We have six Kiefer Neck Collars for sale. They are pre-loved and were only used for 2-hours during Andrea Salzman's Minneapolis seminar this month. These are the same as the Blue Moon collar and are best loved for Bad Ragaz Ring Method. Sewn nylon zippered collar enables adjustment of flotation for each individual while the adjustable belt with clip helps hold the head securely above water for deep water exercise or flotation therapy. These collars are normally $41.25 each but you can get the whole bunch for $150 plus shipping if you call us at 800-860-8624 now.
