How To Choose The Best Lightweight Hiking Rain Jacket

Weight

Hiking rain jackets are usually made to be lightweight and packable. However, the weight of each product can still vary significantly depending on material and features.

Most hiking rain jackets have a weight between 10-15oz. The protection they offer without excess weight is impressive, although breathability can be an issue with some models.

Anyone looking to go ultralight will be able to find a jacket that weighs 10oz or less. Despite sometimes lacking the robust weather-resistance of a traditional hiking jacket, they are supremely lightweight.

The jackets on this list aim to balance weight saving with performance. Every product is designed with the capacity to keep you dry with minimum bulk.

Waterproofing

The level of weather-resistance offered can vary greatly between each jacket. Some will offer full ‘waterproofing’ that’s capable of withstanding torrential rain. Others are classified as ‘water-resistant’, meaning they are useful in light rain but not fully waterproof during a downpour.

Many of the lightest hiking rain jackets are rated as ‘water-resistant’. Despite being well-suited to anyone trying to save weight, their performance under extended water exposure is limited.

Once you slightly increase the weight, it’s possible to achieve full waterproofing. Many of these jackets use an outer membrane that is impermeable, with Gore-Tex being one of the most reliable options.

‘Fully taped seams’ is also a desirable rain jacket feature. It means they have placed waterproof taping along the interior seams to stop potential water leakage.

Durable Water Repellent (DWR)

Durable water repellent (commonly known as ‘DWR’) is an additional coating that is often applied to the outside of a rain jacket. It stops moisture from entering the exterior fabric by beading it into droplets.

DWR coatings are great at keeping you dry in light rain. It will keep the jacket material dry and reduce excess water weight that could otherwise have been absorbed.

It’s worth noting that DWR finish does not mean waterproof. ‘Waterproof’ and ‘water-resistant’ jackets can both be equipped with DWR, regardless of their ability to keep you dry.

Breathability

Anyone that plans on hiking in warm weather should prioritize breathability. It refers to the amount of moisture allowed to leave the jacket without water entering from outside.

Most modern rain jackets are relatively breathable, although some perform much better than others. Gore-Tex is commonly known as a market leader in waterproofing, but their jackets are also some of the most breathable around.

Some manufacturers are now making fabrics that can rival the ‘tried and trusted’ Gore-Tex. Materials such as ‘eVent’ are using technology that is adept at allowing perspiration to escape, with every brand offering an equivalent solution.

It’s worth noting that many ultralight jackets offer decent breathability thanks to the use of thinner materials. Paying the required premium for a quality product is usually the way forward if you want to guarantee comfort in all conditions.

Packing Size

Hikers are always concerned about packing size. Finding a reliable rain jacket compresses enough to save pack space can be invaluable on the trail.

The best lightweight hiking rain jackets are generally some of the most packable on the market. Weight is a great indicator of how small a jacket can compress or fold when not in use.

Some jackets are able to fit into their own pocket or hood, which can make them easy to manage. However, keep in mind that it’s not always a clear indicator of packing size.

Mobility

The last thing you need is to feel restricted when you’re hiking and scrambling. Many modern hiking rain jackets are designed to improve mobility and can give you enhanced freedom of movement.

The use of stretch fabric blends is starting to become common place amongst high-end hiking jackets. It allows the jacket to move with your body at all times and reduce any restriction.

More traditional lightweight rain jackets tend to use a slightly relaxed fit that will give your arms space to move. It is often the most suitable option for ‘weight conscious’ hikers looking to save a few ounces.

It’s worth noting that stretchy rain jackets will often cost significantly more than a standard shell. However, the outlay is often worth it if you’re hiking challenging trails.

Features

Pockets

Every hiking rain jacket will come with a different selection of pockets. Most substantial rain jackets come with hand pockets, while some ultralight options will forgo pockets altogether.

If you’re serious about saving weight, you will probably find that your new jacket only features a chest pocket. However, if you can afford an additional ounce, you will find a jacket with multiple pockets that can improve practicality.

Hoods

Anyone that’s been caught in a downpour will know the importance of a hood. Having a wet head is rarely fun, especially if you’re on a prolonged excursion.

The most important thing to assess here is adjustability. You need to make sure the hood conforms to your head when facing strong winds without blocking your vision.

Vents

Ventilation zips have become a popular feature of modern hiking jackets. It will allow you to release hot air quickly during an intense hike or in warm weather.

Pit zips, side zips and core vents are the most common options found. Each one of these offers unique benefits that can keep you cool, although they will usually add weight to your jacket.

Waist Adjustment

Almost every hiking rain jacket uses a cinch at the waist hem. It’s essential to keeping out water and can also improve overall fit and mobility.

The lightest hiking rain jackets usually come with a toggle cinch on one side, while heavier options will have a cinch on both sides. Either way, they are usually incredibly user friendly and their importance should not be underestimated.
