Single-wall tents have had a bad press for trekking, and for good reason - they simply couldn’t handle condensation. However, with our new X-tex fabric, we believe that our s20 sigma will quickly develop widespread acceptance for lightweight backpacking.

The s20 sigma is a simple 2-pole dome with a third short transverse pole to stiffen the structure, increase the internal volume and create a steeper entrance wall/door. The s20 can be pitched quickly and it requires a minimum of pegging to secure it.

At 1.75 kg, the s20 sigma is an incredibly spacious tent for two people. Tall people will love its extra length and generous ceiling height.

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.
