Thats not something I was told Tom - That was my first-hand experience - I have both versions. Two similar labels but one (on the REI tent), very distinctly states that 'it IS made with fire retardant material' and the other (the Backcountry tent) states that 'it is NOT.....and will burn). Spoke to Jeff at Black Diamond about it Thursday or Friday of last week. He was perplexed as well and thought that perhaps REI may carry both versions. Apparently it is possible to purchase all Bibler models, (or at least the Eldorado), with or without the fire retardant coating.I'm pretty sure the Tempest can be purchased either way as well, as I had spoken to someone a while back about that particular model. So I guess it's 'caveat emptor', if one is concerned about breath-ability with respect to flame-retardant tents.
