In deed it is a 3 season tent. but it is a BlackDiamond tent!
I use the tent with 12 guylines on a 85km/p wind and have ice rain. and it held like a big one for 13h!!!

Lowe weight and good 2 person size...you cant go worng

All in all I am very pleased with Mesa's performance to date, however I do find it takes up some real estate in my pack and the vestibules are on the small side for me

Pros:
Ease of pitch
Spaciousness of the interior
Does not leak

Cons:
Vestibules are too small in my view. I would like to see them being able to be pegged out about 100 mm (4 in) further from the inner.
Pole stuff sack is too small for the poles.
Packed size or rather packed shaped when using the supplied stuff sack.
The ease with which I was able to rip the stuff the sack.

After research and frustration with my MSR Hubba Hubba's lack of ventilation I found this tent. While slightly heavier that some of the other 'super-lights', the awesome design is well worth it. Great ventilation (one on each vestibule). Packs down well, I usually split up the tent between two people, into two of the smallest OR compression sacks (no problems getting the fly compress like one other user). Vestibules are an appropriate size to store our gear and keep it from the rain. This tent has been around the world and is great in inclement weather as well as in hotter more arid climates. Get a few extra stakes and a gear loft to supplement.

No one will ever complain about a lack of space in this tent. After years of cramming myself into my REI Quarterdome, I went with this tent for kayaking trips where weight or bulk was not so much of a concern.

At just over 5 lbs, the tent is still within backpacking range, though there are better comparable tents on the market for solely this purpose.

My big complaint is the rain fly. It is stubborn to get on. Once on, it takes a lot of work to properly align it. Little velcro tabs are available to help you with this, but I think the designers could have done a better job of it. (i.e., like providing tabs for the poles that are located over the entryways.) In addition to this, the vestibules are sparse for space. If BD were to address these two issues, I would ask that they also consider looking at the ventilation again. There is room to improve. REI's quarterdome has a top vent that is really handy.

Just got this tent and took it out to J tree to test it out. Feels very spacious even with my 110lb german shepard, climbing gear and I all inside at night. Build quality is what I have come to expect from Black Diamond and is excellent! Comes with great stakes that resemble msr stakes. Although the tent is a little on the heavy side when compared to newer tents. I would feel very confident taking this into moderate weather conditions if I had too. I can't say the same for the Big Agnes speedhouse sl2 and copper spur tents I tried out prior to this one. Although the two big agnes tents were lighter. Their pole design was just to delicate for me to trust in anything but perfect weather. I had them fail in 35-45mph winds when the wishbone pole got inverted on itself and turned my tent into a flat kite. If your like me and need a single tent to do everything short of extreme 4 season alpine adventures. Check this tent out!

This tent was raved about when I sold camping equipment. Everyone I talked to about it said that it was one fo the best tents they they have ever owned. Im planning on buying something like this tent but for those of you who arent sure if they want it or not it would be a great idea to get it

Just spent 5 nights in this tent in all types of weather. Great overall tent.

Location: Daisetsuzan National Park, Hokkaido, Japan

A Tropical Storm brushed Hokkaido while I was backpacking. I staked her down, but could only use 2 guylines, and then hoped for the best. What ensued was hours upon hours of mid-strength wind gusts, and torrential rain.Inside was essentially 100% dry. In one spot, the floor changed color, but was not wet to the touch. I assume some water had pooled between the tarp and my tent, but was not passing through the floor material. As for wind, I felt a few times during that night she would come apart under the wind pressure, but remained rock solid, with the main hub only moving a couple inches. Lost one fly staking due to sodden ground, but that was my fault for not tying her down beforehand.

After the storm, the day temps were 85+ F, and nights 65+ F. It revealed decent, but not fantastic, ventilation. Leaving the top part of the vestibule zips open helps a lot.She survived a brushing with a Tropical Storm, and can handle a respectable temp well. This was my first use, but I think it was a solid test to understand what this thing is capable of...Only complaint is that while the mesa is not a heavy tent, I still wish it was lighter. But hey, you cannot have everything.

