Anybody wanting both a light mattress and one that is relatively warm (R value of 3 or more) will pay through the teeth for good quality in this category. Both the Big Agnes AXL insulted and the Thermarest Neo Air XTherm are $180. and $200. respectively. Even REI's Flash insulated mattress is $119. YIKES! I really lust after the Big Agnes AXL insulated at 10.5 oz. for a regular in mummy shape but my lust is dampened by the $180. price. And I detest the crinkly noise of the Neo-Air. Had one and took it back to REI. I had the "privilege" of orally inflating my Neo-Air at 9,500 ft. and getting light headed in the process. Thankfully some air mattress companies make stuff sacks that double as bag inflators. So I may have to lug my 1 3/4 lb. Thermarest Trail Pro self inflating mattress next hunting season or give in and get the BA AXL on an REI 20% off sale. Eric B.
