For the Kickstarter, we are only offering one size Air Pad (20 x 72 x 3.25 inches).
If we're successfully funded, we would definitely like to offer multiple products including larger (and smaller) Air Pads. You can sign up for NEW Product Alerts here: http://www.oceanicinnovation.com/windcatcher/new-product-alert-signup
FUN FACT: With the Windcatcher, a pad that is twice as large does not take twice as long to inflate. Our original pad was 2.5 inches thick. When we discovered we could inflate a pad that is 3.25 inches thick in the same amount of time (and breaths), we went with the thicker pad.
