We researched two other companies making the same product and none of their cooling neck ties offer the same surface area. Compared to the two other manufacturers, the Neck Buddies we sell are twice the diameter and  approximately 3" to 4" larger in length. Shown below is one of our Neck Buddies, along side one of our competitors.  Our purple Neck Buddy is 1 1/2" thick, and theirs measures only  3/4" thick.
