major lower back pain

[slowhike]

Hey Tim,
Do you like the Exped Dam 7 better than your BA insulated air mattress or do you use one in the winter and one in warmer weather?

i use the BA in warmer weather & the exped in colder weather.
i have began to feel cool on bottom sleeping on the BA in the low 50s & upper 40s w/ no under quilt.
but some people seem to do fine w/ the insulated BA at lower temps.
