UOG TOP PICK - Lightwave Sigma S10 Tent - We've singled out Lightwave's Sigma S10 as one of our top recommendations because it is a roomy 4 season tent for under 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. 

Lightwave says:

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.

We're working out what we think about Lightwave's S10 Sigma Tent, we'll add our comments here in due course.

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.

Help and advice:
 
 
 
  • 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.
  • The porch of the sigma tents uses the same lightweight silicon-coated fabric used on our hyper and ultra ranges. Silicon-coated fabrics are the most durable and long-lasting available, particularly when minimum weight is also an important criterion.
  • 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. With most of our tents, we don’t generally advocate the use of a footprint, but we recommend this where it is appropriate to do so – 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.
  • We use the 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 (ie non 7001-T6 alloy which is employed in probably 90% of all backpacking tents in the world.)
  • Pegs are very important – without them, no tent could withstand anything more than the slightest breeze. Sigma tents use our 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 our Flash pegs (which are literally “half a Lightning" peg).
  • Sigma guylines are made of standard 2.0 mm nylon. They work, and with our Linelok adjusters they work and adjust very well.

First Impressions - why buy and first night try

Lightwave Sigma S10 Tent first impressions (Note: this is the NEW S10, not the one now called the S15) My most-used and favourite 1 man tents over the years have been an Aztec Esquina Solo free standing 3kg, for kayaking and a Nordisk Telemark 1 LW <1kg for backpacking, and more recently a ZPacks Plexamid 500g, for long thru-hikes. I still love and use all of these tents. However, I bought the Lightwave Sigma S10 because I want a relatively free-standing, single skin tent with minimal footprint that can be used all-year round for stealthy wild camping. According to the manufacturer, this tent should fit all that criteria. The problem with the Telemark’s outer layer of sil-nylon is that it soaks up rain and condensation that cannot be wiped away so you have to pack a wet, heavy tent, even after wiping. (The Esquina is the same, but I don’t carry it on my back). The Plexamid’s DCF (cuben fibre) doesn’t soak up water, so rain and condensation can be wiped off and it can be packed dry. It’s larger size means that a wet inside layer is not a problem. The Plexamid is a trekking pole tent, so it needs a trekking pole and guylines hence its footprint is larger and pitching options are more restricted. The Sigma’s nylon body is carbon coated inside and claimed to absorb and transmit moisture through the material to the outside. Hence, brushing against the inside of the single layer smaller size tent is less of a problem. I have yet to see if it soaks up much water into the weave. It is free standing, so not dependent on guy-lines unless the weather is windy. It does need front and back pegs to hold the awning out and brace the back wall. I have just bought this tent and have only tried it for one cold, damp night in the garden, but wanted to test it for size and condensation performance. The build and all the materials look very high quality. Size is fairly minimalist, but quite usable in my view and there was a good amount of headroom when sitting up (I’m 5ft 9in) and good clearance for head and feet when laying down in a sleeping bag on a 50mm mat. The inside of the tent body remained dry to the touch all night, as promised, but slightly damp nearer the top. The awning is made from normal ripstop nylon and was soaked with dew and condensation, so I wiped it off, but it was still wet through the weave. Some of the droplets dripped on me and the inside the tent when exiting. I think it should have the same material as the main body. The bathtub groundsheet is also ripstop nylon and by morning this felt damp on the vertical walls near my breathing. The guy-lines are nylon and I think a tent of this price and standard should come with 1.6mm Dyneema, which is lighter and doesn’t absorb moisture like nylon. The pegs are as good or better than other high-end tents, adding 105g, though I may change mine to Swiss Pirhana 90mm at 3g each, = 30g. I am looking forward to trying my new tent in some real wild camping situations and will do a full report after that.

Excellent one man tent

Superb tent. Amazingly stable and easy to pitch. The material works really well to avoid condensation - yes there was a little but never dripping on me and would take this for the increased headroom. I did have a slight issue with one pole but UOG sorted this immediately. Hope I get many years of use out of this.
