HEIMPLANET THE CAVE vs RBM Outdoors Panda Air Medium
Both cost $999.00 as of November 3, 2026 — the Cave at weekends and the Panda Air Medium at Amazon — so this is a choice about use, not price. Buy the Cave for two or three people on weekend and three-season trips who want a fast, stable airbeam dome that packs at 4.8 kg. Buy the Panda Air Medium for cold-weather base camping with a wood stove, where its stove jack, canvas walls and standing height matter more than its 35 kg packed weight.
