Does the waist strap on the side effect have loops that you can tuck the excess strap into after you've tighten it around your waist? I find that with cheaper fanny packs, I have a lot of excess strap that just dangles down at my sides. I dont really like that. Also, anyone experience the strap loosening on it's own? It's happened where I bent down to do something, and the straps loosened all by themselves. Thanks.
