The Hillebeg Nallo 2 is world-class tunnel tent that falls awkwardly between the company's lighter three-season Anjan 2 and the heavier Antarctic exploring Nammatj 2. Our tests show that the Nallo performs well in high winds but not as well for snowloading. For real mountain winter conditions our testers reach to stronger tents like the Nammatj and for three-season use we reach to tents found in the Backpacking Tent Review or Ultralight Tent Review. We feel the Nammatj is a much better value than the Nallo, but perhaps your ideal applications aligns well with the Nallo's capabilities.

Read on for more info about the Nallo and/or check out our complete Four Season Tent Review to compare all of the winter models tested. Also consider a floorless tent—our testers' favorite type of shelter for 99% of fast and light trips—found in our Ultralight Tent Review.

Performance Comparison

Ease of Setup

The Nallo is very quick to set up. Simply peg out the ground level guy points, insert the two poles into the pole sleeves, and peg and tighten the guy lines. You can use as few as four pegs to pitch it.

Weather Resistance

The Nallo uses 9 mm DAC Featherlite NSL poles, the best available, and also the same model used on the Hilleberg Anjan 2 and dozens of other tents from Hilleberg and other brands. In contrast, the Hilleberg Nammatj 2 uses much stronger 10.2 mm poles. We've found that the Nallo is capable of handling very strong winds. We know of only a few other double wall tents that weigh a similar amount as the Nallo and handle winds better. Unfortunately, the same cannot be said for static strength; the Nallo performs only moderately well at resisting heavy snow loads and nearly broke during one night of testing. See the photo below. In such a storm it's important to attentively knock snow off the roof and vestibule, and clear it away from the sides of the tent. If it's dumping we suggest setting an hourly alarm and going outside to remove snow from the vestibule and walls, and check on the tieouts.

This picture shows 4" of heavy, wet snow on the Nallo 2. The product needs "maintenance" during heavy snowfall. You need to be inside or near it to knock snow off. The Nammatj is much stronger!!
The Nallo has many attributes that contribute to its strength and durability. Perhaps the most important is its outer tent fabric, Kerlon 1200, which is likely the third strongest woven fabric found any tent we've tested. It has a tear strength of 26.5 lbs., yet weighs only 1.47 oz/sq.yd. This is impressive performance is due to the fact that each side of the fabric is impregnated with three layers of 100% silicon, a coating far superior (and more expensive) than traditional polyurethane (PU) formulations used on most other tents. A stronger fabric is less likely to be punctured by a broken pole and less likely to tear if punctured. The silicone coating is also more resistant to UV exposure and to hydrolysis (chemical breakup of the fabric) and than PU fabrics and therefore will remain its water resistance for longer.

The Nallo has several smaller features that also contribute to its weather resistance. (1) the outer tent extends all the way to the ground. This blocks wind, snow, and virtually reduces splashback from driving rain. (2) The poles sleeves can accommodate an extras set of poles, which makes the tent significantly stronger. We haven't used this technique with the Nallo or any other Hilleberg tent, but if we were to use the Nallo in serious winter conditions we would probably want to bring extra poles. (3) Three ground straps run perpendicular to the length of the tent and absorb stress during high winds and keep the pole arcs at the proper height and tension. They can also be used as guy lines, if needed. (Hilleberg tents are then only ones we've tested that comes equipped with ground straps.) (4) The vestibule has a "door band," which keeps it in the proper shape and minimizes tension on the zippers. (5) all guy points are heavily reinforced; the vestibule adjusters are made of metal, not plastic. (6) The guy lines are made of a Spectra-polyster blend that doesn't absorb much water and doesn't stretch asmuch as cheaper nylon lines. The fact that they don't absorb water is key. With 8 guy points and 4+ ft. of cord at each point, wet lines can make a tent significantly heavier. With no sheath to separate from the core, Spectra is also more durable. The Nallo's guy lines come pre-rigged with camming adjusters. No, you don't have to spend an hour cutting and attaching lines!! The camming adjusters are super easy and very fast, too. We much prefer them to the trucker's hitch knot in cold temperatures.