This tent is really amazing. With the one-pole hub design, takes less than a minute to set this tent up! Packs pretty light and is the most user friendly tent I have owned. Took this tent on a 5-day trip to Zion NP and it was excellent through several days of thunder storms and heavy rain and wind gusts of 40-50 mph. The only thing I would have liked were a couple extra stakes. The tent comes with just enough to stake it down, but the featherlight aluminum breaks fairly easily. No major concerns with this tent. Awesome!!!

I used this tent a philmont scout ranch this past summer for a 10 day back packing trip. It went thru rain hail the size of marbels and nice days. The hail was so bad the ground had at least 2 inch coveing it with no sight of the dirt. It is easy to set up and take down. I would suggest buying the foot print that fits. Plenty of room for two large adults if needed.

Price is high but a good tent is worth it.

Great tent overall, easy to set up, easy to pack, light to carry.

Plenty of room inside for 2, a lot of room in the vestibules for wet & smelly gear. Slides of tent and vestibule open in opposite directions, a nice touch.

Spent 3 nights in Oshkosh during the airshow and have tested airplane blast on the tent, it did not move an inch.

The colour makes it easy to spot in the woods or in a crowded lot, but is not too flashy.

Got this tent almost a year ago now and have done some wonderful camping in it. Ranging from windy desert to summer nights on a glacier, this tent has been amazing. It's incredibly lightweight but still durable and so far, holds its own against rain like a charm!
Even slept three people in it on one occasion.

I used this tent all throughout Africa and it held up great. I was in some all night rain storms and only had minor condensation. Room enough for two buts its definitely tight. The length is great! If your short your bag goes behind your head. If your really tall, plenty of head room. I don't really like the orange vestibule. It stands out to much and I felt like it attracted bugs. There is also not much ventilation in the vestibule, so it can get really hot inside. Besides that, its light, easy to put up and take down, roomy, and compact. Best tent I have own for the size and weight.

I definitely pushed this one into the 3rd season and it performed quite well, very simple design too.

I love this tent. It is ridiculously easy to set up (impress your buddies with the way the poles snap into place), weighs next to nothing and packs down smaller than a lot of sleeping pads. Inclement weather doesn't stand a chance against this thing. It's pretty cozy, so you might want to think twice before inviting your sweaty hiking companion to share it.

The black diamond mesa tent was well enjoyed the other day for winter camping. Very subtle design. one gripe I had is how the stake straps don't cinch down. Thats a problem if your using for winter camping because you can bury the anchor but its hard to dial it in with out the cinch.

The vestibules are great, plenty of room for cooking and all that good stuff. packs down very nice. the spider pole system is weird at first but makes total sense.

I used this on a trip to Fruita, unfortunately it rained for two days of the trip. This tent kept everything inside dry, even without a tarp/footprint underneath. Very easy to setup, take literally 2 minutes if you have set it up before. Just make sure you stake the rainfly down so that you get coverage over the entire tent. No issues that I can think of.

This tent is pretty fantastic. Its lightweight, SUPER easy to set up, and it vents really well. The single pole design is not only simple to set up, but is incredibly sturdy. I used it for a recent trip to Southern Utah, and while most other tents around were whipped around in the high winds, this puppy stayed stable. The only negative aspect of this tent is that some might find it a bit too "cozy" for 2 people with full gear.

Pros: Insanely quick and easy setup. The one-pole design is genius, convenient, and intuitive: clutch when you're doing a crash-course setup in the rain. Packs quick, small, and light.

Cons: 2-person? It's more like a 1-and-3/4-person tent. But if you're willing to get cozy, have at it.

I had the pleasure to test this tent for a weekend and I'm going to agree with just about everyone else here, this tent is awesome. It's not the lightest but it's way not heavy. SUPER easy setup. Really nice in great weather under the stars without the fly. I'm a fan and will purchase this tent soon. Honestly, I get to test a lot of gear and usually find something bad to say about at least part of it, nothing bad to say about this tent I loved it.

So far I've only used it twice. I've unpacked and repacked it two or three times and I have to say over all its easy to do so even under less than perfect conditions. The outer shell is a bit difficult to repack because of stiff areas above the foyer openings. The Foyer is extremely small and for a person my size (6' 2") getting in and out of the tent can be a cramped endeavor. It kept me warm and dry through some pretty good thunderstorms and sleeping conditions were comfortable.
