I have a mountain hardware lamina torch 3 degree (its advertised as 0, but says 3 on the tag). Its synyhetic, has a center zip and a baffle that makes it very warm. Ive used it twice in the 4 or 5 hears i have had it. its a little bulky by todays standars, but for a basecamp application it would be fine. Id ask 125 shipped.
