The s22 sigma is the first of a new generation of single-wall tents where it can be truly said that condensation is no longer a problem. It is made from a lighter version of the X-tex fabric launched by our sister-brand crux for its range of X1 mountain bivouac tents.

The s22 sigma is a simple 2-pole dome with an additional brow pole to increase internal volume and height. It has two porches - one on each side. It can be pitched quickly and requires a minimum of pegging to secure it. It comes at a fully packed weight of 1.71 kg.

Care & Maintenance


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


The poles consist of a number of sections linked together with shockcord. Over time, the shockcord stretches and the tension holding all the poles together reduces. This increases the risk of one section sliding off the ferrule of the adjacent one, resulting in what we call a J-tear failure. If you notice this, remove the pole-foot from one end, cut the elastic shorter and re-install it.
