Beschreibung des Kunstfaser Schlafsack für den Winter
Winterschlafsack für kalte Temperaturen
Der Winterschlafsack von Gipfelsport ist etwas für Kälteempfindliche. Dennoch kommt es auf den Einsatz an. Der Schlafsack garantiert bei einer durchschnittlich frierenden Person einen Komfortbereich von etwa 2 - 12°C.
Doch was heißt das genau? Der TComf (Komfortbereich) liegt bei diesem Modell bei 2°C. Das bedeutet, dass der Wert ein unterer Komfort-Grenzwert bei Standardgebrauch bei einer Norm-Frau ist - sie friert so gerade noch nicht. Je nach körperlicher Verfassung, können diese Werte etwas schwanken. Hier sollte immer ein gewisser Puffer eingeplant werden.
Im Allgemeinen gibt es vier Angaben für die Wärmeleistung eines Schlafsacks:
- Der obere Grenzbereich (Tmax): Dieser Wert gibt an, bei dem ein Norm-Mensch anfängt zu schwitzen. Dieser Wert wird so gut wie nie angegeben, da bei zu warmen Temperaturen, der Schlafsack geöffnet oder beiseite gelegt werden kann.
- Der Komfortbereich (Tcomf): Bei diesem Wert friert die Norm Frau noch so gerade nicht. Die Norm Frau ist 25 Jahre alt, wiegt 60kg und ist 1,6m groß.
-
Der untere Grenzbereich (Tlim): Bei diesem Wert friert der Norm Mann noch so gerade nicht. Der Norm Mann ist 25 Jahre alt, wiegt 70kg und ist 1,73m groß.
- Der extreme Bereich (Text): Dieser Wert sollte nicht erreicht werden. Hier geht es um das Überleben. Dieser Wert gibt an bei dem die Norm Frau noch überleben kann. Diese Temperaturen lassen sich nicht lange aushalten und es besteht die Gefahr der Unterkühlung.
Tipp beim Winterschlafsack Kauf
Wir empfehlen beim Kauf des Schlafsacks auf den Komfortbereich zu achten, da bei diesen Temperaturen sowohl Mann als auch Frau noch angenehm schlafen kann. Demenstprechend geben wir auch immer diesen Komfortbereich speziell an. Für diesen Winterschlafsack empfehlen wir eine Temperatur von 2 - 12°C. Dieser Bereich schwankt etwas. Je nach Statur, körperlicher Verfassung und Kälteempfinden kann dieser Bereich verschoben und/oder erweitert werden. So kann der Schlafsack auch bei einigen bis zum Gefrierpunkt (bis 0 Grad) noch erholsame Nächte bescheren. Der Schlafsack eignet sich bei wärmeren Tagen im Winter oder kälteren Nächten im Herbst und Frühling.Der Mumienschlafsack für längere Wärme
Der Schlafsack für den Winter hat eine eng an den Körper liegende Form. Der Mumienschlafsack ist die beliebteste Schlafsackform, da er die Wärme länger speichert als ein Deckenschlafsack. Durch die enge Form, ist auch weniger Material notwendig. Dadurch ist der Mumienschlafsack platzsparender als ein Deckenschlafsack. Der Nachteil eines Mumienschlafsacks ist, dass man in diesem weniger Bewegungsfreiheit hat. Auch kann man diesen nicht mit anderen Schlafsäcken am Reißverschluss kombinieren.
Vorteile des Mumienschlafsack
- geringeres Gewicht
- kleineres Packmaß
- höhere Wärmeleistung
Einsatzgebiet des Mumienschlafsacks
Der Winterschlafsack ist ein wichtiges Accesoire für alle, die im Winter oder sich in kalten Temperaturen aufhalten. Er ist besonders nützlich bei Aktivitäten, die mehrere Tage andauern können, wie Klettern, Wandern, Skifahren und andere Wintersportarten, aber auch für längere Reisen oder Campingausflüge. Der Winterschlafsack ist dafür konzipiert, den Träger bei kalten Temperaturen warm und behaglich zu halten. Dazu verfügt er eine besonders wärmende Füllung, die dafür sorgt, dass die Körperwärem entweichen kann. Sollte es dennoch zu warm im Schlafsack werden, kann durch den 2-Wege-Reißverschluss der Fußbereich geöffnet werden.

There is a war... for your Mind!
