Lightwave's Sigma S15 is a roomy 4 season tent at just over 1.1kg with an innovative breathable single skin design. The design stands out in a number of ways but the most important thing is that it works really well all year round in varied UK conditions.
In 2016 Lightwave launched it's first single-wall trekking tents: the Sigma range. After two years on the market and in response to feedback from users, we are updating the range for 2019. The existing S10 was considered so big for its size that it should really be called a 1-2 person tent, and that we could easily make a smaller, lighter true 1 person version.
So; The old S10 has been renamed the S15 Sigma to reflect it's true size. A new smaller version has been introduced as the S10 Sigma. Finally the S20 Sigma has been re-designed and will now have two porches/doors (one each side) and be known as the S22 Sigma.
Three other changes have been introduced for 2019 on all models; there are double eyelets at each pole-end to give more flexibility for inserting poles, the pole sleeves are now made from siliconised fabric to greatly reduce friction, and the doors have been enlarged for easier access.
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, 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.
Lightwave's S15 Sigma Tent replaces the old S10 version, in terms of keeping the same dimensions, as it provides a generous space for solo campers. This innovative tent has been a success in some of the most changeable and challenging conditions in the UK. It has successfully battled high winds, rain, huge temperature swings and most importantly for a single-skin tent, condensation. The tent is quick and easy to set up in all conditions, combines practical and durable materials making it a joy to use. Whether you're heading up onto the Cairngorm Plateau or camping in lowland valleys this tent works really well.
The range has been tweaked to offer more of a range in terms of sizes. The Sigma's still use the innovative single skin design with X-Tex coating which made them such a success in the first place. This fabric still does an amazing job of managing moisture that has often been the downfall of other single-skin tents. The new version of the Sigma has seen improvements to the pole sleeves and inserts while the doors have also been enlarged to allow easier access.
