High on hype. Low on data.
Introducing......Futurelight - taddaaah!!!
Reading between the lines, it seems this latest miracle fabric works by using little holes which are small enough to prevent liquid water getting in but large enough to allow vapour to escape. Nothing new there...
So what's being brought to the party? Why, "Nanospinning" of course! Add it to your lexicon immediately, and make space for the inevitable TLA(s) to accompany it (plus, obviously, more bits of card added to the bunch strung to the zipper pull). Sounds like it's supposed to feel and behave like 'ordinary' fabric, and that the manufacturer can adjust the size of the holes, hence the novelty, but we're told little about its other properties (e.g. insulation, weight, durability, water retention etc). We are advised, however, that its "possibilities could be endless"! Yes, of course they could.
In the (unlikely) event of extended field testing by real people use proving it to be the game-changer it claims to be, I'll be happy to wait until its use becomes widespread, prices have steadied, and someone in AliExpressLand has worked out how to copy it.
Until that happy day, I'll just carry on using my "loud, crunchy, muggy and unpackable" waterproof garments - at least, that's how they're described by a certain Scott Mellin, Global General Manager at Mountain Sports at The North Face, (he must have a big one - business card, that is), who hasn't even seen them!
