Membrane paradigms in cycling gear, always a hot topic, aren't they? I can see why you're skeptical, especially when it comes to marketing hype. But let's not throw the baby out with the bathwater here. Yes, some of these membranes might be overpriced gimmicks, but that doesn't mean they're all useless.
Take Gore-Tex, for example. It's not perfect, but it does a decent job of keeping the rain out while still allowing some breathability. And sure, it might not be worth the premium price tag, but for serious cyclists who ride in all weather conditions, it could be a worthwhile investment.
Now, I'm not saying we should blindly believe the marketing claims. As you rightly pointed out, there's often a lack of scientific studies to back them up. But that's where real-world testing comes in. If a membrane keeps you dry and comfortable on a wet and miserable ride, then it's done its job, hype or no hype.
And let's not forget the simple solutions. Sometimes a good old-fashioned waterproof jacket is all you need. No fancy membranes required. But for those times when you need a little extra protection, it's worth exploring the options.
So before we dismiss membrane paradigms as a mere marketing ploy, let's consider the benefits they can offer. And let's keep pushing for more scientific research to back up the claims. After all, as cyclists, we deserve gear that performs as well as we do.
