Brief summary: This study is being performed to reduce unwanted fat, in various body areas, using a new applicator and control unit for Zeltiq.

Detailed description: The purpose of this study is to evaluate the safety and feasibility of a new product under development for non-invasive fat reduction. The new product delivers controlled cooling via a conformable surface applicator, rather than the existing vacuum applicator. A range of treatment parameters will be investigated. At the investigator's discretion, each treatment area may receive up to 3 treatments, spaced 2 - 8 weeks apart. The subjects will return for follow-up at 2 months and 4 months after final treatment. Therefore, the entire study period may last up to 8 months.

Eligibility criteria: Inclusion Criteria

* Male or female subjects \> 18 years of age and \< 65 years of age.

* Subject has not had weight change exceeding 10 pounds in the preceding month.
* Subject with body mass index (BMI) between 25 and 35. BMI is defined as weight in pounds multiplied by 703 divided by the square of the height in inches.
* Subject agrees to maintain his/her weight (i.e., within 5 pounds) by not making any major changes in their diet or lifestyle during the course of the study.
* Subject has read and signed a written informed consent form.
