The X3 Bunker is the latest addition to the crux range and our biggest tent. Like the smaller X2s, the main inner tent has an asymmetric geodesic design, but - unusually - is 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 offers a perfect balance of space, strength and low weight.

Extended, spacious front porch with a door on each side

Care & Maintenance

Always ensure your tent is completely dry after a trip before packing it away for any length of time. Both flysheets and inners can get stains and mildew if stored in a damp condition – and once these occur, they are almost impossible to remove.

Flysheet cleaning
The best way to clean your X3 Bunker is simply to pitch the tent and wipe down with a cloth using a warm water and detergent mix. 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.

Over time, the elastic cord inside the poles may lose its stretch. In this case, unscrew the pole foot at one end, untie the elastic and pull it through until there is sufficient tension. Retie it to the pole foot, cut off the excess elastic and screw the pole foot back in. Don't let go of the elastic or you will find yourself re-threading all the sections!

Flysheet seams
Very occasionally, insufficient tension in the stitching may mean that some water can seep through tent seams. The area around the vent panels is the most susceptible to this, for the reason that sewing three panels together is more difficult that sewing a straight seam joining just two panels.
Any such water seepage can be easily rectified by applying seam-sealant.
Before you ask: we can’t tape the seams of our X2 tents because they are silicon-coated on both sides, and tape just doesn’t stick properly.
