Such a great product, I have it now in 24L and 18L.
Si spacious and convenient for anything.

I was looking for a daily backpack which I could take as an under-seat bag on a flight and which I could use as an occasional camera bag. Surprisingly there were very few options fitting these conditions and that’s how I came across this backpack. So the boxy shape and size were a big plus for me. I also love being able to access the bag from the front and back. The top compartment is handy for a small camera. Shoulder straps are wide and comfortable. Internal side mesh pockets for a bottle or an umbrella are also very useful (don’t know why more manufacturers have that). Two internal sleeves allow me to fit my laptop and keyboard which is great.
For the next iteration, I would love to see a few improvements. Thicker material overall to make the bag more rigid. It’s a boxy backpack that needs to keep its shape but currently tends to collapse a bit on the back or floor if not fully filled or loaded top heavy. The straps at the top are annoying to undo every time I need to open the top compartment and their loose ends tickle your neck unless tied up. These top straps should be attached to the door of the top pocket itself, not the body of the backpack. Also their hooks should be mirrored instead of pointing in the same direction so that both can be unhooked using both hands at once. The shoulder straps should however be attached to the body of the backpack instead of the rear door. That’s because currently the back of the backpack stretches a bit under load and the top sits further away from the body than it could. Closer fit to the body = more stability. A side access zip would be nice to be able to access a camera from a camera cube or something else from the inside without taking the backpack off. Finally would love seeing the rain cover integrated and a hidden AirTag pocket.

Amazing

Super addition to the ThreePeaks family, same attention to detail and quality, great functionality, all wrapped up in an 18L body.

This is getting closer to the smallest size I’d like, its great as a quick grab bag for a day or overnight.

I’d love one at 12l though, that would be perfect!

Almost perfection. The quality of the bag, the materials and the stitching - awesome. You can tell as soon as you get the package through that it's well built and premium.

For me the slight improvements that could be made would be that the zippers have those little eyelet things on them so you could put a travel lock through them. Then also the straps on the top if they were the other way around so that the long straps fell over the bag rather than your neck/back/shoulder. Another would be if the rain cover could be integrated in some way similar to how I've seen it on a lowepro in the past - although I appreciate in many scenarios not having it there could be beneficial if people think they'll never use it.

Hopefully you can appreciate that these are all extremely minor details and suggestions and that's because every other aspect has been very well thought through and I'd not hesitate to recommend this to someone else and next time I need a different style of bag I'll come back and see if there's something that meets whatever those needs would be.

Great bag that is well made and full of features that looks to be great quality.
