I am writing this review because when I had researched this tent I could hardly find any information on it. I have just received it and have not yet had a chance to really see what it can do as far as handling weather in a variety of conditions, but I thought I would write a little something based on my initial impressions since so little content is available for those who may be considering this tent.
Here are my initial impressions. The tent is light for a 2p tent, but not the lightest. However, for the weight is seems incredibly sturdy. The bent pole design is a very nice feature, and does in fact make the tent seem bigger than it actually is in terms of floor space (it does provide more actual space in terms of volume compared to a typical dome). The ceiling height is higher than I expected, a person six foot and under can comfortably sit straight up and lie down with plenty of room. If one were over six feet (and using the tent with two people) it would be a bit short. Nevertheless, for the average person this has plenty of space. The Nyx saves weight by making a bit shorter in length and narrower in width than the Aeolos. It also has only one smaller vestibule and door opposed to the two doors and vestibules on the Aeolos. All of this considered, the near one pound of weight saved between the two will probably make it well worth it (it does for me since I carry the whole thing). Further, for people of average, even slightly above average, build it is a very comfortable tent. I had also mentioned that it was sturdy. This is typical of Marmot, but what I didn’t expect (for a 2p tent under 5 pounds) was how bomb proof the rain fly would be! I think the fly makes up the majority of the weight, and is well worth the few extra ounces (compared to other manufactures and single wall tents) to have such a solid fly. The Nyx incorporates all of the features one needs in a well built, solid, and comfortable 2p tent. I hope this information helps anyone considering this tent as I am already very happy with the purchase and can’t wait for some very inclement weather to test this baby out in. The last selling point, of course, is the price. It is considerably less than the Aeolos, for good reason as the Aeolos is a bit bigger. But considering my own needs, the weight, and the price, the Nyx has won my vote hands down.

I picked this tent based on price, weight, and it's roominess. The poles do add usable room. It is simple to put up and pack. Coming from a 3/4 season 2 person tent, I honestly thought something was missing when I opened my shipment... very light.

I have even used this tent on a sheet of ice as a test (mid-April Breckenridge, stakes hammered into snow). It handled a windy night at 11,000 ft like a champ; obviously didn't keep a ton of warmth in at that time, but it is an excellent above-freezing tent. I plan on using this tent for years to come.

I have used the NYX as a solo tent for 2 seasons and have had no problems at all. I have camped in the Appalachians in heavy rain, sleet, moderate snow and very gusty wind (I can't seem to pick a weekend with great weather). The tent has never leaked, dripped, ripped, bent or swayed. Besides being bombproof, it is very spacious and comfortable. Setup is easy, and the weight is only 4-1/2 lbs. I'm an habitual tent trader, but I have no reason to look elsewhere for an outstanding lightweight tent.

Like the review above, I like this tent. I am 6 foot 6 inches tall. I share this tent with my wife and we sleep comfortably in it. One reason I bought the tent is 88 inch length which is longer that other 2P tents. The weight is also good especially when split between two people one person takes the body of the tent the other takes the poles and rainfly. We spent 16 hours in the rain with this tent with no problems whatsoever. Only drawback is single door opening at the head of the tent. I prefer doors on both sides myself. Besides that it was well worth the money. I will be looking for ultra light pole set to lower the weight a few more ounces. We already changed the tent stakes for a lighter set.

Dude. So easy to set up and take down. You'll have this thing up in under two minutes even if you are on your own. Stable in strong winds, great sky view w/o the fly, light and compact...couldn't ask for anything more. Plenty of room for two people and a medium sized dog and the vestibule ate up our packs. Stoked!

i bought this tent for its roominess and weight characteristics. its easy to set up and packs to reasonable size. vestibule is also large enough to encompass an 80 lb dog, which was key for me. the only draw back for me is not enough ventilation when rain fly is on. would be ok for western climate i think.
