The Terra Nova website proudly states: “GUINNESS WORLD RECORD: The Laser Ultra 1 has been awarded the Guinness World Record for the lightest double-wall shelter in the world!” Well, I guess that gets our attention. The Laser Ultra 1 is a one-person double-wall tent with a manufacturer specified trail weight of 17.5 ounces (496 g), which is equivalent to the lightest single-wall tent I know of, the Gossamer Gear One. The Laser Ultra has a Cuben Fiber shell and floor, with a thin nylon fabric interior, and improved ventilation. Is this the Lamborghini of ultralight solo tents, or just the winner of a low weight contest?

Design and Features
The Laser Ultra 1 is as light as it gets for a one-person double-wall tent, with a measured trail weight of 19.7 ounces (558 g) and total weight of 20.7 ounces (587 g). The shell (and floor) is a very lightweight Cuben Fiber, which Terra Nova calls their “Ultra fabric.”
The tent includes 12 “1-gram titanium stakes,” which help to bring the weight down. I included a toothpick in the photo for comparison. Do you want to entrust a US$1000+ tent to these stakes? I don’t think so!
The 1-gram stakes readily pull out when the tent flaps, and are easy to lose, so the first thing I did was to replace the stakes with the lightest staking setup that I consider adequate, which is eight 6-inch (15-cm) titanium shepherd hook stakes, two Easton 6.25-inch (16-cm) tubular aluminum stakes (for the ends), and two guylines (for the main hoop pole). This adds 2 ounces (57 g) to the weight of the tent, bringing the trail weight up to 21.7 ounces (615 g) and total weight up to 22.7 ounces (644 g).
Views of the Terra Nova Laser Ultra 1: A side view (top left) shows that the Laser Ultra is a tunnel tent design with one hoop pole in the center. Each end (top right) has a vertical carbon fiber strut and four staking points. The top view (bottom left) shows the tent’s proportions. Looking inside the door (bottom right), there is large zippered entry into the nylon fabric liner. The top of the door is mesh, and there are mesh ventilation panels in the ends of the tent.
The tent interior has adequate floor space for one person plus gear, and gear in the vestibule can easily be reached from inside the tent.

The Laser Ultra 1 is easy to set up: insert the center hoop pole in its sleeve, stake one end guyline, stake the other end guyline, place three stakes at the base of the tent on both ends, stake the center pole guylines. Set-up takes only a couple of minutes. Since the tent floor is thin Cuben Fiber, a groundsheet is essential.
As mentioned above, I substituted some sturdy stakes for the 1-gram toothpicks supplied with the tent, and also added two center guylines, for a total of ten stakeout points. During my testing I experienced wind gusts to 35 mph (56 kph) and the tent handled it with ease. The tent did shake and flap quite a bit, which is noisy, but it’s always noisy when the wind blows.
I found the tent’s Cuben Fiber shell to be quite user-friendly. It stays flexible in cold temperatures and sheds snow and rain very well. I used a thin plastic groundsheet under the tent and did not incur any damage to the tent floor while camping in the backcountry. I chose smooth surfaces to pitch the tent on, but of course one can’t do that all the time. While I am comfortable with Cuben Fiber as an adequately durable tent canopy fabric, I am skeptical of using it for a tent floor. It does have higher puncture resistance than silnylon, and much higher tear resistance, but I would still expect the inevitable punctures and patches on the floor. In its favor, it is easy to patch Cuben Fiber with any kind of sticky tape, tape that does not stick to silnylon.
The Laser Ultra has a narrow entry vestibule (left) that is adequate for a smaller backpack. The tent has 34 inches (86 cm) of inside headroom at the center of the tent which is barely adequate (right). It gets down to where sleeping pad thickness makes a difference in how much I brush my head on the ceiling. For a shorter person, headroom is less of an issue.
My sample tent did not come with a hood for the center pole, but one is normally included to secure the tent and prevent leakage through the zipper. It rained several times while I was testing the tent and there was very little leakage through the zipper, so the hood is not really needed.
This graph shows the temperature inside and outside the tent on a cold late October night. In the early evening, the temperature inside the tent is colder than the outside temperature. I entered the tent at 10:10 pm, as shown by the left peak in the blue line. With me in the tent, the inside temperature stayed about 6 degrees warmer than the outside temperature. I got up to pee at 12:35 (the right peak in the blue line). The other two small bumps are when I turned over in my sleeping bag and pumped some warm air out.
A double-wall tent with a solid fabric interior retains heat at night, so it is warmer than a tent with a mesh interior or single-wall tent. I have measured a temperature difference of as much as 12 °F (7 °C) in a one-person tent, and 17 °F (9 °C) in a two-person tent, so a tent with a solid fabric interior like the Laser Ultra 1 is warmer at night.
