Thermophore MaxHEAT Plus Model 377 Petite Moist Heat Pack 4 x 17 for Neck & Jaw
Thermophore MaxHEAT Plus Moist Heat Pack — Petite 4" × 17" (Model 377)
The petite Thermophore with the Moisture-Plus cover — targeted moist heat for any climate. 4" × 17" strip for neck, jaw (TMJ), sinuses, shoulder, hip, and small joints. Weighted 2 lbs, 3 heat settings up to 165°F, 25-minute auto shutoff. Add a moist cloth in dry or heavily air-conditioned environments. Drug-free pain relief since 1931.
Great if you want to do a localized area on the body — neck, shoulder, hip. Love it!!!
Our Take: The MaxHEAT Plus 377 is the petite Thermophore with the Moisture-Plus cover — a versatile small-format pad for any environment. At 4" × 17" it wraps around the neck, drapes across the jaw for TMJ relief, covers the sinuses, or wraps a single joint. The Moisture-Plus cover produces automatic moist heat in most homes and lets you add a damp cloth in dry or heavily air-conditioned environments. Same 3 heat settings, 25-minute auto shutoff, and 2 lb weighted construction as the standard MaxHEAT 177. For petite size with USA assembly, see the Liberty 177.
Why You'd Choose the MaxHEAT Plus 377
- Produces automatic moist heat from ambient humidity. In dry or heavily air-conditioned environments, add a moist cloth inside the cover for supplemental moisture. The most versatile petite Thermophore cover option.
- The narrow strip wraps the neck, drapes across the jaw for TMJ relief, covers the sinuses, or wraps an elbow, knee, ankle, hip, or wrist. Much more targeted than medium or large pads.
- Three temperature levels with a hands-free switch. Start on Low for sensitive areas like the jaw or sinuses, then step up as needed. Stays on until the 25-minute auto shutoff.
- Reaches 150–165°F — dramatically hotter than generic drugstore pads that max out at 120–140°F. Designed for deep therapeutic moist heat in a compact format.
- At 2 pounds the petite pad maintains full contact on curved areas like the neck, jaw, or joints — keeping heat exactly where you need it without constant repositioning.
- Supports typical heat therapy intervals. Many users treat for 15–20 minutes per session. The auto shutoff provides safety backup so you can relax without monitoring the pad.
- The fleece cover absorbs humidity from the air and the pad's heat converts it to therapeutic steam. In dry environments, the Moisture-Plus cover lets you add a moist cloth for extra moisture.
- The MaxHEAT Plus 377 qualifies for HSA and FSA purchases and may be reimbursable through Medicare or insurance when prescribed for arthritis pain management.

Frequently Asked Questions
What is the difference between the MaxHEAT Plus 377 and the MaxHEAT 177?
Both are 4 by 17 inch petite pads with 3 heat settings, 25-minute auto shutoff, and up to 165°F. The key difference is the cover. The MaxHEAT Plus 377 includes the Moisture-Plus cover that lets you add a moist cloth in dry climates for supplemental moisture. The MaxHEAT 177 has the standard fleece cover that relies entirely on ambient humidity. Both use the same hands-free switch.
What is the Moisture-Plus cover?
The Moisture-Plus cover produces automatic moist heat from ambient humidity like all Thermophore covers. In very dry or heavily air-conditioned environments where there is not enough humidity in the air, the Moisture-Plus cover allows you to add a moist cloth for additional moisture. This makes the 377 the most versatile petite Thermophore for any climate.
What is the MaxHEAT Plus 377 designed for?
The MaxHEAT Plus 377 is a petite 4 by 17 inch pad designed for localized areas like the neck, cervical spine, jaw (TMJ), sinuses, shoulder, hip, and small joints including elbow, knee, ankle, and wrist. The narrow strip wraps around these areas for targeted heat therapy.
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. In very dry environments, the Moisture-Plus cover lets you add a moist cloth for supplemental moisture.
What temperature does the MaxHEAT Plus 377 reach?
The MaxHEAT Plus Model 377 reaches between 150 and 165 degrees Fahrenheit. It has three heat settings: Low, Medium, and High. For comparison, most generic drugstore heating pads max out at 120 to 140 degrees Fahrenheit.
Is the Thermophore MaxHEAT Plus 377 HSA or FSA eligible?
Yes. The Thermophore MaxHEAT Plus Model 377 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. Place it on top of or wrapped around the body area only. Laying on a heating pad can trap heat against the skin and increase the risk of burns. The weighted design keeps the pad in place and maintains full body contact without you laying on it.
