The sigma range of tents are single-wall designs made from our unique X-tex fabric that utilizes 37.5 activated carbon technology in the waterproof coating. This absorbs condensation, prevents water droplets from forming, and continues to breathe.
Single-wall tents have always been a rarity in trekking. The age-old problem of condensation has traditionally inhibited their mainstream use. The sigma range uses a new fabric technology that effectively resolves this fundamental issue. The benefits of single-wall tents are three-fold. First, using the same pole-lengths as a double-wall tent, they are much more spacious: the gap between inner and flysheet becomes part of your internal space. Second, by disposing of the inner-wall, you are eliminating a lot of fabric and therefore, saving weight. Finally, they are simpler to pitch: there is no two-step process or need for any kind of connection between inner and flysheet. As a consequence, not only are our new sigma tents incredibly light, but they are also extraordinarily spacious. These tents are optimised for trekking and feature a large porch for storage and easy access. Inside they have generous headroom making for comfortable living. Pitching is simple and quick, and the tents are virtually free-standing and require minimal pegging.
