IntroductionCase file: Espri 2P
Multiple personality disorder is characterized by the presence of two or more distinct or split identities or personality states in a single individual. Espri 2P’s parents, Nemo Equipment, referred her to me for review. What I found was a traditional two-person double-wall tent with a trail weight of 3.74 pounds (1.7 kg) that thinks she is also a fast and light dry-weather tent that has a trail weight of 3.48 pounds (1.58 kg), and yet also a luxury/wet weather tent coming in at 4.27 pounds (1.94 kg) of trail weight.
Amazingly, I determined that Espri 2P IS all three tents. As Nemo has waived the Patient Privacy Act in this case, feel free to peruse my findings.

Design and Features
Top Left: The Nemo Espri uses clips to make set-up easy. The upper mesh walls make for great ventilation, while the lower solid nylon blocks ground level winds and blowing dirt, sand, or snow. Top Right: A wide door opens almost the entire front of the tent. There is room for two standard width sleeping pads. Bottom Left: Shown with the standard vestibule attached, the fly has curved sections removed from the sides and back to cut weight. Bottom Right: Even with the gear loft in place I have plenty of head room. Thanks for the T-shirt, Nemo!
While I enjoy having fun with the intro, I have to say that the Espri 2P, and its big sister the Espri 3P (not reviewed) are truly multiple tents in one package. Well, multiple vestibule treatments, to be honest.
The Espri uses a common X-ed crossing pole design. The poles are factory bent at the back to make it steeper at the rear of the tent to add room. The inner tent clips to the poles with a single DAC H-clip and fourteen pole clips. The body has a bathtub floor that's made of 30 denier polyurethane coated nylon. It would seem at first glance that Nemo expects the Espri to handle rains of biblical proportions as the “tub” part goes way up the sides of the tent as can be seen in the pictures. This is common to a few of their tents, more in just a second. (No, don’t skip forward... ) Above the side walls is no-see-um mesh for ventilation and weight reduction.
The Espri has a single front entry door that almost opens completely. For some reason, Nemo chose to start the zipper that opens the door eight inches (20 cm) away from the corner and end it a little bit up once it has made its journey around the opening. Personally I would like to see it start all the way to the side. Inside the tent we find a small hanging mesh storage pocket on the side wall, and looking up we find a pretty cool suspended gear loft. The loft slides up and down to either offer more space for storage or head room for sitting up. I have to admit that I was mainly soloing with the Espri, and while I played with it on one trip, I then took it off to save weight. Fortunately, that is quite easy to do.
Left: The Espri has a long gear loft that slides up and down in the center to let it be adjusted for head space and for the amount of storage space desired. It also removes completely if not needed. Top Right: A large protected hooded vent offers excellent ventilation and air movement. Bottom Right: The DAC Jake's Feet holds the end of the pole and the fly which clips on to the end of the foot.
The outer fly sits on top of the poles and we now see why the sides of the floor go up so high. Nemo has cut the fly down to save weight. Catenary curves are cut into the bottom of the fly. These arcs just come down over the mesh portions of the inner walls. Guy points at the center of the arcs allow the fly to be pulled out to allow ventilation and give strength. The fly can be clipped to the inner at the apex of the catenary curves. As this is tied into the guy point when the guy-lines are deployed it adds to the room inside the tent by pulling out the sides a bit. Nemo calls these volumizing vents. A very nice touch (which I wish more manufacturers would emulate) is the hooded vent at the top rear of the fly that allows air movement and draw. The vent is held open by a tensioned wire at the edge. It is not closable, something to consider in high wind conditions.
Last but certainly not least in the Espri’s case is the vestibule, or lack thereof. Nemo includes a 7.1-ounce (201-g) standard vestibule easily recognizable to those of us accustomed to front entry tents. The vestibule zips onto the fly running around the outside of the door track and snaps to the tent at the bottom and top center if so desired. Two stakes are used to pull it out, forming a small but adequate vestibule. The vestibule can be opened from either side or both sides at the same time.
In the case that a vestibule is not wanted or needed, Nemo sends a 4.5-ounce (128-g) solid door cover that zips on instead. It lets the weight of the vestibule be left behind but will still keep the inside dry should you be surprised by a freak storm.
The opposite end of the spectrum is taken care of too. Nemo offers an optional Trekking Pole vestibule that adds a whopping 17.6 square feet (1.0 m2) of protected space. This is quite welcome when sharing the tent with another, or when in bad weather conditions. The Trekking Pole vestibule attaches to the same zipper track as the others and requires one trekking pole for use, fitting into a reinforced pocket.
Both vestibules and the door cover have windows inserted, but to be quite honest they are not very useful for seeing out of. They do allow light inside a bit.
Shots of the Trekking Pole vestibule attached. It adds a lot of storage space and totally protects the inner tent’s opening in rain and snow. A single trekking pole is needed for use. Bottom Right: This picture from inside the tent shows the space, and the walls sagging a bit from two days of cold rain. I was able to re-tension them once I went outside.
Nemo (like many other tent makers) has chosen to use the Jakes Foot set-up from DAC, the pole people. This nylon foot is hooked to the tent body at the corners. The poles have a ball on the ends which snap into a spot in the middle of the foot. The fly has a hooking clip that attaches to the end of the foot.
The tent comes with a 2.4-ounce (68-g) stuff sack to hold everything. A 0.6-ounce (17-g) stake sack and 0.8-ounce (23-g) pole sack are included too.
Top (clockwise from top left corner): Tent body, fly, stuff sack, guylines, pole repair tube, stake sack, pole sack, door cover, standard vestibule, DAC J stakes, DAC poles. Bottom Left: Espri in stuff sack. There is a lot of free space inside the stuff sack, enough to easily take the Trekking Pole vestibule too. Bottom Right: The Trekking Pole vestibule does come with a stuff sack of its own.
