In 2016 Lightwave launched their first single-wall (single skin) trekking tents: the sigma range.

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.

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 these new sigma tents incredibly light, but they are also extraordinarily spacious. These tents are optimised for trekking and feature a large porch for storage, 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.

Specifications:

Flysheet

75 g/m² 20d nylon ripstop
X-tex coating 20,000 mm hydrostatic head
Multiple guypoints
Continuous pole sleeves

The sigma tents are defined by the X-tex fabric used for the flysheet. This is unique to Lightwave and has an astonishing ability to manage the condensation that has plagued single-wall tent designs in the past. The X-tex fabric is heavier than most flysheets due to its coating, but the result is a hydrostatic head (i.e. waterproofness) that is far higher than the standard 3000-5000 mm found in nearly all tents. The coating always feels dry to the touch and is also quite light impermeable.

Porch wall
51 g/m2, 30d nylon 6.6 ripstop,
Silicone-coated on both sides, 5000 mm hydrostatic head

The porch of the sigma tents uses the same lightweight silicone-coated fabric used on the hyper and ultra ranges. Silicone-coated fabrics are the most durable and long-lasting available, particularly when minimum weight is also an important criterion.

Groundsheet
75 g/m² 50d nylon taffeta
PU-coated with 5000 mm hydrostatic head
Bath-tub construction with reinforced corners and taped seams

The sigma groundsheet is made from a durable 50-denier taffeta (plain weave). The 50-denier fabric is a reasonable balance between the need to save weight and provide adequate protection from abrasion and moisture. We recommend the use of a footprint where it is appropriate – in other words, when you know ground conditions are going to be harsh, or weight being carried (a footprint is an additional 200 g) is not quite so critical.

Inner wall
25g/m2, 20d nylon 6.6 ripstop, DWR treated
Mesh window

Poles
DAC 9.35 mm Featherlite (aluminium alloy)

Lightwave use DAC Featherlite poles on the sigma tents simply because these have proved themselves time and again as the most reliable of the lighter weight alloys (i.e. - non 7001-T6 alloy which is employed in probably 90% of all backpacking tents in the world.)

Pegs
Lightning pegs, 11 g each, square section
Flash pegs, 7 g each, rectangular section

Pegs are very important – without them, no tent could withstand anything more than the slightest breeze. Sigma tents use the Lightning peg – similar in weight to most standard pegs, but substantially stronger and capable of living with some serious abuse. Costing four times as much as normal wire pegs, these are seldom seen on all but the most highly specified and expensive tents. Supplementing these for non-critical peg-points are Flash pegs (which are literally “half a Lightning" peg).

Guylines
2.00 mm nylon, 3 m length, Linelok adjusters

Sigma guylines are made of standard 2.0 mm nylon. They work, and with Linelok adjusters they work and adjust very well.

Pitching

One of the benefits of single-wall tents is that they are easy and quick to pitch and take down. Effectively, the sigma tents are pitched “flysheet first” as this is the only way – there is no separate inner. The poles are inserted into the flysheet and sprung into place, and the tent is then pegged out.
