The featherweight stats have been achieved not just by removing the outer fabric, but also by trimming down on the feature set and taking a minimalist approach. There’s a slim-fitting hood with an elasticated rim, a full main zip, elasticated cuffs and then zipped handpockets – one of which doubles as a stuff sack for the jacket itself. When you’ve packed it all away, the result is a minuscule little bundle the size of a fist.

OK so you have something that’s light, waterproof, and remarkably breathable also, but there’s a catch, and that’s that the Gore R7 isn’t particularly durable.

This isn’t the kind of jacket to wear with a backpack, the risk here being that the straps and back panel will ultimately rub away and compromise the longevity of the membrane in these areas. It’s the same problem that Gore-Tex Active has, or any other jacket with an extremely lightweight membrane. So this ultimately discounts it as something to use for hikes and runs of more than a few miles, or for climbing or scrambling, but for those quick evening runs, or for cycling, it’s perfect.

As things currently stand, for such a level of breathability, protection and low weight, there’s inevitably going to be a trade-off in one area unfortunately. That being said, developments are certainly being made – The North Face’s Futurelight is certainly one to watch here.

Tester’s Verdict

Nic Hardy, Munro bagger

“I wore this in the Brecon Beacons while it was bucketing down and it was very impressive. You could see the moisture constantly beading right off it. It was also noticeably very breathable and without any issues on that front. The hood design is useful as it can be cinched in to really hold to, and cover, your face. I’d say this is ideal as an option to carry in summer, just in case there’s a shower, and then to wear right through winter during evening runs when the weather is a bit miserable.”

Trade Secrets

Thomas Weiss – Gore Product Manager

“We set our sights on creating the ultimate ultralight rain jacket that was still versatile and durable enough to withstand wet adventures. That is why we’ve chosen our revolutionary and extremely breathable GORE-TEX SHAKEDRY™ technology to prevent chilling effects and make packing away easy and pleasant – while keeping the design clean and puristic with a few smart features.”
