I got a good amount of this fabric due to it being twice as durable as the vx07 and without the xply grid but when I got it, there were white spots at the edges of the fabric which I couldn't use and had to cut it off and waste fabric. Not only that, if you don't get the minimum order requirement to have this on a roll, it will be insanely creased due to it being folded and good luck getting that out because its not coming out. I feel as though these sheets of v15 have colors printed on them which is evident when you sew through it. The holes have slight white spots revealing the white interior which makes it even less visually appealing. This is a problem that I've never gotten from the vx07 or vx42 and im pretty disappointed. I know these are cosmetic issues but what's the point of you have to waste fabric that you paid for to cut off the white speckles and have white spots throughout the seams after sewing. In terms of durability I am still using a tote I made out of this material so I can't say but I dont know if I'll want to buy anymore of this fabric in a flat color in the future. I know their prym1 camo and so forth helps to take your eye off of those issues which may be a better option but if you want a flat color, I would recommend not to purchase this.
Used this to bake a lightweight frame pack. This fabric looks great and feels durable but It hasn't seen much abuse on the trail yet. One star off because when this fabric is folded sharply it seems to permanently damage it. After ironing (on a really low temperature) the sharpest creases were still visible. Time will tell if these are just cosmetic or will cause structural problems with the pack.
