RBM Outdoors Cuboid 4.40 is a spacious double-layer 4-season hot tent built for winter camping, ice fishing, hunting, remote basecamps, bushcraft trips, and family camping in changing weather. Its tent-within-a-tent design uses a weather-resistant outer shell and a separate inner tent with an insulating air gap to help reduce direct cold transfer, manage condensation, and create a more comfortable living space across the seasons. The fast umbrella-style frame sets up in about 5 minutes, giving you a large shelter without a complicated pole assembly. Inside, Cuboid 4.40 offers 101.82 sq ft of usable space, 74.80 in peak height, two entrances, four windows, and a removable partition that lets you use the tent as one open room or divide it into two separate zones for sleeping, cooking, gear storage, changing, or relaxing. Built for cold-weather trips, Cuboid 4.40 features one integrated 90 mm / 3.54 in stove jack for compatible wood stove use, helping you heat the shelter, dry clothing and gear, and extend your camping season into late fall, winter, and early spring. The stove is sold separately. Durable materials make this shelter ready for demanding outdoor use: Oxford 300 PU 4000 o
