Ultraleichter Sommer-Schlafsack mit kleinstem Packmaß und hohem Schlafkomfort
Mit einem Gewicht von 500 g und einem komprimierten Packmaß von 13 x 18 cm, also nur eine Hand voll, ist der "DownWool 2.0 Extreme Light "-Schlafsack der optimale Sommerschlafsack zum Trekken, Biken, Campen, auf der Hütte und für den Jakobsweg.
DownWool® 2.0 – die bessere Daune
Das Problem mit klassischer Daune: Feuchtigkeit & Überhitzung
Daune ist das leichteste und am besten isolierende Naturmaterial – dazu extrem gut komprimierbar. Doch klassische Daune hat Schwächen: sie verliert bei hoher Luftfeuchtigkeit ihre isolierende Wirkung und kann zu Überhitzung führen. Gerade für unterwegs bei wechselhaftem Klima ist das ein echtes Risiko für Komfort und Erholung. Genau hier setzt DownWool® an – die intelligente Weiterentwicklung der Daune. Die mehrfach ausgezeichneten DownWool®-Schlafsäcke sind einzigartig durchdacht und bieten Lösungen für genau diese Schwachstellen.
-
Wärmeleistung auch bei hoher Luftfeuchtigkeit
Im Gegensatz zu herkömmlicher Daune behält DownWool® selbst bei hoher Luftfeuchtigkeit seine isolierende Wirkung – und steigert sie sogar noch bis zu einem Drittel. DownWool® plustert sich auf und speichert so noch mehr Wärme. Selbst bei 90 % Luftfeuchtigkeit bleibt es angenehm warm – ideal für trockene und nasskalte Bedingungen. -
Effektiver Temperaturausgleich – kein Hitzestau, kein Frieren
Die innovative Füllung besteht aus 70 % RDS-zertifizierter Tierschutz-Daune und 30 % Wolle aus den Alpen – eine natürliche Kombination mit Hightech-Funktion. DownWool® reguliert aktiv die Temperatur, da es stets zur Hauttemperatur zurückstrebt. So wird Überhitzung verhindert und Auskühlen vermieden. Gleichzeitig nimmt es Feuchtigkeit auf und leitet sie nach außen. So entstehen ein angenehm trockenes Schlafklima und ein deutlich größerer Wohlfühl-Temperaturbereich – ideal bei wechselhaftem Wetter. -
Komfortabler Schnitt – mehr Bewegungsfreiheit, weniger Kälte
Für erholsamen Schlaf braucht der Körper Bewegungsfreiheit. Der ergonomische Schnitt der DownWool®-Schlafsäcke bietet genau das: Platz für Schlafpositionen wie Seitenlage oder für Drehen, selbst in Mumienform. Die etwas großzügigere Passform verhindert Kältebrücken, da die Füllung nicht komprimiert wird – für durchgehend angenehme Wärme und maximalen Schlafkomfort. - Beste Schlafqualität: Die natürliche klimaausgleichende Isolation trägt zu einem schnelleren Einschlafen, tieferen Durchschlafen und insgesamt längeren, erholsameren Schlaf bei.
- Und das Beste: leicht & kompakt. Zusätzlich zu ihrer hohen Funktionalität sind DownWool®-Schlafsäcke erstaunlich leicht und klein packbar – für mehr Platz im Rucksack und maximalen Komfort unterwegs.
- OEKO-TEX® STANDARD 100-zertifiziert: Jedes Teil an den Grüezi bag®-Produkten wurde auf Schadstoffe geprüft und ist damit unbedenklich für die menschliche Gesundheit.

A Brilliant, Emotional, and Unforgettable Sci-Fi Adventure
Format: Paperback
Project Hail Mary by Andy Weir is one of those rare novels that delivers everything you could want from science fiction: gripping suspense, fascinating science, humor, heart, and a genuinely moving story about survival and friendship.
The novel follows Ryland Grace, a middle school science teacher who wakes up alone on a spacecraft with no memory of who he is or why he’s there. As his memories slowly return, the stakes become clear: humanity is facing extinction, and he may be the only person who can stop it. The mystery unfolds at a perfect pace, blending high tension with moments of discovery that keep you turning the pages.
What makes this book stand out is how seamlessly it combines hard science with accessibility. Like the author’s earlier work, the scientific details feel authentic and well researched, but they never overwhelm the story. Instead, the problem-solving becomes the engine of the plot. Each obstacle feels real, and the solutions are both clever and satisfying.
The biggest surprise—and the emotional core of the novel—is the relationship that develops during the mission. Without giving anything away, it adds warmth, humor, and depth that elevate the story far beyond a typical survival thriller. By the end, the novel becomes less about science and more about courage, trust, and the willingness to sacrifice for others.
The pacing is excellent throughout, with a balance of suspense, humor, and heartfelt moments. If there’s a small drawback, it’s that some plot developments feel a bit convenient. But the strong characters and emotional payoff more than make up for it.
Overall, this is a must-read for fans of science fiction, space exploration, and anyone who enjoys smart, character-driven storytelling. It’s thrilling, funny, deeply human, and surprisingly emotional. I finished it feeling both entertained and uplifted. Highly recommended.

