Comparison with the old Jorasses backpack

A few notes for those who wonder how this compares against the old Jorasses backpack, which I have been a big fan of for Scottish winter. Overall this one falls short for me for several reasons 1- the buckles are tiny and have been significantly thinned down from the old pack. These are impossible to work with gloves on and are begging to break with a bit of rough handling. 2- gear leashes are flimsy and prone to breaking. 3- ice axe racking is poor. Jorasses pack was reinforced around the ice axe carrying area with strong and sturdy ice axe handle straps of a foolproof design. These ones are just fabric waiting to tear and have velcro (!!!!) Handle straps. Has anybody ever used this in snow?! You will not be able to lash the axes onto the bag once you put it down in snow! 4- waist strap is quite narrow and cuts into the hips. The older wide design is more comfortable. This is a pretty poor bag that is a pretty significant downgrade in terms of functionality. Can we please have the Jorasses bag back with a helmet carrier please?

Nice but some issues are killing it

I've just finished my 2 day walk with night in the tent in December Tatra mountains and here are my opinions: Pros - Very light and capacious, easy access to everything, versatile. Cons - Top flap is a DISASTER always ending at the back of rucksack if it's not completely full i was going to return it but I have managed to puncture the bottom and it is too late for that :( All is black, there is a problem to distinguish which plug should go where since there is so many of them, it is very problematic in frosty windy night. The plugs are very uncomfortable to plug and unplug in 90% cases i had to take of the gloves. The lowest eyelet where belt clipping two arms should go is to small so there is no way to thread the belt there. Socket to plug ice axe is very uncomfortably fixed to the body. Internal sling designed to keep rope at the top under top flap is super annoying since it always goes into zippier of the back access hatch, is is impossible to detach it, it is unnecessary since the rope can be keep by top flap. Hip-belt pads were fine for me, however the hooks could have some kind of protection against self unhooking as that happened to me twice. I don't believe that the bottom fabric will survive being frown on rocks several times even if it will survive the same with snow.

Brilliant! Simond should create larger version

Brilliant! Great value for money. Incredibly durable, versatile and lightweight. I believe Simond should also create larger versions of the "cliff" in 30 & 40 litre sizes. A back injury few years ago has made me extremely weight conscious and the lightness of this backpack combined with its great price was what made me purchase it in the first place. I'm in the look for a similar ultralight rucksack but they cost a fortune. If the " cliff" was also available in 30-40lt I would be over the moon! And would think of it as a great buy!

Functional design but can be improved

I like the zipper opening at the back. it works like a travel backpack. I also like the flexibility of add on and off some parts. However, I dont understand those cheaper version also used a more durable frabic at the bottom and back, why that does not appear in this more expensive backpack.

Batoh na hory.

Použitý při zimní turistice. Dobře sedí na zádech díky pevnému dílu, ramenní popruhy netlačí. Výborná věc jsou otevírací záda = rychlý přístup dovnitř. Materiál je lehký, odolný a příjemný na dotek. Kapsa na lavinovou výbavu je dostatečně velká, v létě ji možno použít na oddělení špinavých částí oblečení nebo výbavy. Na prsním páse ve sponě zapínání chybí píšťalka, pro případ nouze. Odnímatelné díly na bederním páse jsou uchycené plastovými háčky - často se samy odepínají. Nahradil bych je karabinkou. Samotný pás bych volil trochu širší. Zádový díl nad ramenními popruhy se samovolně ohýbá, bylo by vhodné ho vyztužit. Nemá to vliv na funkci ani pohodlí při nošení. Ve výsledku je to pěkný a funkční batoh, který se dobře nosí, hodně se do něj vleze a věci jsou v něm přehledné.

Alles super - bis auf die Hüftflossen

Für meinen Einsatzbereich (Skihochtour) war ich an sich sehr zufrieden mit Verarbeitung, Große, Schlaufen, Helmnetz, Materialschlaufen, etc. Leider ist jedoch die Hüftflossen nur in einer Schlaufe eingehakt und ich musste wirklich nach jedem Absetzen die Hüftflossen wieder einhaken - was mit dicken Handschuhen nicht immer leicht war. Hier wäre etwas Feintuning nochmals angebracht... Rückgabe bei der Decathlon Filiale lief absolut problemlos - daher großes Lob an euch: Ihr lebt den Service Gedanken!

