Really like this sleeping bag! The bottom sleeve is very convenient to hold the air mattress, no more sleeping bag sliding off it at night. Also a sleeve for the inflatable pillow or clothes for the head. I leave the air mattress and air pillow in the sleeping bag after deflation and just fold the whole thing into the front pannier of my bicycle. How easy is that! Also comes with a large printed bag for storage when not using to prevent material from compressing. Warm, as rated. Would recommend!!
