You are very diplomatic, and I was not.
But still, do not quite agree.
The Integral Designs eVent jackets have been out for a number of years in the 10-12 ounce range. If we run out to buy newer gear that is much hyped, but no lighter or more breathable, all we are going to see is more hype, and will we really have anything better for more money spent?
I happen to like the Specter, because I got one on sale for $99 and it meets my every backpacking need. You are right, it was discontinued. First, it was replaced with a lighter model with a wispy WPB fabric and more features, and that was not popular, so it was dropped. The wispy fabrics were popular in several brands, but only for a while - not sure why. It may be because these fabrics were less, not more breathable than the eVent and newer Goretex offerings, and when in a heavy cold downpour, they are so thin that it feels as if they are totally sopped even if they are not.
A principal goal on this site is, it seems from the title, to lower pack weight. If I have something old that works AOK at a half pound, shouldn't I expect from the industry something better for that weight? Will we see anything better if we buy whatever is pushed out with much hype, but no real improvement? And you don't need to be a long distance trekker to appreciate an under half pound functional rain shell that will be a boon for runners, day-hikers, bicyclists, kayakers, etc. Many of us do these other activities too, sometimes in conjunction with trekking, and whatever we're doing in the outdoors, we will still probably want to take along a reliable, functional shell, and the lighter and easier it is to carry, the better.
It may not be playing nice, but if we don't demand something better, we won't get it.
Instead, just more and more of the endless marketing hype.
