Great bag with a few quirks
Overall the 1st Phorm Tacti-Duffle Backpack is a good product for the price. I am currently my second backpack. The first had one of the chest straps reversed and the other side popped off when I tried to adjust the height. The other quirk was around the internal zipper dividers which seemed great for organizing but ultimately came unzipped along the way and the contents ended up melding together. This happened with both backpacks as did the chest strap popping off issue. I would give it a B for overall durability. Customer Service is phenomenal and replaced the first in time for an upcoming weeklong trip. Now the question is whether to keep the replacement.
