Since I took a camping trip to Zandvoort, in the Netherlands, by the North Sea, I am ever suspicious about camping equipment that promises to be waterproof. There I was sitting confidently in my no-name tent — which boasted a prominently placed and reassuring waterproof label — when it began to rain. It took exactly two-and-a-half minutes of a mediocre downpour until my shelter started leaking, and my gear and I were soaking wet.

Consequently, I put Mountain Hardware’s Trango 3.1 tent to my self-designed sprinkler test, first. I set it up on my lawn at home, programmed the irrigation system, crawled inside (clad in my raincoat, just in case) and let the automated watering unit do its job.

I watched the seams and zippers — every tent’s weakest points — closely. The water jets pounded the fabric, but not a single droplet made its way inside. The walls didn’t cave. The ventilation was excellent. Trango 3.1 scored.

Trango 3.1’s four-pole design with seven pole crossings offers maximum strength in winds and snow.

Trango 3.1 is guaranteed to be watertight, according to Mountain Hardwear’s Website. But don’t forget to read the small print — in your owner’s manual. If your tent will be subject to prolonged rainfall or a persistently wet environment, it says, certain points, such as where the sidewall meets the floor, require seam sealing with tape or liquid sealing products.

It will definitely be part of my next camping adventure to Canyonlands National Park, even though this is perhaps gear overkill, as Trango is part of Mountain Hardwear’s Expedition line, made to withstand the toughest alpine conditions. Not a lot of snowfall in the Utah desert these days.

Trango tents — available for two, three (Trango 3.1) and four persons — are specifically engineered for winter mountain environments, such as high winds and heavy snowfalls. They are extremely sturdy, featuring a patented tension shelf, for added strength, yet they are considerably light. Trango 3.1 weighs only about 11 pounds (5 kg).

The dome-shaped construction, which seems rather difficult to set up when you merely look at the illustration, needs just four poles to be taut and secure. (There is an additional, fifth, pole for the front vestibule area.) I intentionally chose not to look at the pitching instructions, and found the Trango 3.1 fairly easy to put up.

Even if you have to figure it out for the first time and are not the most practical of people, like me, the process is pretty self-explanatory. This is certainly not the case for other tents I have tried to set up, and which end up looking like collapsed soufflés.

The interior has just the right amount of space for the designated three people. Trango 3.1 has two two-layered doors, made of fabric and mesh. Besides the poled vestibule area in the front, there is an additional one in the back. If you need to keep the tent doors closed due to inclement weather, a mesh-and-fabric zippered vent provides good ventilation.

Thanks to a transparent plastic skylight, the interior is fairly light, even when using the tent’s rain fly. With 10 mesh storage pockets, some of them dual, there is plenty of room to stash flashlights, gloves, lighters and all the other small things you need to keep handy.

Many well-thought-out extras, such as external guy points, welded guy-clip anchors, snow anchors, reflective guy out-loops and zipper pulls, set Trango 3.1 apart from competitors’ products. When I tested the tent, the two-way zippers seemed to be running a bit rough at times; these could be smoothed out by frequent use.
