Lightwave

s15 Sigma

The Lightwave 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 Lightwave's 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.
