The Gear Doctors Apollo Air is an insulated inflatable pad with an R-value of 5.2 measured to the ASTM F3340-18 standard, placing it in the independently verified category rather than relying on a manufacturer's own, non-comparable methodology. A rating like that is suited to year-round use, including winter conditions on snow and below freezing.
An 8.1 cm thickness combined with horizontal baffle construction gives support closer to a mattress, which side sleepers in particular will appreciate. The 40D nylon top and bottom fabric with Hexagon Shield/E-LAST coating targets puncture resistance without piling on extra weight. In the Regular size the pad weighs 496 g including the included pump sack — solid, if not class-leading, for this level of insulation.
A repair kit ships in the box, a useful safeguard for any inflatable pad. The one drawback worth noting is surface noise when moving around inside a sleeping bag — a common trade-off of reflective insulation layers, worth being ready for if you're sharing a tent with others.
