Lightwave t20 Hyper XT -  2 Person Tent

The Lightwave’s range of hyper tents has been developed specifically for use where low packed weight and robust all-weather performance are paramount. The hyper tents are light enough to carry on extended wilderness treks, and strong enough to withstand the worst conditions where alternative shelter is not an option.

The hyper range offers three major performance innovations:

  1. Hyper tents are completely multi-pitch. In other words, they can be erected flysheet-first, inner-tent first, or integrally.
  2. Even though the flysheet fabric is silicone-coated on both sides, the flysheet seams are factory-taped making them fully weather-proof.
  3. Hyper poles are fully maintainable in the field. Should any sections fail, they are easily removed and replaced with the spares provided with each pole set.

The fabrics used in the hyper tents strike a calculated balance between strength and weight (any thinner yarn or lower fabric weight, and fabric strength would be seriously compromised). For guylines, hyper tents use a Dyneema/polyester cord that is 80% lighter than standard nylon. Each tent comes with a range of different pegs to cover all ground conditions, from hard-packed earth to loose sandy soil.

Technical Specifications:


  • 51 g/m2, 30d nylon 6.6 ripstop, silicone-coated on both sides, 5000 mm hydrostatic head

The hyper flysheet is made from nylon 6.6 with a yarn thickness of 30 denier. There has been a trend in recent times towards the use of 20 denier or even 15 denier yarns in many lightweight and ultra-lightweight tents. Lightwave believes such fabrics lack the intrinsic strength that a flysheet needs if it is to withstand high winds and provide long-term durability. 30-denier yarn offers this strength while still remaining extremely light. The strength of the hyper flysheet is further assured by using only high-tenacity nylon 6.6, which has a higher tensile strength than normal nylon. Finally, the fabric is silicone-coated on both sides for water resistance to a hydrostatic head of 5000 mm.  As well as being the most durable and water-repellent coating of them all, silicone has another major advantage over conventional polyurethane (PU): it doesn’t affect the fabric strength. PU coatings reduce the tear strength by up to 70%, in our view making them less suitable as a flysheet coating –  especially on very lightweight fabrics which have a relatively low tear strength to start with. 


  • 70 g/m2, 40d nylon ripstop, TPU laminated
  • 7000 mm hydrostatic head, factory-taped seams

The hyper groundsheet is made from a 40-denier nylon ripstop with a laminated thermo-plastic polyurethane (TPU) coating. TPU coatings have greater bonding durability (to the substrate fabric) and better abrasion resistance than conventional liquid-applied PU coatings. This is a much tougher fabric than it looks.

Inner canopy

  • 30g/m2, 20d nylon 6.6 ripstop, DWR treated


  • DAC 9.35 mm Featherlite poles

Hyper tents use 9.35 mm DAC Featherlight poles. These are light, strong and reliable. (The earlier version of the hyper tents with the taped flysheets used Yunan 9.60 mm 7001-T6 Ultralight poles with Unit connctors).


  • Lightning pegs, 11 g each, square section (t20/30 - 4 pegs; t20/30 xt - 6 pegs)
  • Wavelight pegs, 12 g each, corkscrew design (all models - 4 pegs)
  • Titanium V-pegs, 10 g each, V-shape (all models - 4 pegs)
  • Flash pegs, 7 g each, narrow section (all models - 4 pegs)

Pegs are a vital component of every tent. Tunnel tents are of course completely dependent upon solid anchors at front and rear, but a self-supporting geodesic, too, needs to be prevented from blowing away in the breeze. Lightwave offers a range of different pegs with the hyper tents to ensure they can be secured in all ground conditions.


  • 1.50 mm dyneema/polyester, 3 m length, mini-Linelok adjusters

Hyper tents come with our Lightning guylines, a 1.50 mm blend of Dyneema and polyester with a breaking strain of 110 kg. Phenomenally light, they also absorb no water so won’t freeze up in winter. The Linelok adjusters mean they are easy to tension, even with gloves on.

Pitching Overview:

Hyper tents are multi-pitch. This means they can be pitched flysheet first, inner-tent first, or integrally with the flysheet and inner tent attached together.

  • Pitching the hyper tent integrally, with the flysheet and inner tent attached together, is the quickest and easiest method and can be completed within three minutes. This method is particularly advantageous in very wet weather.
  • When it comes to dismantling the tent, however, if the flysheet is wet (either from the weather or condensation) we recommend that you detach and fold up the inner separately and then dry off the flysheet (or at the very least, shake off any excess water) before packing it away.
  • In the case of exceptionally strong winds, pitching the tent inner-first (with the tail into the wind) will give you the strongest structure.