Format: Kindle
"There is a war... for your Mind!"
That's the slogan of InfoWars, the incendiary conspiracy news network and nutritional supplement marketing firm. And while Alex Jones is wrong about almost everything, he's right about that. In LikeWar Singer and Brooking ably synthesize a sophisticated picture of information warfare in 2018, drawing from sources as diverse as Taylor Swift, Donald Trump, and ISIS, to argue that the internet has lead to a blurring of lines between consumer, citizen, journalist, activist, and warrior which threatens the foundations of liberal democracy. The tech companies which built these platforms and profited from them must grapple with the politics of their technologies, before we all reap the whirlwind.
Computer networks and smart phones connect billions of people, allowing ideas to flow faster than ever before in history. Sometimes, the results can be impressive. The Chiapas Zapatista movement in 1994 was a dial-up and fax version of a network insurgency that managed to bring enough international opprobrium on Mexico that the government blinked, and reached some kind of political accord (Chiapas is complicated). More recently, Eliot Higgins and a team of open source analysts at Bellingcat managed to track down the exact BUK missile system and Russian soldiers responsible for shooting down MH 17 in 2014.
But there are a lot of dark sides. When people connect, the emotion that spreads most rapidly is anger. Lies spread five times faster than truth. Musicians can use social networks to directly connect with their fans, and ISIS uses it to connect with alienated Muslim youths worldwide. Social networks sort diverse citizens into filter bubbles of people who think alike. Eliot Higgin's careful open source intelligence has a paranoid fun-house mirror version in the QAnon conspiracy, where Qultist decoders find hidden messages from an alleged 'senior white house source'.
And then there is the matter of information war, an area that even now, after years of offensive cyber operations, liberal democracies still don't understand. Hostile propaganda slips into Western news networks and major platforms like Twitter, Facebook, and Instagram are infested with bots. LikeWar can even take a personal toll. Over the course of writing this book, General Michael Flynn went from forward looking full-spectrum commander to head Trumpist conspiracy cheerleader to indicted and plead out felon. Flynn's fall is complex, but it can't be separated from the internet. If the trolls got him, what chance does your idiot cousin stand? The counters, 'citizen truth teams' and senior emissaries to groups vulnerable to recruitment, seem like thin reeds against the coming maelstrom of noise.
LikeWar starts with Clausewitz's dictum that war is a continuation of politics by other means, and there are clear links between cyberspace and physical space. Intensity of hashtags impacted the subsequent intensity of Israeli airstrikes during attacks on the Gaza strip. ISIS used propaganda to create an aura of invincibility that outflanked the defenders of Mosul, while Russia denied that its 'little green men' were even in Ukraine. But the difference is that cyberspace is constructed space rather than natural space. The networks are built, maintained, and owned by real corporations and real people. The internet grew from an anarchic specialized scientific network to a major engine of commerce and communicate with little deliberate government oversight. Section 230 absolved American companies of responsibility for policing content, with major carve outs for copyrighted IP and pornography. Yet as concerns over cyberbullying and counter-terrorism rose, major networks adopted digital constitutions that were permissive towards speech and censorious towards erotica. Policing content is and was possible, but always took a back seat to growth and engagement, the guide stars of Silicon Valley.
The future is if anything, darker. Advances in machine learning and AI allow ever more realistic bots, computer generated DeepFakes where a politician can be programmed to say anything, and personalized targeting of people with exactly the propaganda they'll believe. There are defensive counters, but if I might draw military analogies, what we saw in 2016 was armored warfare circa 1918: clearly the future, but not yet a mature system. Given the pace of technology, we only have a few years before digital blitzkrieg.
I'm extremely online, and I've been following this space for years. I've presented at multiple conferences on this topic, including Governance of Emerging Technologies and Association of Internet Researchers. LikeWar is the book I wish I'd written. Cognizant, forward looking, and deeply researched, it is vital reading for anyone interested in technology or politics.
My only reservation is that I wish the sources were better linked in the text, instead of being buried in static endnotes. Maybe the next edition will push an update.

Making Sense of the Tactics Deployed in the Social Media War
Format: Hardcover
Singer and Brooking’s book, pulls together in one place the various threads of information about cyberthreats from the last few years, weaving them into a coherent, memorable, and understandable(!) whole. All these authors provide exhaustive lists of sources. It’s incumbent on responsible people to understand the tactics of information warfare, because, “[recent Senate hearings] showed that our leaders had little grasp on the greatest existential threat to American democracy,” said Leigh Giangreco in the Washington Post.