Weather permitting, the tent’s entry door and ends can be raised “quarter open” to increase ventilation through the tent. This significantly reduces condensation inside the tent when there is nighttime air movement. However, on a clear calm night with a large temperature drop, as with any tent, there will be some, or a lot, of condensation inside the tent.
The following table compares the Terra Nova Laser Ultra 1 with alternative one-person shelters. Because the Laser Ultra is a unique high-end shelter, I compare it with alternative shelters of different types.
|Tent||Shell Fabric||Floor Area ft2 (m2)||Vestibule Area ft2 ( m2)||Ventilation||Mfr. Total Weight oz (g)||Cost (US$)|
|Terra Nova Laser Ultra 1||Cuben Fiber||16.7 (1.6)||3.8 (0.35)||Two end vents, door and ends can be raised “quarter open”||20.5 (581)||£650 (approx US$1048)|
|Terra Nova Laser Photon 1||Silnylon||17.4 (1.6)||8.4 (0.8)||Two end vents||27.8 (720)||£380 (approx US$618)|
|Hyperlite Mountain Gear Echo 1||Cuben Fiber||18 (1.7)||6.1 (0.6)||Mesh inner tent and large air space||23.7 (672)||495|
|Tarptent Moment||Silnylon||18 (1.7 )||6.6 (0.6)||Two top vents, two end vents, mesh perimeter||28.8 (810)||215|
|MontBell Crescent 1||Ripstop nylon||21.8 (2.0)||2.6 (0.24)||Two top vents plus partial mesh canopy||33.0 (936)||229|
|Mountain Laurel Designs SoloMid||Cuben Fiber||30.6 (2.8)||none||One top vent, open perimeter||9.0 (255)||340|
|Gossamer Gear One||Spinnaker Fabric||17.5 (1.6)||10.4 (1.0)||One top vent plus perimeter mesh||19.0 (539)||295|
- The Terra Nova Laser Ultra 1 is a limited production high-end tent, with a premium price tag; the Terra Nova Laser Photon 1 weighs 7.3 ounces (207 g) more and costs about US$430 less.
- The HMG Echo 1 shelter weighs 3.2 ounces (91 g) more, costs half as much as the Laser Ultra, has much better ventilation and versatility, but headroom is limited like the Laser Ultra.
- The Tarptent Moment is a single-wall tent similar in design to the Laser Ultra, weighs 8.3 ounces (235 g) more, has better ventilation, and costs one-fifth as much as the Laser Ultra.
- The MontBell Crescent 1 is a double-wall tent with a similar design, has more floor area, weighs 12.5 ounces (354 g) more, and costs about US$820 less than the Laser Ultra.
- The MLD SoloMid in Cuben Fiber is a floorless shelter with a lot more floor space, better ventilation, weighs 11.5 ounces (326 g) less, has loads of headroom, and costs one-third as much as the Laser Ultra, but it's not bugproof.
- The Gossamer Gear One weighs 1.5 ounces (43 g) less, has slightly less floor area (but it's all usable), nearly three times the vestibule area, better ventilation, and costs about US$750 less.
- Overall, every comparative shelter in the table beats the Laser Ultra in cost and matches it or exceeds it in other attributes.
Choosing the Terra Nova Laser Ultra 1 gives you the distinction of owning the lightest one-person single-wall tent in the world. Of course, you pay a premium for that privilege. When you consider the weight increment of adding adequate stakes and guylines, the weight advantage of the Laser Ultra diminishes.
While I am comfortable with the longevity of the Cuben Fiber canopy, I’m not sure that a Cuben Fiber tent floor is a good idea because it’s vulnerable to punctures and will likely end up with numerous patches. I would personally choose a floorless shelter rather than one with a Cuben Fiber floor, in which case the Mountain Laurel Designs SoloMid has a lot of appeal because of its much larger protected area, much greater headroom, and much lower cost. Interestingly, all the shelters in the table have limited headroom except the MLD SoloMid, and it has so much headroom that you can almost stand up in it. Alternatively, you can consider the Cuben Fiber floor sacrificial and patch it as much as needed, and it’s easy to patch.
Bottom line, the decision depends on what type of shelter you prefer and how much you are willing to spend. For a high-end ultralight tent, the Ultra is indeed the ultimate. But there are a number of alternative shelters that are also very lightweight and cost a lot less. Perhaps the significance of the Laser Ultra is that it maintains Terra Nova’s position as the manufacturer of the lightest tents in the world, and from our standpoint we admire their innovation and leadership.What’s Good
