Inflatable pad or Foam?

[Danalex]

Not familiar with Academy but you definitely won't find the pricey Exped Downmat at Walmart. They are available at REI.

Many use the basic blue closed cell foam mat from Walmart. I use Under quilts but if I did use a foam pad I'd try scoring the underside of the pad like a cut mango to help it flex.

You put the cut side up or down?

If down it opens the cuts and decreases in the insulating values I assume.
