Strength/weight/space ratio: Nallo 2 with double poles

[Juho V]

Finally found the Hilleber Tent Thread from this forum… should have obviously posted there. There were basically already discussed everything I’ve touched here. Recommendation of their tents seem to go to Kaitum 2. It weighs 3.2kg but has three poles supporting the sleeping area which is very large with straight walls and apparently excellent ventilation. Same tent has been recommended in winter camping forums in Finland as well. Kaitum 3 is a bit too much weight for us at 3.5kg. Whereas Kaitum 2 with the space it has it might be ok. It even has two vestibules.

I think the space would be fine for two persons.

2.9 m² on inner tent and 2x 1.2 m²/12.9 ft² vestibule area. Quite a bit. Other vestibule for cooking and other for “garage” or snow or whatever cool drinks.

Can anyone recommend using Easton carbon or cyclone poles on this one to shave of some weight? Also any pictures of the storm internal guylines (similar to Slingfin tents) would be cool.

Still interested at the First Arrow X. Three poles on sleeping area, beefy 11.1mm poles,

Floor area 2.97m², vestibule 0.831m²… interestingly Kaitum is about the same size in floor area and almost three times the vestibule space.

I think I need to go with the Kaitum 2.

Jon, I think you meant this video https://www.youtube.com/watch?v=rjNFKU27hpo

Surprisingly little change with double poling and infact as you said double guylines did quite the same which I quite cannot understand. Two benefits, I guess: having more pegs per pole and having the upper guyline on different lower angle towards the peg. Experimentation would be needed.

This would be interesting to see in a tunnel tent. For the Kaitum 2 it would be interesting to see for example a situation where the middle pole is 10mm and the first and the third are 9mm BUT with internal guy-lines added. And double guylines to the windside on all three poles.

Hilleberg answered to my mail but did not comment anything on what I asked. Just said that Nammatj 3GT is the perfect choice for 2 person winter camping. Which I tend to agree, if we have a sled. But if not, then it is way too bulky to carry on a backpack.

I noticed there was a discussion on Hilleberg Thread that the Kaitum has all three poles supporting the sleaping area. I had a look and yes it is like that over 2.2m of tent lenght. But it is more or less the same with the Nammatj 3GT, maybe even shorter lenght. It is just not only over the sleaping area. Some said the sleeping area pole distance would be 45 inches or 114cm. I’m not yet sure about that. It would be more or less the same as in the Kaitum.

Juho, I have a Kaitum 2. Where did you see about the ‘internal storm guy lines’? No such thing on my tent

[Juho V]

There’s nothing in the Hilleberg tents already there but Slingfin tents come with internal guylines on the foot end of the tents at least my Portal 2 as well as I’ve seen pictures of others. They connect the outer guyline connection point to the opposite side peg attachment point making it quite strong. I think in the Hilleberg Tent Thread there was discussion about it and also here: https://backpackinglight.com/forums/topic/53189/

For Kaitum it could be much easier to implement than for the Nallo at least it has straight walls front and back. But I’m not sure how it should be modded and if it is worth it. If someone has a nice way it could be cool to see!

Thanks for the pic! How have you liked it? Plenty strong? Space for two persons? Ventilation?

[George H]

Love the tent. Our go-to two person w dog tent for winter, or short shoulder season trips where we want comfort and space.

We sleep opposite, with each their vestibule. This maximizes the interior space and works better in winter

Having the vertical end walls far from frosty exterior walls at foot and head is key for keeping the sleeping bag dry and having space. Probably the best feature and the Kaitum is the only 2 person with this layout.

Dog is at the feet of the shortest person.

End vents are huge and can be left completely open with no mesh even.

Another pic, haha

Thanks George for the information and another incredible pic! Sounds exactly like I thought it would be.

Just sold my Nammatj 3GT! Next hopefully will be able to test Crux X2 Shadow SL (2350g) demo tent. It’s almost identical to the Nallo 2 in weight and space but should I guess in theory be stronger. Should be interesting!

I have a Jannu and been looking at the (100g more) Nammatj 3(not GT) for 2 plus a dog.  The problem I’ve had with the Jannu (top hat design) is the (only) vent has to be closed in blowing snow/rain.  This seals up the otter leaving no way of venting the tent.

I’m looking for a tent that has through venting that can be left open in +/-20mph conditions. The Nammatj is one. The Nallo isn’t on my list as I’ve seen the lower vent covered in snow.

[Juho V]

Yeah the Nammatj is a great tent and has great venting. The sloping rear wall can be a problem for a very tall person but I haven’t had issues with it. I’m 180cm.

Check Kaitum 3 also. Many prefer that one.

 

[John W T]

The Kaitum isn’t on the list. Two reasons are the small storm flap over the entrance zipper and no mesh to stop spindrift/mist on the outer vents.  There’s also the extra length/width needed for pitching.

I’d like the Nammajt 2GT but it’s 500G more which will turn into 1kg once the fabric is covered in water/ice.

[George H]

Interesting how priorities differ. Yours are storm flaps and mesh on vents ruling out the Kaitum; mine are non-sloping end walls and dual entry, both handy for keeping my 6’6″ bag drier and allowing opposite sleeping for two people, ruling out the Nammatj

[Juho V]

John, do you have more info on the storm flaps and the vents how both of these differ from the Nammatj’s? Is this a real problem? In the original post the guy had issues with Nallo vents. They let out water so that the whole tent was full of water in the end. But he was on a rain like pressure washer.

Asked from Exped Polaris some proof of their statement on their website saying the tent has endured countless expeditions. It is a bit small for two persons but for the weight it looks robust and wind resistant. This is their response:

“Unfortunately, we can no longer send you a link as the feedback on this tent was received a long time ago. The Polaris has been around for a long time in a similar form. It has been used extensively and with pleasure by Steff Siegrist, Thomas Huber (Huber Buom), Ole Zill, Cedric Hälen and so on. All on expeditions in extreme cold (Himalayas, Antarctica). There a single wall tent makes much sense.”

I’m not sure what this fabric is about – is this eVent fabric?

“VentAir vapor-permeable 3-layer laminate”

Some earlier discussion here: https://backpackinglight.com/forums/topic/6656/

I remember earlier asking from Exped what is the tear strength of this fabric but they didn’t have any answer. I’ve read somewhere that for example ToddTex fabric from the Bibler-tents would be much more tear resistant as for example some heavy duty Nylons let’s say for example the Kerlon-fabrics from Hilleberg. This was related to the ToddTex being 3-layer laminate. I haven’t tried ripping of my Gore-Tex 3 layer jacket but it feels very robust. Of course it depends on many factors on the laminate.
