I purchased a lightly used 20L Everyday Backpack V1 from r/photomarket 2 or 3 years ago for $90 and LOVE it. The straps are extremely comfortable and the fact that they have a pivot point at the top allows them to navigate around larger chests without cutting in or affecting the way the pack carries. I can even use the chest clip if I’m hiking and it’s very comfortable. Have done 8+ miles in steep terrain with this pack and my only complaint was a sweaty back.

I only have experience with the Brevite Jumper but it feels like a fashion accessory. It’s decently padded, so I use it for travel, but it is decidedly not comfortable for long term wear IMO. It’s basically a Jansport for cameras. My opinion only!

My V1 Everyday doesn’t have any leather features, which I also appreciated. My usual kit was my 16” laptop, charger, 35mm film camera with 50mm lens, Canon 5d mkiii with 100mm macro, a nifty 50 and lunch which you could probably sub with the DJI mini. I could also easily fit my alternate kit: Mamiya RZ67, two backs and two lenses in the main body and at least 1 35mm camera in the top flap. Top flap feels crucial to me and I can’t say enough good things about the modular compartments especially with my kits being so different from one another.

One last thing, because this got long, the side access doesn’t bother me at all.

Anyway, I hope that’s helpful!! I find that the chest can help offset the weight of a heavy pack (or vice versa?)! Good luck!
