Inspired by Ray Jardine, this backpacking supplier makes commercial versions of his ultralight designs for tarps, backpacks, sleeping bags, etc. and now is prospering from equipping the various “Eco-challenge” type racers plus lazy people like me. Though I had no use for the Jardine approach to sleeping bags (top layer only; I’m happier with a North Face Cat’s Meow), all the other products I’ve tried (see below) have been exceptional.
[The only product Stewart recommended in 2003, which is still available, is the umbrella. Needless to say, GoLite stocks newer -- presumably improved -- versions. If you have any experience with other products from GoLite, please let us know. ]
