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.

My new favorite travel bag

Just what I was looking for With 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.

f-stop

Hi Mark, Thanks for the feedback, but the insert is meant to be unzipped and the ICU lid tucked under it when it is in the pack, so you only unzip the back panel and have instant access to your gear.

It survived the rockies!

Comfortable, fits a surprising amount and is largely weatherproof. The only exception is the front pocket which has a fabric zip, so water egress is possible via that route, but my camera gear stayed perfectly dry. The small cube is big enough to fit a Canon R5M2, RF24-70 f2.8 and RF 70-200 f2.8 - making for a very small and travel friendly bag.

I couldn't ask for anything better for my macro outings and travelling light

I think the title already expresses everything I think about this backpack. The Guru Air has become my main backpack for macro photography trips. Small, easy to handle, and spacious enough to carry everything I need for this type of photography. I used to use my Ajna (which I love), but there was a lot of empty space inside the backpack, and having accessories in the top pocket made it sink into the inside of the backpack. Nothing serious, but inconvenient. The Guru Air has filled this inconvenience; everything is within easy reach. I equipped it with the medium-shallow ICU, and inside it I can fit my Z6 II with the Sigma 180 2.8 macro, a 24-70, lights, and extra batteries. Above the ICU, there's space for a t-shirt or a small pencil case (which can also be reached via the top zips). What else can I say about this backpack other than... it's perfect for anyone looking for a small but roomy backpack for day trips and/or travel, as its dimensions fall within the carry-on size limits of some airlines! Perfect, I'd say!
