I've been buying similar Dockers straps for years but the sleeves on them break after about two years so I've bought lots of replacements. I haven't had this belt long enough to be sure it won't have similar durability issues, but I don't think it will. It's much stronger and better constructed and just as adjustable as the drawstring around the waist. And it was cheaper than belts of a similar style but of lower quality.
