top strap is 29 in. bottom strap is 12in. comes with extra 24 in strap unattached with velcro. my ice packs work very well on my knees and is designed to work well with or without straps, suits many needs, i tried to check out thoroughly before purchase and would recommend.

Not sure the accurate measurement on the straps but they do have velcro and the straps are expandable. To put into perspective, I’m 5’3″ 135lbs and I put the straps as much as I can tighten them and still need it tighter but it works fine and doesn’t slide down when I walk. I don’t need the cover or straps most of the time bcuz I use it mostly when I’m sitting. see less
