Telemark 2.2: 2 people with an entrance on each side, 1.12 kg as LW (2.0) and 1.9 kg as PU.
Halland 2: a tunnel-shaped tent with good sitting height, 1.48 kg as LW, 2.47 kg as SI and 3.15 kg as PU.
Oppland 2: a tunnel tent with a large porch, 1.7 kg as LW, 2.9 kg as SI and 3.8 kg as PU.
Svalbard 1: 1 person, 1.75 kg as SI and 2.1 kg as PU. The front can be rolled away for the view.
Otra 2 PU: 4.35 kg, with an entrance and porch on both sides and an all-mesh inner tent.
Seiland 2 SP: a tunnel tent in silicone-coated polyester with a flysheet that reaches the ground.
Fabric: ULW to PU
ULW and LW: silicone-coated nylon with a 1,600 mm or 2,000 mm flysheet. The lightest choice.
SI: 40D nylon with a 3,000 mm flysheet and a 10,000 mm floor, for longer trips and rough ground.
PU: polyester with taped seams and a 3,000 mm flysheet. Heavier and bulkier, and waterproof apart from zips and openings.
Inner or outer pitched
Most models are outer-pitched, so the inner tent stays dry when you pitch in rain. The Halland 2 PU and Otra 2 PU are inner-pitched, with the inner tent up first. The Halland, Oppland and Seiland tunnel tents need to be pegged out, ideally with the narrow end into the wind.
Space on longer trips
For a single night the minimum will do. On longer trips, a tent you can sit up in and a porch for cooking and wet gear make the difference.
Car camping for two
For car camping, the Asgard Tech Mini and Ydun Tech Mini are compact two-person tents of about 6 kg on aluminium A-frame poles.
