The g30 trek is a very spacious three-person three-pole semi-geodesic tent that's ideal for backpacking trekking and camping all year round. There is plenty of room to spread out in making it ideal for extended stays at base camp or camping in winter where extra-bulky sleeping bags and clothing seem to take up all the space.

Lightwave says:

At Lightwave, we appreciate that not everyone is insistent upon having the very lightest tent on the market, or one using the strongest or most waterproof fabrics. For the large majority of users, in fact, what matters is that their tent will shelter them from some serious weather when it hits, is light enough to carry as part of a pack-load, and is durable enough to provide a decent amount of use for several years. And all without breaking the bank.

The trek range strikes an optimum balance between all these end-user requirements – better, we believe, than any other tent on the market – and for this reason has been the backbone of the Lightwave tent range for many years.

Lightwave trek tents are all pitched inner-first, the system we like best (see why under pitching) and which is the basis for their outstanding performance in wind and bad weather.

Trek fabrics and components are selected for maximum performance and durability at the most reasonable price, while weight is kept to a sensible minimum thanks to Lightwave’s no-frills approach to design.

The Trek range of tents are designed for trekking, back packing and year round camping. They are all pitched inner-first which is the basis for their outstanding performance in wind and bad weather. This semi-geodesics Trek series is identical in design to the Hyper and Ultra series, but uses alternative fabric specifications to achieve more accessible price levels. This gives you a high performance tent for a lower price tag with just a slight increase in weight. 

The Trek series tents are all 4 season tents which are tough and fully waterproof. The designs vary from 2 to 3 person tents with the choice of an extended porch for extra space.

Help and advice:
  • The trek flysheet is made from 40-denier nylon, which strikes an excellent balance between weight and strength. Like all Lightwave tent flysheets, it uses high-tenacity nylon 6.6 yarn (which has a higher tensile strength than normal nylon) and is silicone-coated on both sides (for water-resistance). Silicone coatings maintain the inherent strength of the fabric, whereas the conventional polyurethane (PU) coatings typically used on most tents reduce the tear strength by up to 70%.
  • The trek groundsheet is made from a very robust 150-denier polyester (except on the compact t10 models which use a 70-denier nylon). This is an area where many tents use 110-denier or even 70-denier fabrics to save weight and keep manufacturing costs down. For the user, however, this can be a false economy, since lighter groundsheets often need the additional reinforcement of a footprint (a separate layer of fabric between groundsheet and ground), which adds up to an even heavier tent as well as extra cost.
  • Trek poles are made of the same 7001-T6 alloy employed in probably 90% of all backpacking tents in the world. Whilst there are lighter alloys around, we always come back to the 7001 series because it is so reliable and resilient. Given that 90% of customer service on tents involves pole replacements, the 7001 poles give both us and our customers the least amount of hassle.
  • Pegs are very important – without them, no tent could withstand anything more than the slightest breeze. Trek 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.
  • Trek guylines are made of standard 3.0 mm nylon. They work, and with our Linelok adjusters they work and adjust very well.

All the trek tents, geodesics and tunnels alike, are pitched inner-first. Lightwave is an ardent supporter of this pitching method for the following reasons:

1. It gives greater structural integrity. Because the poles run through sleeves on the inner canopy, they directly tension and support the walls and built-in groundsheet of the inner tent and give it taut and stable three-dimensional shape.

2. It allows the flysheet to be tensioned better and more easily. Without external pole sleeves, inner-pitch tents have a more streamlined, “slippery” profile and thus a greater ability to withstand high winds.

3. It makes for a lighter tent and a simpler construction, since it does not require the connecting mechanisms needed to secure the inner tent to the flysheet.
