I knuckled down for Mark 4, feeling like I was starting all over again. I sized up even more and swapped the zip for a flap. The flap had a tab that could be latched closed when the flap either overhung or the bag was chock-full.
I got so much wonderful feedback about this version, but I just wasn't happy enough with it, functionally. There was a chance of contents being exposed in inclement weather, and it just was crying out to be rolled.
So, in Mark 5, I added a closure that allowed rolling.
But, sob, the front webbing (that black strap) just kept on gapping and the roll wouldn't stay rolled. The idea that I might be so close and have to return to sampling seemed excruciating (and expensive).
How to do rapid testing at home by myself to ensure I was on the right path?
Hand-sewing. I got out a needle and thread and stitched through exterior and lining materials, to see if catching the webbing higher up was an option.
