Alpha Backpack 25L for Nature Photography Waterproof Camera Bag with 15.6 inch Laptop Compartment Tripod Holder Raincover, Blue

The materials are sturdy and just by touching you can feel the quality.
I managed to put massive Tamrons 15-30 and 70-200 G2 and Sigma 150-600 and there was still space for Nikkor 85 in the main compartment. The upper part seems just perfect for Nikon Z6ii with 24-70 f4 on. Side pockets still able to contain a few filters and the upper compartment seems to have some extra space.
Zippers are very smooth and the rain cover is a great extra thing.
What made me quite surprised that when I fully loaded the bag and tried to put it on, the upper-right buckle just unlocked itself and the bag fell down (and one of chest strap hole was torn)! That was a great stress-test to check the durability of the frame (none of lenses broke!) but the buckle thing still makes me feel uneasy. I have no idea why the buckle button releases the lock. The way I put the bag on is not strange or unusual, to be honest. Actually, it unlocked few more times but I was ready - I put the bag on while seated on a couch so the bag just fell on a soft surface.
As I kept on testing the fully loaded bag, the buckle seemed to keep in place. Jumping, walking, fast walking, sudden pulling the handle - in all of the situations it remained locked.
My best guess is the load weight. Although I found no max load specs, I suspect that the gear is just too heavy (8,5 kg to be precise) which is a bummer because all the lenses which are packed, they are needed for my photo trips. Either way, tripod will be carried in a separate bag. I just hope that umbrella and/or water bottle can still fit.

bought the backpack for the holidays. Didn't want to carry the big/heavy camera backpack. Unfortunately the size doesn't quite fit my Nikon D4. But for a short time during the holidays it's okay. The backpack also fits normal DSLRs like the Nikon D7200 perfectly. It also has space for 2 additional lenses up to size 70-200

The backpack is a real space miracle for its size. My Nikon D300 including Tamron 17-50 mm f2.8 + Tamron 70-200mm f2.8 + Tamron 90mm f2.8 and a Nikkor 35mm f1.8 fit easily. and there is still room for a water bottle (e.g. O²) and the additional laptop compartment is also great. a 13" fits in easily. unfortunately without a fabric cover. but good.

Birthday child was happy. The bag made a high-quality impression! Beautiful design and high quality, if you can say that as a layman.

Very nice daypack, optimal size for camera, valuables and more. Zippers work very well. Delivery took place within 24 hours.

This backpack has a well-structured space for everything you need. Would buy him again and would highly recommend him.

real surprise! I use a lot of backpacks, some from such well-known brands as Lowepro, and this one is hands down fantastic! Very spacious (I have a Canon 80d with a 24, a 35, a 50, a 17-85, a 85 and a 70-210, two Cobra flashes and two Cactus v5 transmitters and lots of space installed!! Luxurious zippers and the fabric looks classy. In love with this brand now!!

Excellent bag. Accommodates full frame DSLR as well as 150-500mm, 28-70mm, 50mm lenses with space for filters and accessories etc. The tripod mount is integrated on the side of the bag.

Came from France so it took a while to arrive. But the wait was worth it. Excellent bag. I took all my camera equipment plus 2 iPads. Very pleased.

I am pleasantly surprised by this great backpack, which is a complete device that allows me to fully organize the storage of my camera and accessories (without it being noticed). Thanks!
