Thermophore Liberty 2 (USA Assembled) Moist Heat Pack — Petite 4" × 17" (Model 177)
The petite Thermophore — USA assembled. Designed for the neck, jaw (TMJ), sinuses, and small joints. Narrow 4" × 17" strip with Velcro fastener wraps and holds securely. Weighted 2 pounds, 3 heat settings up to 150°F, automatic moist heat without water, 25-minute auto shutoff. Assembled in Fremont, Indiana since 1987.
Have a Large Thermophore that has performed very well for more than 30 years. That one is still going strong. When looking for a smaller heating pad, there really was no question as to what brand to purchase. This one is just right for most of my needs now. Thank you.
Our Take: The Liberty 177 is the petite Thermophore for targeted heat on small areas — the neck, jaw (TMJ), sinuses, an elbow, a knee, or an ankle. At 4" × 17" it is a narrow strip that wraps around these areas, and the included Velcro fastener holds it in place for a snug, hands-free fit. At 2 pounds it is lighter than the large models but still weighted enough to maintain solid body contact. It reaches up to 150°F — slightly cooler than the large models because it is designed for sensitive areas where lower temperatures are safer and more comfortable. It has the same 3 heat settings, 25-minute auto shutoff, and automatic moist heat from the fleece cover. Assembled in the USA at the Thermophore facility in Fremont, Indiana. If you want this same petite size at a lower price without USA assembly, the MaxHEAT 177 is the closest lower-cost option. If you need wider coverage for your neck and both shoulders simultaneously, the MaxHEAT Neck & Shoulders pad is the contoured option.
Why You'd Choose the Liberty 177
- The narrow strip wraps the neck, drapes across the jaw for TMJ relief, covers the sinuses, or wraps around an elbow, knee, ankle, or wrist. Much more targeted than medium or large pads. Includes Velcro fastener for a snug fit.
- The Liberty line has been assembled at the Thermophore facility in Fremont, Indiana since 1987. Domestic assembly with American labor standards. This is the petite Liberty option for buyers who prefer USA assembly.
- The long Velcro fastener lets you wrap the pad around a joint or the neck and adjust for a snug fit. The pad stays in place during your therapy session — no holding required.
- Three temperature levels let you dial in the right amount of heat for sensitive areas. Start on Low for the jaw or sinuses, then move to Medium or High for the neck or knee. The pad stays on hands-free until the 25-minute auto shutoff.
- The petite models reach up to 150°F, slightly cooler than the larger pads by design because the neck, jaw, and sinuses are more heat-sensitive than the back or hips.
- At 2 pounds the petite pad is lighter than the large models but still weighted enough to maintain solid body contact. Combined with the Velcro strap, it stays where you place it.
- The fleece cover absorbs humidity from the air and the pad's heat converts it to therapeutic steam. Moist heat penetrates deeper than dry heat without adding water, spray bottles, or damp towels.
- The Liberty 177 qualifies for HSA and FSA purchases and may qualify for reimbursement when prescribed for arthritis pain management.

Frequently Asked Questions
What is the Liberty 177 designed for?
The Liberty 177 is a petite 4 by 17 inch pad designed for the neck, cervical spine, jaw (TMJ), sinuses, and small joints like the elbow, knee, ankle, or wrist. The narrow strip shape wraps around these areas and the included Velcro fastener holds it in place for a snug fit. It is also popular for targeted heat on specific spots of the calf, thigh, or forearm.
What is the difference between the Liberty 177 and the MaxHEAT 177?
The Liberty 177 and MaxHEAT 177 are the same pad with the same features: 4 by 17 inches, 2 pounds, 3 heat settings, up to 150 degrees Fahrenheit, 25-minute auto shutoff, and automatic moist heat. The only difference is where they are assembled. The Liberty 177 is assembled in the USA at the Thermophore facility in Fremont, Indiana. The MaxHEAT 177 is assembled in China at a lower price. Both carry the same 2-year warranty.
Does the Liberty 177 come with a Velcro strap?
Yes. The Liberty 177 includes a long Velcro fastener that allows you to wrap the pad around a joint or the neck and adjust for a snug fit. This keeps the pad in place hands-free during your therapy session.
How does the Thermophore produce moist heat without adding water?
The fleece cover absorbs moisture from the humidity in the surrounding air. When the pad heats up, it activates that moisture into therapeutic steam that penetrates deeper into muscles and joints than dry heat alone. No water, spray bottles, or damp towels are needed. The cover produces moist heat for 20 to 30 minutes, after which it begins to dry out and the pad should be set aside to regain moisture from the air.
What temperature does the Liberty 177 reach?
The Liberty Model 177 reaches up to 150 degrees Fahrenheit. It has three heat settings: Low, Medium, and High. The petite models run slightly cooler than the large models because they are designed for sensitive areas like the neck, jaw, and sinuses where lower temperatures are safer and more comfortable.
Is the Thermophore Liberty 177 HSA or FSA eligible?
Yes. The Thermophore Liberty Model 177 is HSA and FSA eligible. It is also approved for Medicare and insurance reimbursement when prescribed for arthritis pain management. Check with your insurance company to verify reimbursement, which can vary by coverage.
Can I lay on this heating pad?
No. It is not recommended to lay on this or any heating pad. The pad is designed to be placed on top of or wrapped around the body area being treated. Laying on a heating pad can trap heat against the skin and increase the risk of burns. The Velcro strap holds the pad in place without the need to lay on it.
