The s15 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 s15 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 s15 can be pitched quickly and it requires a minimum of pegging to secure it. We originally considered the s15 sigma as a one-person tent, but it is so roomy in fact that we suspect many will be used by two people keen to save weight - hence the one/two person classification. At 230 cm long, with near vertical walls and exceptional height, we think the s15 sigma accommodates tall people better than any other tent. And it weighs less than 1.5 kg, fully packed and with everything included.
This is the new 2020 version. The older 2018 model (and the original s10 and labelled as such) is available at this link https://www.lightwave.uk.com/product/shop/tent/s15-s10-sigma