These ill-intentioned manipulators understand the human brain is hard-wired for certain reactions: to believe in conspiracy theories (“Obama isn’t an American”); to be gratified when we receive approval (“likes”!); to be drawn to views we agree with (“confirmation bias”). If we feel compelled to weigh in on some bit of propaganda or false information, social media algorithms see this attention and elevate the issue—“trending!”—so that our complaints only add to the virality of disinformation and lies. “Just as the internet has reshaped war, war is now radically reshaping the internet,” the authors say.
Contrary to the optimism of the Silicon Valley entrepreneurs who saw social media as a positive, democratizing force, this new technology is being used to destructive effect at many levels of society. At a local scale, for example, it bolsters gang violence in Chicago; at a national scale, it contributed to the election of fringe politicians; at a regional scale, it facilitated the emergence of ISIS; and at an international scale, it undergirds the reemergence of repressive political movements in many countries.
How to be a responsible citizen in this chaos? Like it or not, “we’re all part of this war,” the authors say, “and which side succeeds depends in large part on how much the rest of us learn to recognize this new warfare for what it is” and how ready we are for what comes next.

A Must-Read for the Internet Age (Even If It’s a Little Terrifying)
Format: Kindle
If you’ve ever found yourself doomscrolling through Twitter (sorry, X—ugh), arguing with a stranger in the comments section, or wondering why that ridiculous meme is suddenly everywhere, LikeWar is the book that explains why. And let me tell you, it does so in a way that’s as entertaining as it is unnerving.
P.W. Singer and Emerson T. Brooking take a deep dive into the battlefield of social media, where wars aren’t just fought with bullets but with hashtags, viral videos, and AI bots pretending to be real people (or worse, real people pretending to be bots). They connect dots between everything from military psy-ops to online disinformation campaigns, showing how social media has become the new frontline of modern warfare.
The book is packed with fascinating stories—from ISIS using social media to recruit followers like an influencer pushing protein powder, to political campaigns that make you question reality itself. And while the subject matter is serious, the authors keep things engaging with sharp writing, eye-opening insights, and just enough humor to keep you from spiraling into existential dread.
So why four stars instead of five? Well, while LikeWar is undeniably eye-opening, it occasionally gets a little too caught up in explaining things at length. Some sections feel a bit stretched, like that one friend who insists on telling a story with every single detail included. A tighter edit in some places might have made it even stronger.
That said, this book is a must-read for anyone who wants to understand how the internet shapes the real world—whether you’re a journalist, a policymaker, or just someone trying to figure out why your uncle keeps sharing weird conspiracy theories on Facebook. It’s insightful, timely, and slightly terrifying, but in the best way possible.

A Must Read That Belongs on Every Political, Social, or Military Strategist's Shelf
Format: Hardcover
LikeWar is the manual for warfare in the 21st century, a worthy successor to Singer's Ghost Fleet, and excellent debut work for Brooking. It belongs on the shelf of anyone who wants to seriously understand how war will be fought and social policy developed in the era of Facebook and Twitter.
There is a particularly urgent need for this book at a time when most tacticians have their eyes firmly fixed on enhancing cybersecurity through the protection of systems and hardware. While this is undeniably important, LikeWar reminds us that the information that is transmitted over that infrastructure is no less, and possibly quite a bit more important than the infrastructure itself. This message has never been more urgent than today when democratic nations struggle with balancing the need for an open civil society against the risks of foreign subversion and influence. This is the next great battle. It will be fought in the trenches of Facebook and the swamps of Twitter - wise commanders will bring LikeWar with them as field guide.
LikeWar stands out for its incredible scope and accessibility. Its coverage is comprehensive - everything from the 2016 election to the IDF's influence tactics are explored, analyzed, and fit into a comprehensive thesis about the changing face of war. Read LikeWar and you will have a confident grasp of the major developments in this new theater of combat. Yet the book remains eminently readable - this combat guide does not require a reader to slog through the bone-dry prose of a TRADOC manual or an academic paper. It is quick and engaging yet thorough at the same time.
In short, Singer and Brooking have written a manual for combat in the new millennium that is both engaging and substantial enough to leave their reader a master of the new face of battle.
