The Catalyst Cryo-Helmet is a device that applies targeted cold therapy to the head. With proper use your Catalyst helmet may be effective in reducing inflammation from head injuries, lowering body heat, and lessening migraine pain.
Catalyst™ Cryo-Helmet package includes:
- Neoprene Shell
- CryoMax™ Cold Packs in UltraCool™ fabric pouches with Velcro
- Insulated carry bag and CryoMAX™ square to keep Cryo-Helmet frozen for hours
To measure head circumference, use a flexible tape measure (or piece of string or ribbon) and measure the distance around the head just above eyebrows and about an inch above the ears. Also consider your overall stature when choosing. You can visit our FAQ page for more information on sizing.
