Waterproof Buying Guide

Whether you're taking to the trails, hitting the crag or venturing high into the mountains, a waterproof jacket is a year-round essential for any adventure. Here's our guide to all the tech you might come across to help you choose the right one for you.

What is a waterproof jacket for?

The answer may seem obvious, and it's true that the main function of a waterproof jacket is to keep you dry - but it should also do more than that. Your jacket should also be breathable, allowing sweat vapour to escape so you stay dry from the inside, and should help you to regulate your temperature and stay comfortable throughout your adventure.

What do you need your jacket for?

Many waterproof jackets are designed with a particular activity in mind.

 

Some are made for high-intensity activities like running or cycling. These make breathability their main feature; helping to keep you comfortable by allowing all the extra heat to escape.

 

Others balance durability, waterproofness and breathability, and are for sports such as mountaineering or ski touring. These use hardwearing waterproof fabrics that may feel stiffer on the body but can stand up to the demands of the mountains, such as abrasive rocks or carrying a heavy rucksack.

 

Most people, however, are usually looking for a jacket that provides everyday protection and sits between these two extremes. The selection of these jackets is much wider, covering a range of brands, prices, fits and colours, with some lighter in weight and others stronger depending on your preference.

Waterproof construction

Waterproof fabrics have different constructions, which are denoted as “layers”. Waterproof jackets are often 2-layer, 2.5-layer or 3-layer.

2-layer

A 2-layer waterproof is the most basic construction, featuring an outer “face” fabric with a waterproof membrane bonded to it. An additional lining is usually added to protect this fragile inner layer, which is usually made from nylon mesh, but not bonded to the waterproofing itself. Not many technical waterproofs will have a 2-layer construction.

2.5-layer

As in 2-layer jackets, 2.5-layer waterproofs feature an outer fabric bonded to a waterproof membrane. But, instead of a mesh layer to protect the waterproofing, a coating or print is applied to it, which is far better at protecting the waterproof layer and offers extra weather protection, too. These jackets are often lighter and more packable than 3-layer construction, but aren’t as durable and are less suited to mountain environments, so choose one of these if you’re after an everyday, packable waterproof to wear on the trails and keep in your pack for if the weather turns.

3-layer

In a 3-layer construction, the waterproof technology is sandwiched between face fabric and an inner fabric, usually woven or knitted. These jackets can be heavy and are less packable than 2.5-layer jackets, but are extra durable and suited to mountain conditions. If you’re looking for one waterproof jacket to do everything, go for a 3-layer.

Does it have to be Gore-Tex®?

GORE-TEX® is one of the best-known waterproof membrane technologies, and is the choice of many brands thanks to its durability and reliability. However, some brands are so confident in alternatives that they choose not to use GORE-TEX® at all, whilst others choose to use it in some items and use their own membranes in others. We recommend considering the other features of the jackets first if you're choosing between a GORE-TEX® jacket and a non-GORE-TEX® one, then consider whether the type of techology will make a difference to your adventures.

What features should I look for?

A comfortable fit

How a jacket should fit is entirely subjective: you should simply choose the one you are comfortable wearing. Some like a jacket long enough to cover the waistband, whereas others prefer it short and tailored. However, if you’re buying a jacket for a specific activity, there are a few things to consider when trying on. With climbing, for example, are the pockets high enough to be clear of your harness, or can you still see your feet? Or if you want it for running, is it tailored enough to sit close to the body and reduce drag?

 

More general considerations include: do the sleeves cover your wrists as you move your arms around? Is the material too tight across the shoulders and underarms? Remember, you may wear the jacket in a range of temperatures, so think carefully about the number of layers underneath and choose the fit accordingly.

Zips

To keep water out, some jackets use what is called a hydro-seal zip: a rubber mechanism that binds shut when closed. Others use a storm baffle, which is a piece of material that folds over the zip. Both methods are effective; a hydro-seal zip is lighter and less bulky, while a storm baffle tends to be more durable.

 

Some jackets also have pit-zips, which follow the underarms and can be opened if you get too hot. All jackets should be breathable, but this addition is great for comfort if you know you are prone to overheating. 

The hood

A hood’s function is simple: protect your head and face from the elements. A well-designed hood can make even the heaviest rainstorm feel like a light shower.

 

Some hoods feature a wire peak, which enables you to ‘customise’ the fit and shape of your hood. Other jackets have larger hoods to accommodate a helmet, which is useful if you plan to wear your jacket for climbing or cycling.

 

When putting the hood up, make sure it firmly fastens around your head and face without obstructing your vision; that the peak forms a protective shield for your eyes; and that it is easy to turn your head without limiting your movements.

Pull cords and Velcro

Waterproof jackets should have good quality draw cord or Velcro seals at the head and wrists, to effectively keep water out. Velcro tabs should be easily accessed and sealed, and elastic pull-cords should be intuitively placed.
