Although the SmartSpine© can be used without the protective sleeve, the sleeves are recommended to protect your product from the wear and tear of frequent use.
The sleeve is thin and strong so as to not obscure the shape and the effectiveness of the SmartSpine©. It should be fitted with the seam in the middle, matching the groove of the SmartSpine©.
Each sleeve is custom made from a 100% machine washable cotton and hemp blend. Multiple protective sleeves are available for purchase.
