"Extrem robust, bis ca. 12 kg sehr gut zu tragen, 4 ausreichend große Taschen am Hüftgurt und Schultergurten. Leider sind die zwei Brustgurte so befestigt , dass sie herunterfallen (einer ist schon verschwunden) und die Lageverstellriemen lockern sich. Die Kompressionsschnüre sollten elastisch sein."
"Bin jetzt seit drei Wochen mit dem Betalight 45 unterwegs. Dabei sind mir zwei Sachen negativ aufgefallen, die mich bei einem Produkt dieser Preisklasse stören. Zum einen lösen sich immer wieder die zwei Brustgurte (vorwiegend links). D. h. man muss die kleinen schwarzen Dinger sehr oft suchen, einen habe ich schon verloren. Zum zweiten lockern sich immer wieder die Lageverstellriemen. Der Rucksack fällt sehr kurz aus, die Größe M ist mir fast zu klein, obwohl ich üblicherweise Gr. S oder M habe. Ansonsten ist er robust, funktionell und nach einer Eingewöhnung auch mit 12 kg gut zu tragen, wobei das dann fast die Grenze ist. Brustgurte hätte ich gerne, da ich noch weitere 5 Wochen in den Pyrenäen bin. Als Kundenservice einfach ein paar zu mir nach Hause schicken, das wäre doch ein Vorschlag."
"After some modifications nearly the perfect backpack. I am quite small (162 cm), female bodied and have average shoulder width for my size. Size S of the Backpack fits very good for me. I have a relatively short upper body and the hip belt pockets were extremely annoying for me. I touched them every step with my elbows when walking with trekking poles. Therefore I decided to cut them of. I wished the hip belt pockets would have been removable. I also wished the belt was sewn onto the padding of the hip belt. I left the back panels of the pockets attached to the hip belt to make sure the belt stays put. But in motion the padding is still moving (was already before I cut off the pockets). The load lifters are very nice and help carrying heavier weights (like longer water carries). But one of them on my pack is very slippery and keeps loosening itself every km or so. But I can live with that. I wished the pack had two water bottle pockets in the front to distribute the weight more evenly. Nonetheless I love the strap system which is like my running pack. The large mesh pocket ist awesome. You can stuff so much in it. The only think that annoys me about it is, that when the pack is very stuffed you nearly cannot access the pocket because the upper unstretchy part won't move a mm. The two large side pockets are awesome. They hold ab 2 L Water Carries each easily + extras like a buff and Sunscreen. The roll top closure is super nice. I wished that there would be 2 additional straps in the side pockets to buckle into to compress the pack a little bit more when stuffed. A Y shaped top strap would also be nicer imo. The last thing I would change are the straps attached to the pack. First of all I would use something like reflective tent cord or something similar, because it's lighter and more versatile. Secondly I would ad a zick zack style strapping on each side of the pack to help with compression of the stuff in the pack. All the stuff mentioned above I would still buy the pack again. Love it so far. Carries heavier weight super nice and is extremely comfortable. I hike casually on Weekend trips in Central Europe with it. And I also hiked the entire West Highland Way with it without any problems. My base weight ist with around 6 kg not ultralight and I can comfortably carry 7 days of food and 4. 5 L of water with this pack. Hoping for v 2 of the pack with a little bit improved hipbelt and two front pockets for water bottles. Everything else is just a nice to have."
"Sac incroyable, légèreté et robustesse au rendez vous, le confort de portage est excellent, utilisé pour faire le gr20 en corse et l'ascension de Mont blanc, je n'ai pas grand chose à redire sur ce sac. Les seuls points négatifs sont l'étanchéité, après de fortes pluies sur le gr20, l'eau à fini par s'infiltrer par le dos mais légèrement, deuxièmement, le tendeurs en plastique en dessous qui s'est cassé quand j'ai serré pour maintenir la tente."
"Amazing pack for short adventures. Very very comfortable under weight. On the go pockets not good enough. Refund is very slow, still waiting"
