Hilleberg Nallo 2 GT

How much it adds to your pack. This is the whole tent: two people sharing can split it. 3: Below average. Fine for some trips, not others.

Hilleberg's minimum weight is 2.4 kg (fly, inner and poles only), in the 2.0-2.69 kg band; the extra pole and bigger fly add about 0.4 kg to the Nallo 2. Complete with pegs and bags it is 2.9 kg. Two people sharing carry about 1.2 to 1.5 kg each.

How well it keeps out heavy, long rain. 8: Clearly better than most.

Hilleberg's handbook gives Kerlon 1200 (the Nallo's fly) as 5,000 mm HH (ISO 811), in the 3,000 mm+ band, and the Red Label floor as 15,000 mm, so no point is taken off. Some shop pages and reviews quote 10,000 mm for the fly; Hilleberg's own 2026/2027 handbook says 5,000 mm, so we use that. The printed figure alone gives 8 at most: a 9 or 10 needs 3 reviews that say it stays dry in real storms.

How steady it stays in strong wind on open ground. 8: Clearly better than most.

Not enough evidence: only Walkhighlands tested the GT itself (several nights of pouring rain in Scotland and a trek in Iceland) and found it stable in high winds as long as it isn't pitched side-on. The many Nallo 2 reviews are of the smaller-porch version, so they don't count for the GT.

Room to lie, sit up and keep kit inside. 6: A bit better than average.

Hilleberg gives 2.6 m² of inner floor for two people: 2.6 / 2 = 1.3 m² each, in the 1.15-1.34 band. The inner is the same as the Nallo 2: about 220 cm long and 100 cm high at the front. The GT's porch is 2.3 m², much bigger than the Nallo 2's 1.3 m².

How much room it takes in your rucksack. 4: A bit below average.

Hilleberg's packed size is 48 x 18 cm: 3.1416 x 9 x 9 x 48 = 12,215 cm³, so 12.2 L, in the 10-14.9 L band. This is with the poles and pegs rolled inside; packing the tent and poles separately makes it smaller.
