Hello. I'm a newbie, but I've been a guest for years. Great site and contributors. My special interest is urban survival. sort of a"get me out of this building/tunnel and home "focus. My work and pleasure often take me into the city and into secure buidings. I hope to be a useful addition to the Forum. My first question is: does anyone have any experience with a product named the Survival Straw, sold by Brigade Quartermasters ? I've been relying on it in my briefcase kit, but without any field experience. Second inquiry: now that Evac-u8 hoods have been recalled, anyone have a reasonably priced and sized alternative?
