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.