Proof that lightning strikes twice ... Weir has done it again!
Format: Hardcover
According to a 2003 article on the NASA website, "NASA-funded scientists have recently learned that cloud-to-ground lightning frequently strikes the ground in two or more places ..." and that the third and fourth strokes of a lightning flash will follow the same path as the second stroke. In other words, lightning DOES strike the same place twice.
But you don't need to search the web for this information. If you want proof that lightning strikes twice, just read Andy Weir's newest book, Project Hail Mary, and you'll see that Weir has created a giant sci-fi bestseller, in the same electric path as The Martian.
Ryland Grace has a puzzle on his hands. He wakes up without a clue as to where he is, but he seems to be alone except for a computer AI that was keeping him alive. Unfortunately it didn't seem to be doing the same for two others in his ... wherever he is ... as he notes the decayed corpses in their creches on the ... well, it's a ship. A space ship. And bit by bit Grace puts the pieces of the puzzle together.
An alien microbe has been discovered. Ryland Grace is brought on to the science team to learn more about the life form because Grace, currently a middle school science teacher, wrote papers about the notation that there does not need to be water to create life. Only in a biozone such as Earth's would water be needed, but other building blocks could be used in other systems.
The science community as a whole mocked Grace, which is why he left and went on to teach kids, but now, he may be the best suited to understand this new life form. And as he remembers more and more, he also remembers that this life form is feeding on the energy output of the sun, which is decreasing the energy that gets to Earth, which spells disaster - as in the end of all life as currently known - on Earth if something isn't done.
Scientists discover that Sol isn't the only star that is losing its energy output - likely due to the alien consumption, but that there is one star, in the center of all the known stars losing their energy, that remains constant with its output. In which case, the answer to the survival for Earth is likely found there, at Tau Ceti.
The world's best scientific minds come together (by force and coercion) to create a ship that can get to Tau Ceti in twelve years (using the alien microbe as fuel) with shuttle pods to bring back answers to how to save the planet, but for the crew, it's a one-way trip.
Knowing why he's there is only the first puzzle for Grace. Now he has to figure out how to save Earth. There's a very small window of time for him to discover the way to save the human race and get the answers sent back. Take too long and the shuttles will return to a dead planet.
This book is amazing.
Author Andy Weir brings us back to the magic that made The Martian so successful - an abandoned scientist trying to survive. But Ryland Grace's story is more complicated because he's not just trying to survive, but also help humanity survive.
There's lots and lots of science - which is part of Weir's writing signature - and there's also a really wonderful story.
It's hard for me to tell you just what I liked about this book because anything I write will be a spoiler and a huge part of the joy in this book is making the discoveries with Ryland Grace.
Grace is our main character, but through the liberal use of flashbacks, we have a full cast of characters - at least one quite important to the story. Everyone is unique and individual which makes it easy to read, but just as with The Martian, where Mark Watney's personality carries the story, Ryland Grace here is the smart-mouth, sometimes funny, obsessed scientist infusing his personal tastes into his discoveries. He's also quite smart - which is good since he will need his intellect to save all of humanity.
This is a page-turner. I did not want to put this book down. Neither did my 21 year old son who picked up my copy after I was well into it and finished it before I did. And days later he's still talking about how much he liked it and quoting sections of it to me at the dinner table.
I hope Ballantine Books will do a very large print run because this is going to be huge seller and you definitely don't want to miss out on the biggest thing to come out in 2021.
Looking for a good book? Project Hail Mary by Andy Weir is proof that lightning strikes twice as this has all the excitement and energy of Weir's debut novel, with a more complicated storyline that will hold the reader all the way to the end.

Excellent Hard Sci-Fi… Until the Politics Pull You Out
Format: Kindle
I was really excited to dive into Project Hail Mary. As a longtime Isaac Asimov fan, I’ve been craving fresh, modern hard science fiction that actually respects the science. This book delivered — at least for a while.
The author injects real science into the story in a way that’s both fun and fantastic. You don’t need to be an engineer to follow it; a solid high-school education is plenty. The concepts stretch your imagination without ever feeling impossible, and for the first chunk of the book I was hooked. I genuinely thought I’d found a new favorite author.
Then the jarring interruptions started.
Out of nowhere you get yanked out of the immersive sci-fi world by modern political pandering that feels completely unnecessary. A random parenthetical about Columbus “discovering an already inhabited world” when comparing something to the New World. Casual pronoun lectures. Characters selected or described by race and identity in ways that scream “check the boxes.” These moments don’t serve the story — they feel injected. Once you notice the author’s leanings, it becomes hard to unsee.
Each time it happens, the fantasy evaporates. It takes several chapters to sink back into the story… only for the next micro-lecture to pull you right back out.
Overall, I loved the writing, the hard science, and the imagination. It’s some of the best sci-fi I’ve read in years. I just wish the author had trusted the story instead of sneaking in real-world politics. It’s like eating the best meal of your life… and then finding a hair or two in it.
Strongly recommended for the sci-fi, with the above caveat.

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat.
It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.
