I know a few others have commented that their DLBCase fits nicely inside their Tri-Star, however I haven't seen any photos highlighting this combination. Therefore I wanted to pass this along for others who were curious.
This first photo shows the front compartment of the Tri-Star fully un-zipped with the DLBCase on top. As you can see the there is a lot of room left. The DLBCase is slightly shorter then my 13 inch brain cell and I feel is a better overall fit.
This photo also shows that my iPad Air fits in the front pocket as well. The website only mentioned an iPad mini for this pocket so I was happy to see I had the option to using this pocket or the one on the other side.
Lastly the second photo shows the DLBCase inside the middle compartment where I normally stow it when I travel for work. Again plenty of room for a down coat or stuff sack.
Overall I feel the DLBCase is an upgrade to my brain cell which I was previously using when carrying my laptop on the road to client sites/work. It still remains very light and minimalistic yet allows for a bit more organization for chargers/papers.
