Objektivität in Internet-Gear-Reviews??? (Am Beispiel Defence 4)

What is an objectively better sleeping bag? Perhaps you can use "objective" when it comes to the quality of workmanship (e.g., seams), but it's almost impossible to find truly terrible sleeping bags these days. In general, it's difficult to find poorly made outdoor gear... apart from cheap products. And even those are often quite usable these days. What's left is often: Do I like the product or not? If you want a second opinion before buying, it can only be: Does the person I trust like the product or not? Or rather, do many people like the product? Am I more convinced by the pros or cons? Questions upon questions! :-) The question of good gear always depends on many factors. Examples: Where are we going? And when? Winter? Summer? Rainy season? Where and how will we stay overnight? What does the route look like? Will I even be walking much? I've listed some of the alternatives to the Def 4 below. These are the parts I've found mentioned frequently in various forums, along with my own ideas. If anyone would like to add anything, please, I'd be happy to. :-) But I delete every stupid comment like the one at the beginning of the video: "There are objectively better ones!" YES, WHICH ONE? A comment like that is rubbish. It doesn't achieve anything except give the commenter the feeling that they've now "proven" they're a total genius who knows a lot about sleeping bags. Every now and then, I get warned not to expect so much from my commenters. I can't assume a certain level of education... That's true, of course. But with all the truly highly qualified comments I get, I also realize: Apart from a few outliers, it's perfectly possible to have a reasonable discussion. Even on the internet. List of possible alternative sleeping bags: (Important: These are not all my ideas, but opinions from the internet. Links are arbitrary and do not represent a recommendation for the respective shop or price.) Mammut Ajungilak Tyin Winter: https://www.asmc.de/Camping/Schlafen/... Although it's also weatherproof, it's significantly heavier than the Def. 4 and a bit more expensive. However, it's probably a bit to much warmer for most people. Mammut Ajungilak Kompakt Winter: https://www.globetrotter.de/shop/ajun... Probably not quite as warm as the Def. 4 (for suitable Def. 4 sleepers). However, it's heavier and apparently not water-resistant. Snugpak Softie 12 Ospray or Softie Elite 4 https://www.snugpak.com/military/mili... They're actually comparable to the Defence 4. Very similar temperature ratings in the military sleeping bag range. Similar shape, similar weight, wind/water-resistant material. The Defence 4 Elite is a bit narrower than the Defence 4, however, so it might be better suited for slightly slimmer people. What they don't have, however, is a front zipper, and I have no idea if there's a quick-release system. No front zipper can be good. Or bad. Depending on what you want. So, objectively, it's still not better or worse. I haven't tested them. Deuter Exosphere-8 http://www.doorout.com/Deuter-Exosphe... Here's the women's version. In any case, it's a little less warm, but very comfortable and fits pretty much everyone. Because: stretchy material. So if you absolutely want a sleeping bag with very few hollow spaces inside, this would be one. But it's also a bit heavier than the Def 4. I have it (previous model), and I like it. Mountain Hardwear Lamina Z-Torch https://www.globetrotter.de/shop/moun... It's a really good civilian sleeping bag with almost identical temperature ratings to the Def 4, BUT: According to EU standards. In other words, it's probably a bit warmer for most sleepers. And it's even a bit lighter... How come? Well. It just doesn't have a big zipper and it's cut a bit tighter, more of a mummy shape. You can't wear boots and a helmet in it. In my opinion, and for ME, this is THE synthetic sleeping bag for overnight camping in Norway, Sweden, or Scotland, for example, even if you're heading into the mountains. For bivouacking, I still like to use the Defence 4. However, I only slept in the Lamina for two nights and don't own one myself. In conclusion: For me, the Defence 4 is a good bivouac sleeping bag (not a bivouac sack). Because: It offers a good warmth-to-weight ratio, high weather resistance, and a quick-exit feature for wildlife encounters or people visiting.
