Marmot Tungsten 1P or Hilleberg Soulo?
I know which tent I would rather spend a night on the fells in the Lake District. The Soulo! The Tungsten has a mesh inner does it not? Depending on where you pitch, this might not be suitable, where do you go hiking and climbing MT? In warmer climates?
Yes, it does have a mesh inner, which is precisely why it does not get issues with condensation on the inside, like you will have almost certainly experienced with your Soulo. In the morning you would have faced the frustration of having to wait around for the Sun to rise high enough to start drying out the condensation soaked interior of your Soulo, before you can finally put it away, whereas the mesh interior of my Tungsten will already be practically bone dry, allowing me to be packed away quicker, and on my way much sooner.
If you get impatient with how long the drying process is taking on your Soulo and decide to put it away when it's still damp, you will end up with a mouldy Soulo, whereas my Tungsten will still be mould free.
And no, it's not draughty inside, because the mesh, whilst being highly breathable, stops the wind coming through. It makes the Tungsten a warm, dry and pleasant place to be at night, even on a cold, windy, hill top.
The rain fly on my Tungsten is not ultralight Nylon, it's far more robust Polyester, which does not sag when it gets wet, and dries much faster. OK, it is a bit heavy for a backpacking tent, (still a couple of hundred grams lighter than Soulo though) but it's also built to last. It even comes with a footprint as standard (included in the weight), though for use on sheep-shawn grassland, this could be left at home, saving more weight.
