The smaller size does. The larger size does not. The smaller (6×14 in) has a great strap. It easily wraps around my waist and the Velcro holds well. I can actually walk around and do things with the ice pack on my lower back. It also stays very cold for a long time. I’ve owned several ice packs and this is my best investment thus far. The Cryomax is also good (stays cold a good while) but the strap is not as good and the quality isn’t there. It gets too stiff, as opposed to The Coldest, which is great for wrapping because it stays soft, even thought it’s freezing cold! Search Amazon for “The Coldest,” and you should be able to find the one with the strap.
