The X3 Bunker is the latest addition to the crux range and our biggest tent. Like the smaller X2’s, the main inner tent has an asymmetric geodesic design, but unusually, configured around five poles. The benefit of the fifth pole is to help create more vertical walls for greater space, a stronger roofline for improved snow-loading, and smaller wall panels for better inner-fly separation.

Like all crux tents, the X3 Bunker is made from the strongest fabrics available to ensure not only full weather protection, but long-term durability as well.

The X3 Bunker has two porches. The main front porch has two doors, one on each side. The rear porch has a single door. The X3 has a perfect balance of space, strength and low weight.

The X3 Bunker is only available in red at the moment.

Care & Maintenance

Always ensure the tent is completely dry after a trip before packing it away for any length of time.

Flysheet cleaning
The best way to do this is simply to pitch the tent and wipe down with a cloth using a warm water and detergent mix. Flysheets can get stains and mildew (from being stored in a damp condition) – once these occur, they are almost impossible to remove. Never machine wash.

Groundsheet cleaning
As with the flysheet, wipe down with a cloth using a warm water and detergent mix. Never machine wash – this will cause the PU coating to delaminate.

After time, the elastic in the poles may lose its stretch, and the poles not fold away. It is possible to remove a pole foot at one end (these screw out), untie the elastic and pull it through until there is sufficient tension. Retie it to the pole foot, cut off the elastic and screw the pole foot back in. Do not let go of the elastic or you will find yourself re-threading all the sections!

Flysheet seams
Although the integrity of the seams is in most cases very good, occasionally there is insufficient tension in the stitching, which means some water can seep in. This can be rectified by applying seam-sealant. The area most susceptible to this is around the vent panels (as sewing three panels together is more difficult that a straight seam joining just two panels). (This does not apply to the X1 single-skin tents).
