    With time on my hands, I've been thinking about my ideal 2-person tent for high altitudes. Requirements are that it be good in wind, reasonable in rain, have a small footprint and be generally single skin but insect proof.
    I know that this tent won't suit everybody, particularly in that it's not good for sitting up in but that isn't important to us. But apart from that, does anybody have any feedback (apart from on my drawing skills) . Also, does anybody know if it would be possible to get this made? Tipik-tentes perhaps?

    So it's basically a pyramid but with viestibules (or an elongated Hex, if you prefer). The redlines are the groundsheet, which would be part of a mesh inner with the mesh sewn into the seams. There would be inverted T-zips on the inner at A and B.
    There would be waterproof zippers on the fly at A and B.

    You end up with not much head or footroom. room. Especially when winf bows in the end panels.
    Tarptent solved the issue by putting struts at opposite corners and skewing the inner.

    This is mine, a small footprint wind resistant coffin.
    A frame. One door. Pitchloc.
    I don't hang around in a tent much.

    Door panels.
    173.56cm down the zip side
    150.41 along the hem
    200.24 down the long corner seam.
    I'll leave you to work out the angles, but it'll be close trying to get them out of a single width of silnylon.
    Did you get your hands on the Mini2 knot mid yet?

    Unfortunately, they only do the Stratospire with the detachable inner and I want to avoid the two-pole design; we've got the Dirigo for that. I'm aware of the lack of head/foot room, but we're short enough that it should work. Incidentally, it gives more room than the Khufu.

    Nice to know that your calculations agree with mine (though mine were to more decimal places :cigar:)
    The Knot Mid is looking a long way in the future at this stage :arghh:

    You can't, TT have patented the pitchloc ;).
    Mine is designed to pitch with two 145cm poles in an A-frame. So there'd have to be some way to pass the poles through the inner netting.
    This would be a summer tent so we'd be spending very little time in it too.

    I am sure you could persuade one of the Asian manufacturing companies to make a prototype....but they'd probably want to make 300!

    I guess you could get an idea from Dan Durston's strategy?

    That seems pretty similar/same to what i've always believed would be my perfect tent, although unsure if you are using 2 or 1 poles in your design?

    For me a solid inner, DCF Notch with only one door and the opposite door/vestibule utilised as part of the inner, to give that wee bit more wiggle room would be the aim, i like having my bergan and stuff inside with me. I would like it as a two pole'r like the notch, but never having tried a one pole tent like the Altaplex, i would be willing to try it as long as it doesn't take away too much of that storage space room


    a tent is for sleeping in only, walk-sleep-walk-repeat

    Material for my single skin breathable low-hooped stealth tent is on its way. :D

    Pole pass at 2.23. I did try to paste with the timed location but the forum strips away the time stamp.

    Thanks for that. It makes me wonder whether it might be simpler just to have the poles on the inside of the inner.

    I did think about making the head and footpanels from three triangles and pulling out like the Dirigo to give more space but it adds complexity and would need extra pegs.

    To get the most volume under the fly I estimate you want a 45deg. angle on the fly at the head/foot end : the supporting pole.
    As the length (280) increases that pushes the pole height up ….. probably beyond what you want. If you reduce the pole height and the angle below 45deg then you decrease the useable space at each end. My Howff - The length I tried for was 265cm, and with 45deg - the pole is usually ~130cms (pitched low).

    Width of 120cms is narrow IMHO given you'll loose a lot of space at the sides/corners where the sides come down.
    Fix up a pole and some strings (maybe sheets too) in the measurements you propose and then go sit/lie/move around inside it - most informative :D.

    I shall definitely try with string first if there's ever the possibility that this is going to go ahead.
    As designed, the angle is 43 degrees so shouldn't be too bad. The 120cm width was dictated by the maximum I could go for with 145cm poles, without lowering the peak height below 130cm. But if I move the poles inside the inner, I could go a bit wider for the inner, or a bit higher for the peak. I'll have to consider that. We really don't need a wide inner as we use a double mat and quilt; it saves quite a bit of space.

    Thanks to everybody who's chipped in so far.

    Shame about the knot mid, it's pretty much the external dimensions you're looking for, though the inner is only 2.20m.
    If I'd used any more decimal places, I'd be rightly ridiculed for it. 4 thou' should be a tight enough tolerance for this job. :roflmao::roflmao:

    I think the Knot Mid is going to be fine. The vestibules are probably a little small but otherwise it's pretty close to what I want except it's double wall.

    Ah. My bad. Yes missed the lack of ridge. So even less room!

    A friend has a Khufu.
    He's 6' like me. But it always looks a tight fit.
    3/4 pitches it looks like a corner has lost space too extreme catenary cut. Think the ASTA mid (almost copy) is a little wider. I couldn't imagine 2 coping well in either really. No room for maneuver.

    "tent for high altitudes"

    Lightweight
    Spacious
    Strong

    Pick any two from three.

    Having viewed the video that @Lempo linked, I've realised I can bring the poles inside the inner, which means they're a little closer together. This means I can go higher. Also, thinking about your first point, I've shortened the tent a little.
    However, having drawn it out to scale I've been doubting the wisdom of the inner and outer being the same width, so I've widened the fly.
    Updated plans:

    We don't "maneuver" :angelic:
    Basically, we just need a one person tent with room for two to lie down (close). Bozena does all the tinkering and sorting while I prepare a meal, enjoy the sunset etc. In the morning, she packs everything up while I brew up several rounds of coffee, enjoy the sunrise etc.
