As a result of advice I bought this bag then for caching. It is comparable to the Maxpedition Fatboy Versipack S-Type. Apart from the small Handtragegurt, which is not appropriate here. But since one of this bag about one-fifth of paying what Fatboy Versipack costs, which is a top price-performance ratio here. The MFH shoulder bag keeps its promises. I have it in permanent outdoor use, also on partially hard routes, and so far hold all seams, zippers and buckles. For a little over 4 years A top part with enough space for GPS, writing utensils, magnetic grippers, mirror, Stemple, Water Bottle 0.5l, logbooks, 2 flashlights. and on the sides you can still hang small bags off.
