Big Agnes pad+bag system in warm weather

The BA bags come in full zip too, no? When it's warm, you can lay directly on your pad — then drape the bag on you partially as desired.

"The BA bags come in full zip too, no?"

I couldn't verify that

"When it's warm, you can lay directly on your pad — then drape the bag on you partially as desired."

I'm used to stretch my legs and arms outwards when sleeping warm: if the bag remains attached to one side of the pad, that wouldn't be possible, I presume

Coming to think of it, since the bag's bottom is just a piece of fabric, zipping or unzipping probably doesn't matter much. It's not going to "butterfly out" like a quilt.

OTOH, as above, if you don't attach the bag to the pad, then you are free to drape the bag on you. However, it may not be wide enough for you if your arms and legs are stretched out. OTOH, if it's really warm, maybe that's a good thing…
