Description
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 outer fabric, Oxford 240 PU 2000 inner fabric, and an aviation-grade B95T1 aluminum frame. The included removable Oxford floor, protective skirt, sealed exterior seams, mosquito-net doors and windows, transparent window panels, organizers, guy lines, standard pegs, ice pegs, repair kit, carry bag, and instructions complete the setup for long hours outdoors.
With room for up to 6 people without a stove or up to 5 people with a stove, Cuboid 4.40 is a true basecamp shelter for buyers who want fast setup, stove-ready performance, two-room flexibility, and reliable four-season protection in one tent.

Before Use
Precautions and recommendations
When assembling and reassembling the tent, be careful with the frame to avoid injuries.
Check tent layers before setup. The outer and inner layers may stick together during storage. Before setup, unfold the tent and separate the fabric so the layers slide freely. This ensures smooth assembly.
Choose a stable, level campsite. Do not set up the tent near dead trees, loose branches, power lines, steep slopes, or areas where water may collect.
Securely fasten the tent using all required pegs and guy lines.
In windy weather, do not set up the tent near trees. Do not set up or use the tent in sustained winds or gusts over 38 mph.
Provide continuous ventilation inside the tent, especially when using a wood stove.
Use a compatible wood stove only with the integrated stove jack and according to the stove manufacturer’s safety instructions. Stove sold separately.
Keep the stove, stove pipe, hot surfaces, and sparks away from tent fabric, gear, and bedding. Do not leave a burning stove unattended.
Ensure an unimpeded exit from the tent at all times.
It is forbidden to use gas, gas equipment, grills, or liquid fuel devices inside the tent.
The use of open flame sources outside of an approved compatible stove setup is prohibited inside the tent.
Remove snow buildup from the roof during winter use.
Dry the tent completely before storage.
Do not allow children to use the tent without adult supervision.
