What to choose — down or synthetic?

down featherPooh, by far, the best insulation to weight ratio — insulation. You have to understand that things are not "warm" you, and vice versa, and it can only be to reduce your heat loss. Heat loss, the smaller the thickness of the layer of air between the inner and outer walls of the sleeping bag. Recall the thermos, double glass windows, etc. So, down the least weight, filling the air and a specified amount — plus it first. That is why the down sleeping bags are so popular around the world. The second big plus — less than similar synthetic heater temperature, the size of a pack-packed sleeping bag. Third — down sleeping bags are usually pleasant to the touch, soft …. However, a lot depends on the fabric from which sewed sleeping. The older generation remembers tick "union" puffs and sleeping bags, heavy, like a concrete slab …. On his first seventhousander I, fearing the cold, lugging a sleeping bag, weighing 4.5 kg. Now such is not — and slavnenko … Fourth, substantial advantage — with proper care, if timely dry — down sleeping bags will last you much longer than synthetic.

Disadvantages when compared to synthetics, are as follows: First — down for needed care. Wet (from the overturned on him a pot of water from the river has fallen in a backpack, etc.) down sleeping bags does not function almost completely. And if anything like this happened to you, your sleeping bag may just dampen a night in a tent — to the tent of accumulated condensate from your own breathing. If the temperature is above freezing — it is nothing, but if it is lower — down gets frozen, and you are left with only light cloth cover — as a heat shield … To be honest, convincing … and dry it is not easy, but in the long harsh winter event — it is impossible. Unpleasant picture. The second big disadvantage — possible damage puhoderzhaschey tissue. Touched something sharp (cats, twigs, etc.) — and flew down … On the other hand — any good equipment necessary to care … do not beat you walkie hooks …


Sleeping bags with synthetic filling, in practice, it is best experienced external trouble than down. There are so many synthetic insulations — from «no name» to Primaloft One — better, in my opinion, synthetic insulation for sleeping bags. For those who never had the courage to make a choice between down and synthetic, some companies produce combined Pukhov and synthetic sleeping bags (for example, a series of Fusion Marmot). Now let's talk about the conditions when to use one or the other sleeping bag. Summer, easy short hike, hiking, mountaineering, climbing in simple alpine camp, leaving on a fishing trip, a May trip to the Crimea, a simple bicycle or boat trip, simple dry cave … In terms of price — the quality of the best will probably be sleeping bag with synthetic insulation «no name »and temperature control from 0 to +20 ° C … It is from 15 to 40 uev, heat will not even wet, do not mind to throw out, what if, etc. This is a plus.

Cons: too heavy (900-1300 g.), Take up much space in your backpack, usually no different original design. In short, miracles do not happen … Lightweight sleeping bag from a good brand synthetic (Polarguard Delta, Termolite Extreme) or feather from good producers will be significantly lighter (600-900gr.) And more pleasant to use, occupy a volume in the form of transport with a pair of fists — but and the price is 60-120 cu …. It is also clear that if the temperature is about 0 or higher — and bad weather, and you are not very experienced, or equipment not (tent, backpack, flow, etc.) — it's probably best to choose a synthetic …. Although it can be dried down — when it's good weather.

More complex activities — is thoughtful … Going to summer low mountains, climbing, average complexity, biking in the mountains — with temperatures at night to — 5.10 and a duration of action of 7-15 days … If a more important weight savings, and other equipment quality — better fluff. But if it is very wet — as in flooded caves, or in the mountains in bad weather, even if the bag leaks, or 3 person tent 5 people — and there is condensation car — steers synthetics … Talking about the expedition, we will see that and there is no agreement … However, in a serious event and people are skilled enough to decide that for them at any given time is more appropriate.

Then — just examples for thought …

Long winter ski and mountain hikes — usually large shared tent, stove, sleeping twin. Temperatures can range from +5 to -40 … condensate — a lot of it often saves a great cloak over all paired bags. It is called kondensatnik / kadavrik …. In such a throng keep down very hard — that's why the majority of tourists in favor of synthetics. As the case with the coaching staff in the tourist club alpklubah and, unfortunately, now the situation is not very good …. Yes, healthy conservatism …. Therefore, one can often see as a recommendation — and, buy parka, and all will be well …. And, in my opinion, it's not only equipment, but also the approach to the training process in general. We are engaged in tourism, in his youth, also has purchased synthetics …. And even leaving and going hiking to climbing, for a time were quite conservative. But worth a try competently handle down — and many others are already sleeping bags are not necessary … but now appeared bivuakzaki (bivouac sacks) — which will protect your sleeping bag from moisture in virtually any environment, weigh nothing, but still they can be used instead of individual stalls . As a result, the recent 3-5 day acclimation outputs while climbing our seventhousanders my backpack weighs 7-9 kg by well-chosen gear. And including — combined shortened sleeping (750gr) and bivuakzaka (450gr.). I often see tourists who die under his 25-pound bags — making a difference …
