Muy practica

Es una mochila fantástica, un tamaño ideal para llevar un equipo completo con ese extra de espacio para guardar otros objetos, como un portátil, chaqueta, y resto de objetos personales, lo cual la hace muy polivalente y práctica. Perfecta como complemento de equipaje de mano en cabina, con el tamaño adecuado para ubicarla bajo el asiento delantero. Muy contenta con la calidad del producto como es de esperar como F stop. Dispongo ya de una Kashmir y está marca no defrauda. Pero sí quiero destacar un pequeño fallo, quizá algo puntual de la pieza que yo tengo. El arnés que se une en el torso por encima del pecho está acabado con un tipo de hilo sedal que me provoca rozaduras en las prendas de vestir y peor aún sobre la propia piel si llevas una camiseta de escote más bajo, de hecho me ha provocado una pequeña herida. Creo que estos detalles deben revisarse mejor.

Guru 4 AIR | 24L - Compact, Durable, and Perfect for Day Trips

This small photography backpack is a great choice for day outings. It features a removable internal camera unit (ICU) that keeps your gear protected and organized. Despite its compact size, it offers enough pockets and compartments to carry all your essentials. The sturdy yet lightweight frame makes it comfortable to wear for extended periods, while its durable build ensures long-lasting use. Ideal for photographers on the move who need functionality without bulk.

I´m a "Guru" now :-)

"This was an excellent purchase. The backpack is of outstanding quality, very lightweight, and made from premium materials. It also has everything I need to carry my camera and lenses. When I need to transport more gear, I use another F-Stop backpack — the Sukha — which is perfect for my medium format camera and additional equipment."

Beautiful, practical, durable, and water proof. Thoughtfully designed with lots of room and the capacity to shape modules to your needs. There’s plenty of room but I wish I had bought a larger one for dual purposes.

Super bag for the city

Got this primarily for a city break in Berlin as I felt that my Tilopa was far bigger than I needed. The bag was perfect. Used it to carry about my Nikon Z6III, 14-30mm and 24-120mm lenses, plus Kase filters. Travel tripod easily carried on the side using strap and net pouch (a feature my Tilopa could have done with). No need for the Gatekeeper straps in my case so I’m glad I didn’t order them. Had spare space in bag for waterproof jacket, baseball cap etc. Even with the travel tripod attached the bag easily met the size criteria for the Ryanair overhead lockers, and I used the smaller underseat bag for toiletries and spare clothes, enough for a 5 day break, so no hold luggage needed. I had been slightly concerned before ordering that the bag might be too ‘stripped back’ in terms of features but had no issues. The included ICU is great, there are internal pouch pockets for batteries and cards etc, and space over the ICU for other items. Very pleased with the bag overall.

I stopped f-in about and bought an F-Stop

I have loads of camera bages - Lowepro's, peli cases, Think Tank bags - I needed a new one - none of the ones i had did what I wanted to do - i needed a bag for every day, a bag i could stuff clean under crackers in to and not take away on trips with me, but not anget the budget airline bag-size police. The F-Stop Guru 4 AIR does all of this. And the addition of the Modular day pack insert thing makes it a bag I am confident of protecting my gear - and pants. I ****** this thing, full of lenses and two mirrorless bodies around London for three days I found it comfortable and adaptable and on some of the guerilla shoots i was doing, required quick access, which the Guru AIR provided through it's pouch. I wish I had bought this bag sooner -