Nemo has made some major changes to the materials to save weight and improve performance. For 2010, the mesh was given an optimized knit pattern to reduce weight by 9% and increase airflow for better breathability. The fly and floors have been given a high quality DWR treatment in addition to the regular coatings. The fly is rated to 1,500mm hydrostatic head and the floors are at 5,000mm. The first tent they sent me had a black nylon making up the lower walls. This was changed in the production tents to the lighter grey nylon seen in some of my pictures as I swapped as soon as they got the actual retail model available. (It was worth the wait as it just gave me more time to play with the Espri. What’s that about a deadline, Addie?)
Nemo Equipment was wonderful to work with for this review. I asked about the weather proofing and was answered by one of their techs who told me that the Espri was tested in a rain chamber for four hours, after which they made some changes to the size/length of the upper vent. Four hours? Dude, I put two days straight in the rain chamber of backpacking life - you know, San Diego County - with it.
This has been one of the wettest winter and springs I can remember in Southern California. The Espri has been subject to some pretty harsh conditions. The trip mentioned above saw me use it for a section of the Pacific Crest Trail near the border of California and Mexico. We spent the night before the three-day hike at Moreno Lake Park, and since we were going through it, we planned it as our next night. So we just left our stuff set up there for the day. It had started raining at 1:00 pm and rained solid on us the entire next day. The Espri held up wonderfully to all the rain. There was no leaks or splash back, something I had worried about with the high cut fly design. I used the trekking pole vestibule on that trip, as I knew I would want the extra space for cooking and putting boots on. The vestibule garnered a few comments, my favorite being, “Does your tent have a garage?”
I took it on a solo trip to San Jacinto State Park knowing that a big storm was hitting that day. I wanted to test a sleeping system and figured that the Espri could share the abuse. It was snowing before I even got up the mountain, and I had to set up the tent in falling snow at 9,000 feet (2900 m) elevation. Thankfully it went up quickly. I used the standard vestibule this time and dug a twelve-inch (25-cm) depression under the footprint of the vestibule. This makes it much easier to enter and exit, plus gives a nice place to sit with my feet out if trapped in the tent. Well, I was certainly trapped. It never stopped snowing and dropped between six to eight inches (15 to 20 cm) of new snow on top of the Espri and the eight feet (1.7 m) of previous snow that the tent was set up on. The Espri proved to be quite strong and shed the snow well. I banged the tent every so often to knock the snow off, not because I was worried about the structural integrity of the tent, just as I had nothing else to do (should have brought a book). The sides did start collapsing a bit as the snow dropped down to push against the walls. I needed to push it away at one point when I woke to think that I was living out The Pit and the Pendulum by Edgar Allen Poe. “Ahh, the walls are moving in.” Hmm, maybe this generation would relate to the trash compactor scene from Star Wars better.
The tent did very well with condensation considering what the conditions have been. In the snow I had zero condensation, even though I had to keep the vestibule door closed. I did have to cook dinner in the vestibule and had visions of calling BPL and Nemo to explain how I burned the tent down with my Trail DesignsTi-Tri. Once I cooked dinner and then ate the rehydrated, steaming freeze-dried dinner, the moisture level jumped up, never to go down again. Then when the storm broke after midnight the temperature plummeted to 13 F (-10 C) from a stable 21 F (-6 C) most the day and night. Suddenly I had massive condensation that formed and froze on everything.
Left: Even though I banged the snow off before I exited the tent, some would still drop into the opening of the inner tent, usually landing on my quilt that I forgot to move away first. Right: (To the tune of Winter Wonderland) In the winter we can pitch the Nemo, in the mountains with snow falling down. We can even cook inside the vestibule, praying “Dear God, don’t let it burn down”
I have enjoyed using the Espri over the past few months. It has impressed me with the way it shrugged off the rain and snow. When used in rain with the standard vestibule, it will get wet inside as the inner is not protected when the vestibule is opened. Every time I had to exit during a snow storm the snow would fall straight inside. This is the reason I took the big Trekking Pole vestibule when I knew I would be in multiple days of rain. I would want this optional vestibule along if using the Espri for two people also, just to have extra protected storage space.
The ventilation is very good. Along with the great hooded vent, Nemo has come up with a good ratio of mesh and solid material. I was thankful for the high walls on a windy night in Angeles National Forest. While the air was definitely blowing through the tent (keeping condensation to zero) the walls kept it from hitting my face as I lay wrapped in my quilt.
Nemo, like many manufacturers lately, has started using the DAC Jake's Feet corner anchoring system. I quite honestly prefer the grommet and Fastex buckle system of old. The Jake’s Feet forces me to get my hands in the snow and mud to attach or remove the fly, plus it makes it more difficult to remove the poles when breaking down alone. Of course this could just be the grumblings of an old dog that has to learn a new trick.
Nemo has itself a solid contender in the lighter weight backpacking market with this multi-use shelter. While not at the cutting edge of the top tier, it does stand above the middle of the pack.
Dare to Compare
Other single door tents that compare to the Espri are the Marmot Zonda and the MontBell Thunder Dome 2. The Thunder Dome uses an X-ed pole design like the Espri, while the Zonda a hubbed system with crossing poles to add volume. Both those tents use a side door placement. Personally, when using a single-door tent for multiple sleepers, I would rather it be in front so that the person sleeping by the door does not have to be crawled over.
While the Zonda has more room, the rest of the specs are very similar and all are within $11.00 in price. The Esprit has much better ventilation than the other two.
Of course there are many other lighter options out there. If you are willing to shell out $50.00 more and give up some interior volume the Big Agnes Fly Creek UL2 is 1.35 pounds (0.61 kg) lighter.
