While I won't argue about the merit of these shelters at this point, my take on Golite is it fills a unique niche as a company.
Golite, at its size, is more of a gateway drug to ultra light, a good place for the masses to venture into the ultra light realm.
I know it was for me: I started with a Golite Down Vest, poncho, and Den 2 shelter (not a popular choice around here, but serves me well enough).
Starting as a NOLS trained heavy-pack hiker, companies like Gossamer Gear, Six Moon Designs, and Tarptent were too unfamiliar to me to start.
And even once Golite has 'em hooked, they have packs and sleeping bags/quilts that are still good for the more seasoned ultralighters.
All that being said, It would be nice if Golite had an equivalent to the Jam2 or Venture quilt in its shelter line to keep us crazies happy.
