So-called self-inflating sleeping pads are those that have an air valve that, when opened, can inflate in part by letting the air flow into it through the open valve.
Additional Inflation Required
These sleeping pads often require additional inflation by the backpacker blowing into the valve to get the desired firmness in the mattress.
Self-inflating pads have the advantage over closed-cell foam pads in that they can be rolled up (once all the air is pressed out) to a very small packable size.
Self-inflating pads have the disadvantage of needing a repair if punctured. Even a minuscule hole can create a leak in a pad like this, which will need to be patched. Luckily, there are patch kits available to make repairs.
Interior Pad Design
Many self-inflating pads have a diagonal or honeycomb design foam interior, which provides extra insulation and warmth.
