Performance Appraisal of the Tarptent Moment

Given the popularity of tarptents, this test/review is obviously timely, and the article contains plenty of good data. However, and especially relative to the norm for reviews here, I found that data difficult to find.

The structure of the article is lacking; it wanders from topic to topic with little summary or connectedness, returning to topics previously covered with little explication. The presence of charts early in the article, and comparison to only one other tent are perhaps the most egregious examples, mostly because the necessity of the "performance appraisal" is not well explained, and the use of the Firstlight only is not explained in any way that approaches adequate.

I also think that 5 nights use is an inadequate test period. This may have caused and or aggravated the problem of coherence in the review.

Agree, 5 nights is not rally adequate. I would have liked to see it tested in more substantial winds and heavier rains…

But yeah, pretty much all Tarptents suffer condensation issues. Not my choice for the fourth season.

"At any rate, this is the tent I want to go with. The thing I like best about single-wall tents is that you can set them up in rain without getting the inside of the tent soaked, as you would with a double-wall tent."

Yes, but then it can rain inside on you.

"I like this tent a lot. I don't think any tent on the market, single-wall or double, is impervious to some amount of condensation – it's sort of the nature of the beast, I guess."

Double walled shelters with solid inner tents prevent the condensation from dropping on you. In addition, a solid or netted inner makes managing the condensation much easier keeping your sleeping bag, etc, dry.

One issue of this shape in single wall design is that you sleep with the fabric very close to your face and this area will accumulate a lot of condensation. The foot end does not allow much movement to prevent some touching of the sides of the shelter with your sleeping bag.

The BD Firstlight is listed at 3.3 lbs with a 9ft sq vestibule at $320.
That is not correct. The vestibule is an extra 21oz at an additional $135.
That is a total of $455 (about $20-30 less shopping around) at a total weight of 4.65lbs.

I've found the Easton Stakes easy to bend as well. However, they only seem to bend severely if they aren't in the ground all the way. From the picture in the article where the stake is visible it looks like the author didn't have it buried to the nail head.

Miraculously the heads haven't popped off of mine yet.

I haven't tried the Moment and will not as it has the same problem as my current Contrail…………..condensation. I love the Contrail but hate the condensation which despite all the recommended methods persists in 99% of occasions I use it.
I'm stii waiting for the holy grail…….an ultralight 4 season tent with no condensation problems…..it still doesn't exist!!

"I also thought that there is a solid covering you can zip up on the two ends, to enclose them in case of really bad weather."

Yes, there are triangular flaps that completely close the ends of the Moment tent. They are connected to one side of the tent and tie back to open the tent's ends, or secure to the far side of the tent with a hook-and-loop fastener to close off the tent's ends.

Here is a picture of my Tarptent Moment's interior. You can see the rolled-up triangular end-flap on the left side of the triangular opening.

Here is a picture of my Tarptent Moment with the optional lengthwise center-line pole and the triangular door closed.

"The thing I like best about single-wall tents is that you can set them up in rain without getting the inside of the tent soaked, as you would with a double-wall tent."

I confirm that the Tarptent Moment tent can be set up in a pounding downpour without the inside of the tent getting wet. I got completely soaked, but the inside of the tent remained completely dry. The way Henry Shires has designed the Moment's door, you can get into the tent without having your gear inside the tent get wet.

"Are there guy-out points on the tent so that it would withstand wind a little better?"

There are two additional standard factory-supplied guy-out loops located part of the way up the central pole's sleeve. You can see them as black loops on the yellow pole sleeve in pictures of the Tarptent. These lateral guy lines run in the same vertical plain as the central support pole (hoop). I consider the Moment to be a four-stake tent as supplied from the factory, with the two end stakes (mentioned in the review) and the two lateral guys. I find that the two lateral guy lines significantly steady the Moment in gusty winds. (Of course in still conditions just the two end stakes would certainly suffice.)

When I ordered my Moment tent I asked Henry Shires if he would please add four more guy-out loops to my tent, one to each of the centers of the four long sides of the tent. He did so. When the wind is really gusting I pull the rear side of the tent all the way down to the ground and then I put two more stakes into the upwind sides of the tent. (I tend to pitch my tent so the door side is downwind, but I'm open to suggestions as I am a Tarptent Moment tent newbie.) Just so my arithmetic is clear, my modified-at-the-factory Moment has a total of 8 guy-line attachment points: 2 at the ends; 2 from the central pole's sleeve; and four on the centers of each long side. Technically that is 6 stake points (2 ends, 4 sides) and 2 guy-line points (on the sleeve of the supporting pole). At this time I am using MSR Ground Hogs for all of my stakes. That may be overkill. It may be sufficient to use titanium shepherd hooks for the four sides.

This particular added loop is on the center of the bottom of the door.

I find this review a bit confusing. I'm not sure why the tent is compared to the BD First Light. The BD First Light uses waterproof, breathable material (Epic). This is an apples/oranges comparison. You may as well compare this tent to a double walled shelter.

Since condensation seemed to be the biggest issue, a better comparison would be with the latest Contrail. It isn't clear what steps were taken to minimize condensation. Did the author open the doors fully? Did he open the screen netting? If so, how did he deal with drafts and bugs? How did the efforts to minimize condensation (as just suggested) compare with the Contrail? If the author wrote something like "unlike the Contrail, when I opened the door to get better ventilation, the wind blew right on my face" or "unlike the Contrail, I couldn't get enough venting without opening the screen door" then I would find this review more helpful.

It also isn't clear to me, from the picture, how much room exists above the head, when the backpacker lies down. This too could add to condensation (breathing contributes quite a bit of condensation, so if the walls are close to the head, your may get a lot).

One more thing: It seems like most reviews that talk about storm worthiness just speculate. I can understand this, as who knows when a storm will occur. However, I can easily see how this can be tested (assuming you don't mind hurting your tent). Place a board on the top part of the bed of a pickup truck. Put the tent on top. Drive down a remote highway (with someone else behind a ways, with their hazards on) and see what happens. If a tent can withstand 40 MPH winds, it is pretty good (in my opinion). You could even put the tent on a rotating platter, thus mimicking swirling winds. If you are afraid of the state patrol, there are probably some closed tracks (for amateur racing) that could possibly be rented.

"It also isn't clear to me, from the picture, how much room exists above the head, when the backpacker lies down. This too could add to condensation (breathing contributes quite a bit of condensation, so if the walls are close to the head, your may get a lot)."

Exactly.

Isn't Henry coming out with a condensation 'curtain' for the Moment? If it covers the head area it should work really well.

"No photos of the Moment under 3 feet of wet snow, like the BPL review of the Akto (a few years ago)?"

There are two pictures of the Tarptent Moment tent under heavy snow load in this BPL thread:

"The thing I like best about single-wall tents is that you can set them up in rain without getting the inside of the tent soaked, as you would with a double-wall tent."

Not always. The Scarp pitches almost exactly the same way as the Moment, the only difference is the number of stakes that you need to nail down in the process. You CAN separate the inner and outer walls, but if you don't, they pitch as one unit, so the fly keeps the interior dry even if it's raining when you pitch it.
