A new version of this shelter was recently released. Having owned both the High Route and the X-Mid, it shares a lot of the good features of those. The shape is a little funky but I think it works to save the long side walls from collapsing as much in the wind by creating more panels. If I am looking at the specs correctly if you don’t guy out the additional 7th and 8th stakes for those side walls, then the footprint is similar to the High Route, a long thin rectangle (102×38 vs 108×48). If you guy out one of them for a vestibule then it is (102×54). If you guy out both of them then it’s a similar wider footprint like the X-Mid (102×69 vs 100×65).

Some pros are:
- the overall weight for a double wall shelter,
- the ability to sleep straight in the offset pole structure,
- better potential wind stability on side walls than other similar tents,
- lots on internal living space.
Some cons would be:
- that the tarp sits high off the ground so less headroom if you want more storm protection (although this does help with the overall tarp weight and it is less of a concern when paired with high tub floor of the inner?),
- the large footprint when full guyed out,
- the fact you have to guy out with 6 stakes for it to reliably stand on its own (but who isn’t using 6-8 stakes on each pitch anyways?),
- asymmetrical pole instability in general.
I’ve been looking for a tarp to use with a ground sheet in non buggy conditions that isn’t tough for me to pitch (like a flat tarp), that isn’t too heavy (like my Dipole with struts 19.7oz), and that is more spacious than sloping walls of a mid. Even though the footprint is pretty big I like the weight (~14oz with seam seal) and livability of this shelter!
