This is the best exercise device I own. 10 pounds of weight perfectly distributed on front and back of chest, in an elastic black vest with orange piping that actually “looks cool.” I strap this on, put my iPhone into the extra front pocket thoughtfully designed in front, and easily walk up to two hours without even feeling the weight. I work up a great sweat, have built up my stamina and strength, and now have four of these stationed for me in locations I often visit: Seattle, Singapore, Boston, Australia.