The Nallo is the same size as the Anjan and slightly smaller than the Nammatj. The author has spent more than 40 nights in the Nallo and can attest to the fast that it is very comfortable for its weight and weather protection. But the extra 11 oz. to step up to the Nammatj 2 bring more interior volume, more space to sit up, and a vestibule that is better for cooking in.

Ventilation is a key component of tent design and the Nallo does well at managing condensation. Not as well as the Nammatj, which has two vents, but better than the Anajan, which lets in air by the sides and doesn't have any dedicated vents.

Unlike most similar tents from other companies, the Nallo's vestibule has a continuous zipper that hits the ground in two places, making a large arc. There are four zipper pulls that provide multiple configurations for opening the door: open from the left or the right, or pull both zippers down if you can't easily reach one of the two down by the floor. We appreciate these options.

Plenty of space for two inside the Hilleberg Nallo 2. Also note the rear vent, clothesline, and how the door unzips and stuffs into the pocket.

The Nallo's fabrics are tougher than perhaps all other double wall tents that weigh a similar amount. But the tent is significantly less durable than the Hilleberg Nammatj 2, which uses tougher fabrics all around. If you consider durability to include pole design then many freestanding single wall tents are more durable than the Nallo because they are less likely to collapse from snowloading.

Weight/Packed Size

Without stakes the tent weighs 4 lb. 12 oz. and packs down reasonably small.


Removing the inner tent leaves a strong floorless tent for summer backpacking. This can be great, particularly because the tent walls and vestibule extend to the ground and create a reasonably good seal to prevent insect from flying inside.

Hilleberg inner tents hang roughly 4" below the outer tent and can be removed quickly with elasticized toggles. The Nallo 2 is pictured here.

Remove the Nallo 2's inner tent (takes about a minute) and you have an expansive floorless tarp shelter.


Hilleberg should ditch their archaic clunky metal zipper pulls and replace them with two colors of reflective cord (one color on the inside, other color on the outside) and replace all the lines with reflective cord. We've wanted them to do this for years. Most other companies do… It would make the tent much easier to use and perhaps lighter, too.

Best Application and Value

Although the Nallo is a spectacular tent, our testers often reach for the company's Ajan or Nammatj more than the Nallo. We feel the Nallo's best application is extended international bicycle touring, where you occasionally cross a high pass and windy desert where the solid nylon interior and performance in high winds can be useful. We feel the tent is unnecessarily heavy for backpacking and not burly enough for winter use in mountains.

In the video below the tent could have been pitched with considerably more lengthwise tension, which would have reduced the flapping considerably.

I have the Nallo 2 GT (Nallo 2 with an extended vestibule) and have been a big fan.

Tent setup in stormy conditions is a snap. Lots of smart design features incorporated by Hilleberg to make things easy. Once setup, the number of inner tent and vestibule configurations make for an extremely versatile, strong shelter.

Two things are critical when setting up this tent in winter conditions:
  • Tie out all guy lines as far from the tent as possible. This is is important for the tunnel design's structural integrity regarding both load (snow) and wind.
  • Ventilation took a bit of getting used to. It's important to keep the bottom vent open in addition to the top to allow for proper air circulation. I contacted Hilleberg about this and they provided a fantastic explanation that righted my misuse.

If you're thinking of purchasing a Hilleberg, go to their website and request their annual catalog. It provides a ton of valuable info in an easily consumed format complete with fabric samples, specs and fancy pants awards received. They have great customer service and a hell of a product.

Good luck out there.

Bottom Line: Yes, I would recommend this product to a friend.

Really great review by OutdoorGearLab but I don't agree that the Nallo is in an awkward position between the lighter Anjan or the snow bearing Nammatj.

I use the Nallo 2GT predominantly in Scotland, and it totally excels in wet and stormy UK weather. Mine has seen some pretty horrendous storms - some of the worst were on Scottish islands in the summer. The high fly sheet on the Anjan would let in far too much spray for it to be comfortable spending much time inside.

For wet and stormy weather three quarters of the year with occasional snow use I think the Nallo has the right balance and versatility. I wouldn't feel as comfortable or confident in the Anjan.

One thing I would recommend trying is pitching the vestibule into the wind, as it improves ventilation and reduces the movement of the inner tent (especially the foot end) which makes it a lot more comfortable for sleeping.

Bottom Line: Yes, I would recommend this product to a friend.
