Hi,
All of our wraps use one gel at a time however every product comes with multiple gels so that you always have a spare cold and ready. If you require more than 3 gels than you can certainly order additional gels, as an existing customer just call or email one of our King Brand Advisors. If you are a new customer than contact us immediately after making your purchase and we will ship out the additional gel packs with your ColdCure product with no additional shipping charges.
