I wish that I had the option of 9.5 out of 10, as my review is closer to 5 stars than 4; but a few details warrant addressing.
I love your materials, and designs; they have no plastic materials, fasteners, velcro, or gawdy colors. Your gear is wonderfully reminiscent of the kit of a century ago, as I wish more everyday items were available to us as such.
That being said, some small points of manufacture should be noted. The buckle holes in the ECO Rolltop pack run askew of center. This is visibly noticed, though the buckle tuonges flex enough to accommodate the off centered holes. My Skyline rolltop pack was not completely punched through on the slits of the keyhole punches of the leather top center strap. I quickly remedied that with a small sharp blade and it is fine. However many people would not be as handy, and the stud would not fasten through the strap for them, as it should. I understand how moments add up during production, however this should have been addressed in QC. I have one of your nice dog collars, but matched the buckle holes and punched a few more in between the broad spans of your holes, for a bit more adjustment flexibility. Finally, I edge trimmed all of the packs and collar, for a smoother hand feel of items that I expect many years of personal use and enjoyment from. I hope that I don't sound too fussy with this feedback, and hope that it might be useful. Great stuff folks, and I will buy again and recommend to friends. Sincerely, Nathaniel
