Thank you, Stuart, for these two postings, especially for the comprehensive summary of the competing virtues (and shortcomings) of the Allak, Kaitum and Nammatj families of tents.
I recognised your distinctive white wild goat icon from some other postings on various BPL threads that I had been perusing recently. At the moment I am re-reading some of those threads relating to shelters and to Hilleberg tents in particular, including the granddaddy of them all: Hilleberg Tent thread, started by Doug Smith in May 2012 and still going strong in July this year!
If I have followed that thread correctly I recall that you started with a Soulo (sold in 2013) and a Kaitum 3, then bought a Nammatj 2 (2013). You became unhappy with the Kaitum 3, after finding that it could not comfortably hold 3 adults due to the narrowness and low ceiling near the doors. You arranged with Hilleberg US to exchange the Kaitum 3 at reasonable cost for a Keron 3 in 2014.
So I am still considering the various attributes of these tents and trying to work out what features and properties are most important to me, and what are merely nice to have. All the while watching the weight and bulk! (And cost!)
Feedback from you, and Doug Smith, StephenM, Ben Wartman, and many other contributors to these threads, who own various Hilleberg models and have used them in various conditions, is a valuable resource for those like myself who have yet to commit to purchase and are keen to avoid a possible costly mistake.
As to the criteria you listed:
– Weight
Preferably about 3Kg or just over, unless the extra features are compelling enough to justify a little extra weight. Would not want to exceed 3.6 or 3.7Kg for 2P.
I could possibly save about 100 or 150g on the packed weights of the larger tents by substituting lighter pegs.
For example, the Nammatj 2GT uses 22 stakes and, as a Black label tent, comes with the fairly hefty Y-pegs at 16g each (according to the Hilleberg Accessories page.) The average weight could be reduced to say 10g or less by substituting some or all these pegs with lighter alternatives (V pegs, Ti nails or carbon tubes). So that might reduce total weight from 3.7 to 3.6Kg or less.
But the same scale of weight saving would not apply to the Allak as it has only 12 V-pegs (11g each).
– Footprint size
Not critical, but obviously the smaller the better for a given amount of useable interior space.
I can see that a Kaitum 2GT, which looks to be a very nice tent at the limit of my weight allowance, might sometimes be hard to site due to its total length, including the axial guy lines. However, only the 2.2m long inner tent needs to be over good flat ground, as the vestibules can be over rougher terrain – but not too rough or the pitching will be very uneven, the tent will flap in the wind and the vestibules will be less useful.
One reason I am drawn to the Allak is that it seems very compact. And being essentially symmetrical in design (including its radial set of 6 guy lines) it can easily be rotated on-site, before guying out, on the possibly sloping ground to get a good sleeping orientation (head level with or above feet), without the need to worry about aligning it with the wind direction, or fitting it into an awkwardly shaped space.
The Nammatj 2, likewise, is fairly compact.
– Interior space
All of the candidates are adequate for 2P, but admittedly some are more commodious than others, mainly due to steeper walls and more headroom over a larger area. For the extra 300g I would seriously consider the 3P variants (Kaitum 3, Nammatj 3) to give extra inside space for 2P, and to accommodate 3P – possibly a bit cramped – when needed.
– Vestibule space
The Allak seems to have plenty of space for its 2P. And the fact that each person has their own door and vestibule is a plus. I often need to get up during the night a few times, so this arrangement of doors minimises disturbance to partner’s sleep.
The only criticism I have read about the doors on the Allak is that if it is raining great care needs to be taken when going outside or coming back into the tent. You need to open the outside door from the bottom just enough to get in and out, without that door flapping back onto the inner door, thus wetting the side of the inner tent.
The standard versions of the Nammatj 2 or 3 has enough vestibule space, and the Kaitum has twice that, which is nice (at the cost of a much longer footprint)
I really like the extended GT vestibules, but they come at a considerable cost, financial and physical: extra footprint length and much extra weight (about 600g). I regard them as rather an indulgence for my needs, so would probably forego them to save weight. The 2GT variants of the Kaitum and Nammatj are at my weight limit (about 3.6Kg), but the 3GTs are far too heavy (at about 4Kg) for backpacking for 2P. When more vestibule space is needed, say while cooking or organising gear, one can unclip and roll back the front part of the inner tent to give more space. And when using the tent for car camping or whenever weight is less important, one can improvise a porch from a tarp sheet and poles, to give extra shade or shelter.
– Freestanding vs non
In itself this is not a big issue. Sure, it is nice to be able to move the already-erected Allak a few feet here or there, or to rotate it before guying it in its final position. But I would be as happy with a tunnel design, which is obviously not freestanding, and where you need to take a bit more care with positioning it before it is erected. As Roger C. and others have pointed out many times, ALL tents need tying down to resist wind loads.
– Wind resistance
This is of great importance to me, as I have been in a tent that collapsed and whose fly was ripped in a storm. I am prepared to pay a bit extra, in cash and weight, if need be for some extra security against wind damage.
Tunnel tents are best pitched with their axis parallel to the wind direction. But wind can change direction overnight. Also, the constraints of an available site might contradict that imperative. In small clearings or on uneven rocky slabs the available clear space or the slope of the land may force you to orientate the tunnel tent more or less at right-angles to the wind. This is less of a problem with a dome like the Allak, which would have equal wind resistance from any direction.
– Static snow load capability
Not important. So either a tunnel or dome shape is OK, in this regard. I am not sure how much I will be using the tent in very snowy conditions. But I am sure the tent will be OCCUPIED during any snow storms, not left standing unoccupied for days as a base camp. The occupants can dislodge any snow accumulation from time to time.
– Ventilation
Very important. That is why I have already ruled out the Nallo tents, in spite of their toughness and tempting low weight. (The Anjan family is even lighter, but venting is not a problem as the fly does not touch the ground.) Likewise, the Jannu seems an ideal and cosy tent for the cold mountain air but less suited for valley camping on hot Summer nights.
The Kaitum is probably the most efficient ventilation machine, but I am sure the Allak would be good too. (On very warm, still nights one can lie with ones head next to the open inner doors, rather than next to the solid fabric, to get fresh air and take advantage of the slightest breeze.)
I am a little doubtful about the venting in the Nammatj in Summer conditions, especially on hot still nights. From reading reports by users, I feel that with all the vents open there is sufficient ventilation to prevent or minimise condensation problems, but there may not be sufficient air throughput to keep temperatures bearable on very hot nights or sunny days.
– Views of the great outdoors
Both the Allak and the Kaitum seem to offer good views under ideal conditions; when it is warm enough to open the doors and/or fold up the vestibule flysheets.
The Nammatj less so: its focus is more inward looking – secure cosiness, separate from the possibly harsh outdoors, rather than the easy indoor/outdoor flow of the Kaitum and Allak. The difference between an ideal Winter tent / Summer tent.
I will post again when I have some questions to ask about specific models, or when I am closer to making up my mind.
Thank you and best wishes.
