This is the Permanently Waterproof Breathable (PWPB) jacket from Gore that’s rated as durable enough for hiking with a pack.
Considering that this is potentially game-changing DWR-free technology, the launch has been surprisingly low-key and reviews are very sparse – all I could find is this in Spanish:Â https://www.youtube.com/watch?v=WLfPChMRfug. I’m not much of a linguist, but he seemed to like it. For some reason Gore are being coy about the weight, but the review suggests it’s a bit over 200 grams / 7oz which seems acceptable if it really is as durable as advertised.
The launch price was a daunting $400 but it’s been out for a few months now and you can pick it up at a significant discount. So I’m wondering if anyone has practical experience with the garment? Any feedback would be much appreciated, particularly comparisons with the Columbia PWPB offerings.
