I have been using the Seedhouse SL1 for about a year and a half now - it's been a busy year on the Work Front so I cannot say that I've used it as much as I would've liked but here are my views on this rather intriguing tent. It has seen 800m+ several times in the Brecons and Snowdonia, low-level (wet) camping in Norway and Sweden (cold as well) and the length of Hadrian's Wall two weeks ago. Firstly, for the space you get inside, given the weight, it really is rather good. It's well laid out for my tastes with the door at one end rather than in the middle. As it tapers towards the feet, I find that all my essential kit can be placed either side of my head at the front of the tent which maximises easy access. I tend to put my platypus, OMM Villain and boots in the porch and it swallows them well. I also use the footprint to protect the base - and this really is the crux of things. In order to be so light, the Seedhouse is made of very thin material and the inner, as Pete says, is mostly mesh. I would not want to pitch this without a footprint but I'm a little skittish about ripping the damned thing. Not having seen a Laser or similar tents, perhaps they are just as thin but it's something that I would want to keep an eye on. That said, the footprint is equally light and adds to the waterproofing of the base. In a very wet valley in Hadrian's Wall country, the rain pouring, I was dry as the proverbial bone. The mesh inner is not as cold as I would have expected. There is a small amount of wind-chill if the wind if really serious, but not if you pitch feet into the wind (as the design of the tent would tend to suggest - this is where the flysheet maximises wind-protection). Other than that, for an inner-mesh tent, it's pretty warm. It's been used down to 3 degrees so make your own judgments. I pack it in an Exped drybag with the pole(s) on the outside of my pack. I also have Vargo titanium tent pegs to reduce weight and they are great. All in all, a very good tent for balancing size, good shape and weight.
