BA lists no R-rating for its AXL insulated mattress.
I wonder if ti is close to Thermarest’s Neo-Air X-Therm 5.7 rating. I’s like a single light mattress i could use for all seasons.
The BA AXL insulated mattress comes closest to what I like since many years ago I owned an original Neo-Air and returned it to REI due to the noise problem. Plus the BA AXL insulated is about 7 oz. lighter than the Neo-Air X-Therm.
I kinda like the REI Flash insulated mattress but I’ve read too many reports of it failing at the weld junctions.
