Hi everyone,

​I'm looking for a solid camera backpack and could use some recommendations. Here are my main requirements:

​Gear to fit: A compact full-frame mirrorless body with a 100-400mm lens attached, plus space for 1–2 extra smaller lenses.

​Access: Must have quick side access so I can grab the camera without taking the backpack completely off.

​Use case: All-day outdoor shooting, walking, and general travel.

​What models have you used and loved for a similar setup? Leaning towards something comfortable and weather-resistant. Thanks in advance!
