RBM Outdoors Cuboid 4.40 - All-Season Double-Layer Hot Tent with Stove Jack for 2-6 People

RBM Outdoors Cuboid 4.40 is a spacious double-layer, four-season hot tent designed for winter camping, ice fishing, hunting, remote basecamps, bushcraft adventures, and family camping in changing weather conditions. Its tent-within-a-tent construction combines a weather-resistant outer shell with a separate inner tent, creating an insulating air gap that helps reduce cold transfer, control condensation, and provide a more comfortable living environment throughout the year.

The quick-deploy umbrella-style frame sets up in approximately 5 minutes, delivering a large shelter without the complexity of traditional pole assembly. Inside, the Cuboid 4.40 provides 101.82 sq ft of usable space, a 74.80 in peak height, two entrances, four windows, and a removable divider that allows you to use the tent as one open living area or split it into two separate zones for sleeping, cooking, gear storage, changing, or relaxing.

Built for cold-weather adventures, the Cuboid 4.40 includes an integrated 90 mm / 3.54 in stove jack for compatible wood stove installation, helping you warm the shelter, dry clothing and equipment, and extend your camping season through late fall, winter, and early spring. Stove sold separately.

Durable materials ensure dependable performance in demanding outdoor environments, including Oxford 300 PU 4000 outer fabric, Oxford 240 PU 2000 inner fabric, and an aviation-grade B95T1 aluminum frame. The package also includes a removable Oxford floor, protective skirt, sealed exterior seams, mosquito-net doors and windows, transparent window panels, storage organizers, guy lines, standard pegs, ice pegs, repair kit, carry bag, and setup instructions for extended outdoor use.

With space for up to 6 people without a stove or up to 5 people with a stove installed, the Cuboid 4.40 is a true basecamp shelter for campers seeking quick setup, stove-ready functionality, flexible two-room living, and dependable four-season protection in a single tent.

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.
