Berghaus GR20 Storm Waterproof Jacket | First Look

The GR20 Storm is the most breathable three-layer Gore-Tex jacket in the world

The progression of outdoor gear in the past few years has been monumental and Berghaus have just upped the ante again with the GR20 Storm Waterproof Jacket – the most breathable three-layer Gore-Tex jacket in the world.

The key attributes we look for in any top waterproof jacket are, of course, waterproofing and breathability (which translates pretty well as comfort, especially over long distances), as well as packability and weight.

“The GR20 Storm uses a combination of hyper breathable face fabric, new Gore-Tex Active shell membrane and Berghaus Body Mapped Storm Vents”

Berghaus know what matters and what doesn’t matter when you’re out in the wild. Their gear is made first and foremost for practicality. Every little design feature is there for a reason, to maximise the outdoor experience, and this is evident across their range.

Their Cape Wrath jacket would be a flagship bit of kit in plenty of other outdoor clothing ranges. It weighs just 345 grams, it’s built for convenience and it offers extreme protection from the rain and wind, nuisances which are all too familiar to the British adventurer. It’s a really reliable jacket.

The Berghaus Cape Wrath, back, and GR20 Storm jacket, front, both make for great mountain running jackets.

The fact that the GR20 Storm Jacket goes above and beyond the Cape Wrath’s build is no mean feat.

The pioneering GR20 Storm uses a combination of hyper breathable face fabric, new Gore-Tex Active shell membrane and Berghaus Body Mapped Storm Vents.

Body mapping is an intricate system which Berghaus have used here to ensure each vent is exactly where you need it to be. Vents allow heat and humidity to escape without allowing water back in, so you stay dry without overheating, and this combination is what makes the jacket so breathable. You’ve got large hand packets on there to expel the air as well.

On the run with the GR20 Storm jacket.

Basically, what this means is that you can wear this jacket for 30 minutes or 30 hours and the build of the kit will keep you comfortable and dry, which at the end of the day is (or should be!) exactly what you’re looking for from a high-quality waterproof. Heat can get out, but water can’t get in.

The jacket weights 277 grams (size medium), which for a three-layer Gore-Tex is impressive, and crucially it packs down super easily as well. It’s no trouble at all to pack up the GR20 Storm Jacket and stick it in your bag if you’ve got any doubts over the weather, and if it does stay dry and the jacket does stay in your pack, your back won’t have to deal with too much extra weight.

All of the above means the GR20 Storm Jacket is not only a great option for day hikes but a really strong piece of kit for trail running and climbing as well. It’s got the lightweight qualities, the breathability and crucially, the reliability.

Lightweight material, breathability and waterproofing give you everything you need to get out on the trails and protected from the elements.

It’s also got an adjustable hood that has a single point for adjustment. This isn’t only something that adds convenience, especially appreciated in extreme situations, it’s actually a crucial factor in giving the jacket that low weight number as well. The tailored hem of the jacket is purpose-built to be worn with a harness or backpack too, which is extra handy.

Berghaus’ MtnHaus Innovation Team test their kit in the mountains, where it’s going to be used, as well as putting it through all the abuse you’d expect in their controlled test centre.

They’re a trusted brand, and if you’re looking for top of the line, then look no further than Berghaus’ latest. The Cape Wrath is a hell of a coat, and the GR20 Storm is a jacket that could change the game.
