William, thank you for the suggestion. That tent was actually on my radar and is nearly what I think might work best. Compared to a purely rectangular pyramid like a Duomid or Khufu, this one by Knot, aka Aricxi, aka Ice River, aka Glacier Knot (formerly at ice-river.com) does have stretched out sides that offer a little vestibule space on either side. The inner that comes with it is 120 cm wide, which I know is too narrow. One possibility with this one would be modify that inner so that it occupies the triangular space on one side. This would provide enough space for the dog and leave the other vestibule unoccupied. Not sure I’m up to the modification. The other option would be to use it with a wider inner by Locus Gear or MLD, and I think they both would fit and offer enough width for us, but then the vestibule space would be used up, and with it any possibility of a dry entry.
I actually have three tents by this company, a hexgonal pyramid, an octagonal pyramid offering about the same space as a Supermid, and a small, one-man mid that is designed for pitching with A-framed trekking poles without needing any hardware. All these flys pitch very tight with little fuss, which I attribute to the designs accounting very well for the bias stretch of silnylon. According to a couple folks at trek-lite.com, Knot/Aricxi have recently improved their silnylon, which formerly was pretty lightly coated. I’m still considering various inners for the hex and octagonal pyramid flies for 1+dog use, but no combination gets me quite light enough.
John, thanks so much for your detailed reply and suggestions. I’m very sorry to hear about your dog.
If my dog did not hunt insects through no-seeum, I think the Rainbow Li would be the one for us. I’ve also looked hard at the Hornet 2p but think the inner would be a little narrow. I’ve found that 50 inches is the minimal width that would work. Not that all of the inner has to be that wide, but at least a portion. I would actually prefer a dome, as I don’t use poles that often and greatly appreciate the quick and easy pitch of a “pop up.” As you say, the footprint size is usually smaller too.
Alas, due to the insect issue, I think I’m stuck in the land of mids, which would be no problem at all but that we have either heavy mosquito or heavy tick pressure for three seasons here, so an inner is required. I would really like 2 pound outer + inner and don’t think there is anything that ticks all the boxes on the market. I’m mulling bonding up a custom DCF elongated hexagon or octagon (like the Knot/Aricxi but with wider vestibule sections, and with an asymmetrical inner that leaves one vestibule empty, allowing for a dry entry/exit). The making of the custom inner is the crux of that project, though, as I’ve not sewn.
