Outdated Product
The three-person trekking tent by the brand Naturehike can be classified as an advanced option and is recommended for hiking enthusiasts who value minimal weight in their backpacks. The model is truly lightweight at 2.42 kg and also delights with compactness in its case (42x15x15 cm), with a volume of less than 9.5 liters, making it easy to find space for it in a fully packed hiking backpack. The frame consists of three aluminum poles with a thickness of 8.5 mm: they provide moderate weight, remarkable strength, exemplary environmental friendliness, and resistance to temperature fluctuations, as well as excellent wind resistance thanks to its relatively low height of 110 cm. The Naturehike Opalus UL III tent includes a sleeping area measuring 210 by 165 cm, idea...lly suited for a family with two adults and one child, as the width allowance is 5 cm less than the standard 60 cm per person. The tent has two entrances — a main one with a large vestibule measuring 140 cm and an auxiliary one (40 cm vestibule). Overall, there is enough space outside the sleeping area for backpacks, outerwear, and other gear. The inner layer is made of nylon mesh fabric, while the outer tarp is of denser, more durable nylon textile with a polyurethane coating, ensuring basic waterproofing of 1500 mm water column. The floor is even denser and better protected from moisture — up to 3000 mm. Notable features of the model include ventilation elements, a loop for a lantern, reflective guy lines, and internal pockets.

How to choose a tent for different usage scenarios?Let's figure out how to choose tourist tents for a hike, camping or expedition

Durable, Lightweight, Compact

The three-person Naturehike tent is an ultra-light solution of the UL class and belongs to the advanced price segment. Thanks to the aluminum frame and nylon materials, its weight is only 2.42 kg, which is lighter than many two-person counterparts. When folded, the model is also very convenient for transportation: the cover dimensions are 42x15x15 cm and the volume is about 9.5 liters, so it can easily fit in most modern hiking backpacks.

Three aluminum poles with a diameter of 8.5 mm form a tunnel "semi-barrel" structure for the Naturehike Opalus UL III. The low height — from 95 to 110 cm — positively affects wind resistance. The set also includes pegs and guy ropes, the latter featuring reflective elements.

Two Vestibules

The tent has two entrances, and each has a separate vestibule. The main one features good capacity for a trekking model: its length reaches 140 cm, and the usable area exceeds 2 m², allowing for cooking in adverse weather conditions if necessary. The second vestibule is noticeably more compact — 40 cm long, but it is sufficient for one or two backpacks.

The width of the sleeping area is 165 cm, meaning each person has 55 cm instead of the more usual 60 cm. The most suitable use is for a family with one child. Three average-sized adults may find it cramped inside, so they should arrange themselves head-to-toe. It’s also important to remember that the pursuit of minimal weight affected material waterproofing: while a 3000 mm waterproof rating for the base can be considered acceptable, the tent rating of 1500 mm seems rather modest. For this reason, the model is best suited for use in dry weather.
