G20 MTN Mountain 2 People Tent

Product Description

Lightwave g 20 MTN Mountain -  2 People Tent With Standard Porch

The g 20 mtn is a tough, high-performance, 5-season, all-terrain, semi-geodesic tent for 2 people.

The Mountain styles have been optimised for mountain trekking. Their unique design yield exceptionally strong tents that are nevertheless incredibly light at 2.75kg & 3.15kg for the 2 & 3 person models respectively. The  Mountain design combines a compact footprint & a porch with a high ceiling for safe cooking. Panels of Cuben fabric in the porch area reduce weight, increase strength & allow some light to enter.

The  Mountain tents are built around our standard three-pole semi-geodesic inner tent designs of the g 20 & g 30, as used in the ultra and trek ranges. However, the flysheets depart from convention in featuring a fourth, long pole that is inserted along the ridgeline. As well as enhancing the overall strength of the tents (for example under snow-loading), this also creates height in the porch area. The interior volume of the porch can also be increased by unclipping the inner tent from the flysheet & rolling it back.

All the fabrics, poles & components used in the  Mountain range are of the highest

Specification with emphasis on strength & durability rather than light weight. In fact, the g 20 Mountain shares exactly the same

Specification as our polar exploration model, the t 25 arctic. Being a g 20 means it is fully compatible with inners/flysheets of any other g 20 model in the ultra & trek ranges.

Technical Specifications:

Flyshee​t                     

• 65 g/m 2, 50d nylon 6.6 ripstop, silicone-coated on both sides, 7000 mm hydrostatic head,
• 18 g/m 2, Dyneema/nylon non-woven fabric (Cuben), 10, 000 mm hydrostatic head.

The mountain flysheet is made from nylon 6.6 with a yarn thickness of 50 denier. Almost twice as strong as fabrics woven from lighter yarns, this is the best choice for any serious mountain, expedition or polar tent. The strength of the mtn 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 7000 mm. It is combined with the use of Cuben panels in the porch areas. Cuben is a fabric that was developed for the sails of the America Cup yachts. At almost a third of the weight of the 45d nylon, it has more than twice the strength. The downside is its cost – well over five times that of conventional nylon fabrics per square metre! 

Groundsheet          

• 120 g/m 2, 70d nylon taffeta, TPU laminated
• 10000 mm hydrostatic head, factory-taped seams                

The mountain groundsheet is made from a 70-denier nylon ripstop with a laminated thermo-plastic polyurethane (TPU) coating. TPU coatings have greater bonding durability (to the substrate fabric) & better abrasion resistance than conventional liquid-applied PU coatings.

Inner canopy              

• 35g/m 2, 30d nylon 6.6 ripstop, DWR treated

Poles                          

• DAC 9.60 mm Featherlight NSL poles

The g 20 mountain uses 10.0 mm DAC Featherlight NSL poles. Quite simply, these are the most reliable poles we know

Pegs   

• Lightning pegs, 11 g each, square section
  Flash pegs, 7 g each, narrow profile

Pegs are a vital component of every tent. Lightwave offers a range of different pegs with the g 20 mtn to ensure it can be secured in all ground conditions.

Guylines                     

• 2 mm Dyneema/polyester, 3 m length, mini-Linelok adjusters

The g 20 mountain comes with our Dyneema guylines, a 2 mm blend of Dyneema & polyester with a breaking strain of 180 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: 

The g 20 mountain is pitched inner-first. Lightwave is an ardent supporter of this pitching method for the following reasons:

1. 1. It gives greater structural integrity. Because the poles run through sleeves on the inner canopy, they directly tension & support the walls & built-in groundsheet of the inner tent & give it taut & stable three-dimensional shape. In the outer-pitch system, where the poles pass through sleeves on the flysheet & there is no built-in groundsheet, the walls must be “tied” together at ground level by webbing straps & the overall structural rigidity is not as good.
   2. It allows the flysheet to be tensioned better & more easily. Without external pole sleeves, inner-pitch tents have a more streamlined, “slippery” profile & thus a greater ability to withstand high winds.
   3. It makes for a lighter tent & a simpler construction, since it does not require the connecting mechanisms needed to secure the inner tent to the flysheet.
