Hydrocollator HotPac Moist Heat Packs

Clinicians in physical therapy, chiropractic, and rehab settings have relied on Hydrocollator HotPacs for decades because they deliver something a dry heating pad can't: deep, penetrating moist heat that relaxes muscle, eases spasm, and prepares tissue for manual therapy or stretching. Each pack holds silicate gel that absorbs and retains water when submerged in a heating unit, then radiates soothing moist heat gradually as it cools against the body.

The Hydrocollator HotPac Moist Heat Pad, Neck Contour (00-1002) is shaped specifically to wrap the cervical spine and shoulders, staying in place where a flat pack would slide off. That contoured fit makes it a go-to for neck stiffness, tension headaches, and post-treatment relaxation, letting the patient sit comfortably while the heat does its work.

A few things buyers usually want to know: these packs are reusable indefinitely with proper care, they must be heated in a Hydrocollator tank of water (not a microwave), and they should be wrapped in several layers of terry toweling before application to protect the skin and control heat transfer. A typical treatment runs 15 to 20 minutes, with the pad reheated between uses in about 30 minutes. Storing the pack submerged keeps the gel hydrated and ready.
