OK, back to N Cal and finally got the time to put my finalists down after an intense work trip. I had read the entire thread and also read up on the Hilleberg models that would best fit our uses, and a) I've decided on a double wall tent, and b) I've narrowed it down to 3 Hilleberg tents, two dome (Jannu and Allak) and one tunnel (Nammatj), that are close in interior space and differ primarily in the fabric/pole weight and slightly differ in vestibule space. All 3 supposed to be quite strong and are close in weight. While I'm 6 ft tall, all 3 tents offer enough room for me to stretch out and to sit up.
I'd like any feedback in terms of handling snow loads, staying quiet in high winds and usable space (particularly slope of walls in the Jannu and Allak).
I'm leaning toward the Jannu (lighter version of Hilleberg Tarra and Saivo).
JANNU
-free standing dome, 3 poles crossing in 3 places
-40" H, 93" L, 57" W
-36.6 sq ft
-13 sq ft vestibule
-1 door
-6 lbs 3 oz. packed weight
-Lighter though still strong Kerlon 1200 fabric
-9 mm poles
Advantages: great combination of strength, lightweight and space. Generous width and length large enough to use for 3 in an emergency. Strong enough to handle snow loading. Probably quieter in high winds than tunnel design. Longer and wider than Allak, yet still high enough for me to sit up. Just about perfect for our all-around winter use, and I could see using it for 3 season higher altitude exposed camps.
NAMMATJ 3
-tunnel that has to be staked out
-42" H, 87" L, 64" W
-36.6 sq ft
-17.2 sq ft vestibule
-1 door
-6 lbs 13 oz. packed weight
-Heavier weight even stronger Kerlon 1800 fabric
-10 mm poles
Advantages: Heavier, stronger fabric and poles; while same area as Jannu, could offer more usable space because of tunnel design; slightly larger vestibule than Jannu with more usable space. Enough room for 3, slightly wider (though shorter in length) than Jannu.
ALLAK
-free standing dome, 3 poles crossing in 3 places
-42" H, 91" L, 51" W
-32.3 sq ft
-2 x 9.7 sq ft vestibule
-2 doors
-6 lbs 6 oz. packed weight
-Lighter though still strong Kerlon 1200 fabric
-9 mm poles
Advantages: While you sacrifice a little interior space compared with the Jannu and Nammatj, you gain an extra door and vestibule, which could make storing and sorting gear easier, and could allow you to use one vestibule for gear and the other for kitchen. As a dome with 3 poles crossing in 3 places, should handle snow loading and high wind very well.
Question 1 – With the Polar Research Station at McMurdo supplying its scientists with Nammatj 3s, I'm sure it's a solid winter tent. However, since it's a tunnel design presenting a horizontal top, I'm wondering – does it handle snow loads well, and how quiet is it in high winds?
Question 2 – How do the Jannu and Allak compare to the Nammatj in terms of usable space? Do the walls of the Jannu and Allak slope so much that usable space is much reduced? While a tunnel should have more vertical walls, the Jannu's walls don't appear to slope down so much that usable space is reduced much. I've got nowhere nearby to check one out.
Question 3 – Would you sacrifice a little interior space for another vestibule – in other words, would you prefer the Jannu's roomier interior design with its single vestible, or the Allak's double vestibule?
I'd like to note that I think the Kaitum is a great design and considered the Kaitum 3 (tunner with 42 sq ft, 2 x 13 sq ft vestibules, 6 lbs 13 oz. packaged weight) but I'm willing to sacrifice the Kaitum's extra space for a tent that can fit in a smaller area, remain quieter in high winds and handle snow loads without having to wake up and bang tent walls. For extra space in protected areas, I think the Kaitum will serve anyone very well. If we could pick up 2 winter tents now, the Kaitum 3 would probably be one of them. For a winter all-arounder, I'd stick with the Jannu, Nammatj or Allak.
Any advice on Hilleberg retailers with good prices? I'm going to try to get a discount on the tent by offering to buy this and some other winter gear at one retailer in exchange for a 20-25% discount, and perhaps combining the purchase with some other members of our Sierra Club winter group.
