I've also watched the video and agree with everyone else that this is turning out exceptionally well. A couple of further suggestions: 1. For all compartments that have only one zipper: have a small loop at the closed end so that a small padlock can lock that compartment. For security purposes I like to lock all compartments when I have to put my pack in an overhead compartment, such as are encountered on planes and trains. I have a short cable lock that I can usually thread through all zipper tabs (such as your knotted cords), but since you only have two such single zipper compartments the little tab is a nice additional option. 2. For the short water bottle compartments: I totally understand about being able to open the main compartment fully, but how about a fold-down shirt similar to the one on the main compartment of the Maxpud Fatboy. You could make it so that it stores inside the bottle compartment, but gives extra length, if needed. Frankly when I see short exterior bottle holders I usually stop looking right there: non-functional, regardless of reason, is still non-functional. I do like your idea of the second compression strap, but I think that in addition the fold down skirt is the answer to improving the short bottle holders. 3. On the pack straps: hard to tell for sure, but it appears that the padding is just a little thin. I would opt for just a bit more padding. You may also want to consider a little more padding for the carry handle, too. 4. Pack colors: please also consider the huge military, law enforcement, and hunting markets. In addition to the two tone exterior color scheme you have, I would suggest a darker SINGLE outside color, such as Coyote Brown. For contrast inside have a lighter color, such as desert tan. One or two variations of such solid exterior color combos should be sufficient (otherwise you'll have requests for Chinese Navy camo and Ethiopian Mountain troops camo, etc.). So, perhaps Coyote Brown (outside) and desert tan (inside) as one option and the second option could be black (outside) and a darker grey (inside). As an aside, the diamond threading doesn't seem to be an issue ... Kinda cool, actually. 5. For the bottom of the pack: two thoughts. First, have an additional layer of material, such as 1000d Cordura, as a foot or boot to provide more durability and water resistance to the bottom of the pack. It would go from the bottom up the sides for two or three inches. Second, ensure that there is extra interior padding at the bottom for the area where a computer would rest. That would protect the computer more if accidentally set down too hard. (Great that there's a padded sleeve, but the bottom pad is extra protection.) 6. For the two pockets that hold electronics (cell phone pocket and computer pocket) please consider adding in an elastic strap to secure over the top of these items in the pocket. Again, I really appreciate that they're both padded. 7. The panels for interior pen holders and pockets seem to be a bit flimsy. I've had more than my share of them tear, so I suggest just a bit thicker nylon for those panels. 8. One additional thought on the shoulder straps (and I may have missed this in the video), but I suggest adding in a small 1.5 to 2 inch compartment on each strap. These could be used for storage and easy access to small items such as a vehicle key, lip balm, a whistle, or a Victorinox Classic, etc. Thank you for considering these and all of the other suggestions. I will definitely be a buyer, when you get these ready to go.
