I’ve got the 7 Mesh Oro jacket for road riding, which uses the Gore shake-dry material. It’s absolutely fantastic. It was given a baptism of fire when I first used it for the Etape Eryri Xtrem this year – 13 hours of torrential rain, ridiculous winds, and varying temperature – it kept me dry and at a comfortable temperature for the duration. Excellent breathability, packs down to next to nothing, easy to take care of, no reproofing required. I couldn’t ask for anything more from a road jacket. However, the material is way too fragile for mountain biking and I believe that it’s recommended you don’t wear a pack with them. I can see the material getting easily torn by a stray branch or bramble, yet alone a crash. I’m firmly in the camp of different jackets for different disciplines – it’s the only way to avoid compromise (well, apart from the compromise of extra cost).