Very thin and fragile buckle

The plastic buckle on the waist belt is very thin and fragile. It broke into pieces on my first tour

Lösung gegen das Aushängen der Hüftpolster

Ich bestätige, das das Aushängen der Hüftpolster sehr leicht geschiht. Das hätte man besser können. Etwas größere Polste wären auch nicht schlecht. Ich habe das Porblem gelöst, indem ich jeweils durch die Häkchenbefästigung eine 2mm Schnur geführt habe(mit doppelten Knoten gegen Verrutschen gesichert). Die zwei Enden weden dann zusätzlich zum Haken durch die Öse geführt und die beiden enden einmal uf jeder seite umgeschlagen und mit einer Schleife (Doppelknoten) gesichert. Bis jetzt funktioniert es.

Nur bedingt empfehlenswert

Ich habe den Rucksack bei einer alpinen 2-Tagestour getragen. Dabei war er suboptimal. Pro: - Die Möglichkeit, vom Rückenteil aus den direkten Zugriff auf alles zu bekommen, ist prima. Contra: - Die beiden seitlichen Polster der Hüftgurte haben sich regelmäßig ausgehängt, wenn ich den Rucksack abesetzt habe. Und im angezogenen Zustand brauchte ich Hilfe, um sie wieder eingehängt zu bekommen. - Und weil der Deckel voll abnehmbar ist, geht der Zug von den Brustgurten nicht auf die ganze Hülle, sondern nur auf das Rückenteil (mit dem Ergebnis, dass die Last nicht nahe am Rücken bleibt, sondern der Rucksack immer nach hinten wegkippt und sich der Rucksack innnen "aufzieht"). Mir (173 cm) ist es nicht gelungen, den Rucksack so einzustellen, dass er angenehm über die Hüfte zu tragen ist.

Super für Hike & Fly

...eine Susi3 mit 16 qm im 50/50 passt samt Hochtourenausrüstung perfekt rein. Dank der Rückenöffnung geht das komfortabel ohne Stopfen. Der Rucksack ist kompakt und einigermaßen leicht. Die Details sind durchdacht. Fairer Preis.

Buena mochila con fallos mejorables

Tengo esta mochila desde hace mas de un año y la he usado para travesías de varios días de esquí de montaña en condiciones frías. He cargado los esquis, crampones, piolets, casco en los lugares diseñados para ello. La mochila tiene muchos puntos fuertes, su ligereza, el acceso por la espaldera y su precio. Los fallos desde mi punto de vista son: tapa que no se queda en su sitio y si llueve se moja el interior o le entra nieve, aunque la mochila esté llena la tapa no ajusta y deja a la intemperie la tela de cierre interior. 2 Para las mujeres, los tirantes resultan muy abiertos y no se ajustan cómodamente a nuestra anatomía. 3 los cierres del cinturón y demás cierres son demasiado pequeños. es casi imposible abrocharla con los guantes puestos, ya que es una mochila técnica de alpinismo debería, al menos, poder abrirse y cerrarse y abrocharla a la cintura con guantes puestos y no es así. El cinturón es demasiado estrecho. Una mochila de este tamaño llena y cargada con esquís y piolets pesa y la tira de ajuste a la cintura es demasiado fina para que sea cómoda. Los bolsillos en el cinturón me parecen buena idea, pero no se mantienen sujetos en los ojales dispuestos para ello y no ayudan a que la cintura sea cómoda.

Motxilla Simond

Per fer esquí d'alta muntanya és ideal ja que té un compartiment per a cada objecte:piolet, grampons, arva...el més pràctic, però, és que tingui una obertura per la part de darrera, com si fos una maleta .

Buena mochila

La compré pero finalmente no se ajustaba a lo que necesitaba por el cinturón, vale que éste es desmontable y ligero, pero eso no evita que sea casi más un incordio más que otra cosa. Por ese precio me parece estupenda, pero yo necesitaba un cinturón que sirva de algo. La devolví.
