior of a garment – a polyurethane layer is basically painted onto the interior of the fabric. As it is quite complicated to paint the polyurethane onto the fabric in an even layer, the polyurethane coat becomes relatively thick. The coating is made porous in the process of application by using an agent that creates tiny holes in it.

In general, coatings differ from laminates by breathability and price. They are significantly less breathable but on the other hand they are also less expensive. Other properties such as durability and water-resistance depend more on the actual garment than on the waterproof technology.

In this review of the best waterproof pants we listed both products that utilize laminates/membranes and a product that utilizes a coating.

Fabric Layers:

There are three different types of waterproof fabrics; 2-layer, 2.5-layer and 3-layer waterproof fabrics. Note that the layers are very thin and bonded together and thus you can’t see them with the naked eye.

2-layer fabrics consist of an outer layer with a coating or a membrane. 2.5-layer fabrics consist of a face fabric with a coating or a membrane and a non-fabric material on the inside (protective film). 3-layer fabrics consist of a face fabric, a membrane and a liner.

For more information about waterproof/breathable materials, check out the Hardshell section in our article Comparison of Shell Materials.

Regardless of fabric type, waterproof pants for hiking are always treated with DWR (Durable Water Repellent) on the surface, which will eventually be washed off with long-term wear and tear. You can, however, reapply DWR to re-waterproof them – read how here.

Seams:

Waterproof pants for hiking should be equipped with taped seams for maximum weather protection. All products in this review have taped seams. Learn more about taped seams in this blog post from Trespass.

Pockets and Zippers:

If you are caught out in a rainstorm in the blink of an eye, you will want to pull on your waterproof pants very fast. Therefore, it is a must that they are equipped with zippers from the ankle and up, so you don’t have to take your boots off when putting the waterproof pants on. Some waterproof pants have side zips which extends all the way up to the waist band. The side zips can also double as vents.

Pockets are not a must on waterproof pants, but they can be convenient for quick access to small essentials. If the pockets are zippered, they should be equipped with water-resistant zippers and/or storm flaps to prevent the rain from entering.
