The Maxpedition Sitka is one of my favorite bags. I carry it everywhere I go in town. I like to adjust the shoulder strap to fit so I can just throw it on and go. After about a week, I need to readjust the strap as it slowly loosens. I came up with this technique to prevent the slipping and to look a little more finished than a half hitch. The half hitch works almost as well and may be preferred with thinner webbing found on many shoulder straps and lightweight backpack waist belts.
