I ordered from these folks directly, ordering the "extra thick" 100% cotton bands instead of the blend, and was sent the blend ones instead, even though the packing sheet that came with the items clearly indicated the item number for the "extra thick" bands. All attempts to contact their Customer Service have been unsuccessful, so I'm stuck with the blend bands (which are decent, especially for the price as compared with the stuff sold in your typical department or sporting goods store). You're welcome to take your chances, but I'm planning to look elsewhere in the future.
