RBM Outdoors Hexagon Hot Tent Review

The RBM Outdoors Hexagon is a large double-layer frame tent built around a quick umbrella-style setup. It offers 12.6 m² (135.62 ft²) of usable area, standing room, three doors, five windows, a removable floor, and a 90 mm (3.54") stove jack. The shape is especially useful when a group wants a shared central space without assembling a loose pole system piece by piece.

Its published capacity is up to nine people without a stove or up to six with a stove. A more realistic furniture-based reference is up to six standard cots without a stove or up to four with one. Those figures make the tradeoff clear: heat equipment and safe clearances use part of the floor area.

Fast umbrella-frame setup and group-sized space

The integrated frame opens in about 5 minutes. Its aviation-grade B95T1 aluminum construction uses 10 mm rods with 12 mm roof rods. Because the main frame stays with the tent, setup centers on opening the structure, positioning it, and anchoring it rather than identifying and joining a separate set of poles.

The exterior measures 4.50 m (177.16") corner to corner and 3.90 m (153.54") wall to wall. Exterior height is 2.20 m (86.61"); the interior ceiling height is 2.10 m (82.67"). Published capacity is a maximum occupancy guide, not a promise that every person can also use a cot and keep full stove clearances.

Double-wall construction and condensation management

The outer shell is Oxford 300D PU4000, while the inner tent is Oxford 240D PU2000. The air space between them helps reduce direct heat transfer and gives moisture a route away from the occupied inner wall. That design helps manage condensation, but it cannot eliminate it: ventilation, wet clothing, cooking, occupancy, and outside temperature still matter.

The tent is designed for four-season use within a published operating range of -50 °C to +45 °C (-58 °F to 113 °F). This is an equipment operating range, not a guaranteed indoor comfort range. Sleeping systems, wind, humidity, snow load, anchoring, and heating practices determine real campsite comfort and safety.

Removable floor and optional insulated floor

A removable Oxford floor is included with the tent. For camps where more separation from the ground is useful, the optional three-layer floor combines Oxford 300D PU4000 outer layers with a Foil Isolon insulation layer. It measures 5.16 m (203.15") across, covers 17.56 m² (189.01 ft²), and weighs 6 kg (13.23 lb) net.

The upgrade adds ground insulation and a more finished walking and sleeping surface. It does not replace site preparation, an appropriately rated sleeping pad, or regular checks for water, ice, and sharp objects beneath the tent.

The inner tent, windows, organizers, gear loft, and stove area

Doors, windows, awning, and storage

Three doors reduce traffic through a single entrance, and five windows can accept the five included removable TPU inserts. One wall can flip upward to form an awning using the four included awning poles. Inside, two detachable organizers and one gear loft keep small items off the floor.

The anchor kit includes 20 regular pegs and 14 ice screws, plus six 6 m (19.69 ft) guy lines and one 20 m (65.62 ft) line. The published maximum recommended wind speed is 61 km/h (38 mph). Treat that as an upper limit, not a target: poor soil, damaged anchors, gusts, exposure, or accumulated snow can require taking the tent down sooner.

Stove jack and optional Caminus M stove

The integrated stove jack accepts a chimney up to 90 mm (3.54") in diameter. A stove is not included with the standard tent. When the Hexagon is paired with the optional Caminus M, the stove uses an 80 mm (3.15") chimney and five 485 mm (19.09") pipe segments, reaching a published total height of 2.80 m (110.23").

Caminus M is made from AISI 430 stainless steel and has 4 mm (0.16") fire-resistant ceramic glass side panels rated up to 750 °C (1382 °F). The assembled stove measures 330 x 690 x 600 mm (12.99 x 27.16 x 23.62"), and its internal firebox measures 250 x 500 x 250 mm (9.84 x 19.68 x 9.84"). It weighs 16.5 kg (36.37 lb) net.

Verified technical specifications

Where the Hexagon fits best

For group camps, the circular floor plan creates a shared center without a narrow corridor. Hunters and longer-stay campers can place cots around the perimeter and keep the central area for movement, gear, or a properly installed stove. Ice screws and the removable floor support winter campsite use, but the surface and weather still need active monitoring.

The main limitation is transport. At 43.2 kg (95.24 lb) net and 228 cm (89.76") long when packed, the Hexagon is a vehicle-based shelter. Check cargo length before travel and plan for more than one person to handle the bag when practical.

Final assessment

The Hexagon earns its place as a group hot tent through a practical combination of usable space, quick frame deployment, double-wall construction, three entrances, large windows, and a stove-ready layout. Its weight and packed length make it a basecamp shelter, not a portable trekking tent. Used within its weather limits and anchored carefully, it offers a flexible four-season interior for families, fishing groups, hunting camps, and extended stays.
