Big Agnes Divide

The Big Agnes Divide is a warm-weather inflatable sleeping pad built around vertical I-beam baffles that keep the sleeping surface stable without excess material. At an R-value of 1.5, it is rated for summer conditions only — enough insulation to take the chill off warm ground but not for shoulder-season or winter nights, where a supplemental pad or R-4+ model would be needed. At 539 g in the Regular size (50 x 183 cm) and packing down to 10.2 x 17.8 cm, the Divide sits in the lightweight-but-not-ultralight bracket for a full-length pad. Its 8.9 cm thickness is generous for a summer pad, trading a bit of pack volume for sleeping comfort compared to thinner minimalist options. Built from recycled nylon ripstop on top and bottom, it ships with a pump sack, stuff sack, and repair kit — everything needed on trail without extra purchases. It suits backpackers and thru-hikers doing warm-season trips who want comfort and packed size that don't demand shaving every last gram, but who don't need cold-weather insulation.
