Sensational
Light and small enough to fit my 2x Fuji GFX bodies and 2 lenses, yet comfortable to carry anywhere. Best bag Ive had yet

Prodotto molto valido per uso quotidiano
Ho sostituito il normale zainetto da città con questo ottimo e funzionale prodotto. Sembra robusto e contiene tutto il necessario già con l'ICU piccola e sottile: Olympus OM 1, 12-40 pro, 17 pro, 25 pro e 45 pro. Oltre a guanti, cappello, sciarpa, telefono documenti, occhiali e varie. Soddisfatto. Consigliabile.

Le même, en mieux.
J’étais un grand utilisateur du guru précédent (le bleu et le modèle UL). Ces modèles de sacs « type borne » sont très pratiques pour des sorties urbaines malgré ou grâce au petit volume du sac. Le guru 4 air garde une taille similaire et est modernisé avec les attributs de la série air. La différence principale qui saute aux yeux par rapport aux modèles précédents est la disparition de la ceinture. Mais comme contrairement à la plupart des sacs f-stop, l’armature en métal est absente, ce n’est pas très gênant. De plus, vu le volume du sac, ce n’est pas très grave. Je fermais très peu souvent la ceinture ventrale sur mes précédents guru, contrairement aux sacs plus gros. Le tissu Duradiamond rouge magma est magnifique et la nouvelle mousse aérée des bretelles et du dos est incroyable de confort. Les poches en façade sont extrêmement pratiques et cerise sur le gateau, les dimensions sont exactement celles d’un bagage cabine easyjet. Ce sac est une très belle mise à jour d’un modèle existant et qui en fait un sac toujours utile pour les voyages ou les sorties « légères ». Ma femme et ma sœur ont utilisé ce sac avec les bretelles en version "female" et ont été convaincues par le confort de portage.

Ottimo
Ho acquistato questo zaino per usarlo in aereo come bagaglio a mano, devo dire che e molto comodo , all' interno io ho messo una Sony a7iv, il 24/105 il 100/400 della Sony , il Tamron 17/218 il 10mm Voigtlander e il porta filtri della Nisi. Nella parte superiore ho messo due sacche con scatto remoto, e i kit pulizia obbiettivi. Devo dire che se era qualche centimetro più grande era meglio. Non l ho provato sotto la pioggia spero che sia resistente. L ho usato solamente appoggiandolo sulla neve , e mi sembra che non ci siano state infiltrazioni. E molto comodo da portare, considerando che avevo circa 7 kg di materiale non ho avuto problemi. Se ritornassi indietro forse comprerei il modello più grande.

Great every day camera bag/rucksack
Love this bag. It’s so hard to find the perfect bag. However this bag feels perfect for every day use as just a day rucksack for walks and one where I can carry a camera and a couple of lens, say for day hikes or travel (carry on bag) and just casual/opportunistic photos

My new favorite travel bag
Just what I was looking forWith the current airline restrictions I have had to convert to a rolling Hard side at pelican case just in case I get changed to a smaller airline or bumped down and class of seating. My current workflow is to use the hard case to travel through the airport and take theICU and place it in my suitcase with clothing and the external case easily fits in my suitcase are on my back and is easily tucked underneath the seat even on a smaller regional airline jet once at my destination, I use the bag to work out of in the pelican case as a transporter works quite well.

review Guru 4 AIR | 24L Adventure Modular Daypack
Its well made and looks good but my one major issue with this pack is the ease (or lack of) of accessing camera equipment inside. With the module inside you need to unzip both the bag and the module, and even then its unwieldy to pull out and put gear back in compared with other packs.
