Launched in 2013, the 'MTN' styles are optimised for mountain trekking. Their unique design yield exceptionally strong tents that are nevertheless incredibly light at 2.75 kg and 3.15 kg for the 2 and 3 person models respectively. The mtn design combines a compact footprint and a porch with a high ceiling for safe cooking. Panels of Cuben fabric in the porch area reduce weight, increase strength and allow some light to enter.
The mtn tents are built around our standard three-pole semi-geodesic inner tent designs of the g20 and g30, 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 and rolling it back.
All the fabrics, poles and components used in the mtn range are of the highest specification with emphasis on strength and durability rather than light weight. In fact, the g20 mtn shares exactly the same specification as our polar exploration model, the t25 arctic. Being a g20 means it is fully compatible with inners/flysheets of any other g20 model in the ultra and trek ranges.
65 g/m2, 50d nylon 6.6 ripstop, silicone-coated on both sides, 7000 mm hydrostatic head,
18 g/m2, Dyneema/nylon non-woven fabric (Cuben), 10,000 mm hydrostatic head.
The mtn 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!
120 g/m2, 70d nylon taffeta, TPU laminated
10000 mm hydrostatic head, factory-taped seams
The mtn 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) and better abrasion resistance than conventional liquid-applied PU coatings.
35g/m2, 30d nylon 6.6 ripstop, DWR treated
DAC 9.60 mm Featherlight NSL poles
The g20 mtn uses 10.0 mm DAC Featherlight NSL poles. Quite simply, these are the most reliable poles we know.
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 g20 mtn to ensure it can be secured in all ground conditions.
2 mm Dyneema/polyester, 3 m length, mini-Linelok adjusters
The g20 mtn comes with our Dyneema guylines, a 2 mm blend of Dyneema and 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
