Comparison Naturehike Cloud Peak II 20D vs Naturehike Cloud Peak II 15D

Seasons in which the use of a tent is allowed.

There are three main seasonality options: winter, spring / autumn and summer. At the same time, the design features necessary for comfortable use of the tent in different seasons are as follows:

— In winter, the tent should effectively protect against snow and wind, and its materials and fittings should normally endure a long stay in the cold. Thermal insulation is also desirable, but in general this is a secondary factor — the main insulation is provided primarily by clothing, a sleeping bag and a bed.
— In the off-season — in spring and autumn — protection from rain, which can be accompanied by strong winds, is of particular importance.
— For comfortable use in the summer heat, good ventilation is required, ideally with insect protection, such as mosquito nets.

As you can see, these requirements generally do not contradict each other and may well be combined in one product. Thus, there are very few tents on the market designed strictly for one season — two- or even all-season options are much more common. For example, even among beach tents (see "Purpose") there are models for which the possibility of using in the off-season is claimed — for this, the design provides for a dense awning, or even the ability to completely close the tent. Almost any model from the "spring-autumn" series...additionally has a summer specialization; and most models suitable for winter actually allow year-round use.

In conclusion, we recall that tents with the same seasonality and purpose can at the same time differ significantly in characteristics and design features.

The wind valve allows you to close the ventilation window to prevent snow or rain from getting inside. Its name is due to the fact that ventilation windows usually do not allow precipitation falling strictly vertically (in calm weather), but a strong wind can bring drops or snowflakes inside.

— External. The external frame is considered more convenient to set up, especially in the case of double-layer tents (see "Inner tent"), since both the inner tent and the outer awning are put on the frame at once. On the other hand, such a frame is more susceptible to the negative influence of natural conditions and does not allow the inner tent to be set up separately.

— Internal. The internal frame is somewhat more difficult to install than the external one; at the same time, it is less susceptible to the influence of unfavorable external conditions, and in double-layer tents (see "Inner tent") with an internal frame, it is usually possible to install only the inner tent, without an awning.

It should be noted that only tents in the shape of a hemisphere or half-barrel have a classic frame (see "Body shape"); in the case of gable tents, the characteristic "external/internal" refers primarily to the location of the supports, and the term "frame" is not applied at all to tent models.

— Inflatable. In such tents, the role of the frame is played by sealed hollow tubes made of flexible material (rubber or polymers), usually arched. When folded, they can be rolled up quite compactly, and when the tent is set up, they are inflated (usually with a special pump), acquiring the desired shape and sufficient rigidity to support the awning. The advantages of inflatable frames are their...light weight and ease of installation; they usually belong to quick-setup systems (see above for the latter). On the other hand, inflatable elements are very sensitive to damage: a small crack or hole, not critical for an element of a regular frame, disrupts the seal and makes the tent unusable.

— Pop-up. An automatic type of arc frame — it unfolds automatically when the tent is removed from the cover. This type of frame is often used in small budget tents, intended for those who prefer camping, nature trips and music festivals. Such tents are packed in a small round bag, which takes up a minimum of space in a car trunk or among the hand luggage of vacationers.

— PU (polyurethane). A polyurethane (PU) coating is applied to the inside of the outer tent. The protective layer of polyurethane increases the moisture resistance of the tent, at the same time, the strength of the awning fabric also increases. The main advantage of polyurethane is the ability to reliably protect seam joints. However, polyurethane protection is not the most effective, besides, the presence increases the weight of the tent. The use of polyurethane protection alone is more typical for entry-level (low-cost) class tents. In good quality tents, PU coating is complemented by other types of protection, often polyurethane is used together with silicone (Si).

— Si (silicone). The outer tent fabric is impregnated with silicone (Si). Silicone significantly increases the moisture resistance of the tent. The fabric impregnated with silicone acquires elasticity, its strength characteristics increase. This type of protection is considered the most technologically advanced and functional. The tent itself is impregnated with silicone (from the outside), and sometimes a PU coating is additionally made from the inside for better water resistance. The main disadvantage is the inability to protect seam joints. For this reason, the seams in silicone impregnated tents are glued separately.

An indicator that reflects the ability of the tent awning to withstand moisture without getting wet. It is expressed in millimetres of water column — the height of the water column that the awning can withstand (the area of impact is out of the question, because the load per unit area under water depends only on the height of the water column and is not related to the area of \u200b\u200bits base). The significant figures indicated in the characteristics (for example, 4000 mm of water column, i.e. 4 metres) are due to the fact that raindrops can have a significant speed and, when they hit the tent, create a load at the point of impact comparable to the pressure on depth of several metres.

In general, the higher the waterproof rating, the better the awning will cope with the effects of rain and snow. Indicators up to 3000 mm w.c. Art. are considered sufficient for places where it rains rarely, awnings for 3000 – 7000 mm of water. Art. allow you not to be afraid of intense downpours, and in expeditionary (see "Destination") tents designed for extreme conditions, this figure can reach 10,000 mm of water. Art. and even more. However, more water-resistant fabrics, usually, have a significant weight, so in each individual case it makes sense to choose the option that is optimal in terms of durability and weight.

Reinforced nodes in the design of the tent take on the resulting stress. So, reinforcements in the places of fastening of the arcs prevent the deformation of the load-bearing elements of the frame and prevent their destruction. Also, a lot of stress falls on the corners and seams of the tent awning when unfolded - the fabric in these places can tear due to high loads. The strength of such knots is increased by multi-layer sewing of the awning, the use of special fabric or additional firmware. A reinforced structure may have another weak point of the tent - attaching the awning to pegs (for example, eyelets). What specific knots are reinforced in the tent, you need to check with the seller of the goods in advance.
