"I have had MS for the last 2 years and was unaware that people with MS are not to get over-heated. Since I enjoy running, biking and the outdoors, the search was on for a "cooling" product. After much web-based searching, Polar Breeze's site caught my attention right away. Very easy to follow, very clear on product description, vast selection and reasonable prices, shipping and return policy very clearly explained. " So far a very trustworthy place to do business with." Brenda B.
