1. Product Overview

It is suitable for conditions such as muscle tension, minor cervical injuries, whiplash, and as a reminder to avoid sudden or painful neck movements.

It is particularly convenient for use during sleep.
2. Key Features
- Limits motion to prevent painful movements during daily wear or sleep.
- Shaped profile designed for chin and jaw comfort.
- Soft comfort padding.
- Breathable cool knit cover.
- Adjustable fit with hook and pile back closure.
- Available in various depths: Narrow 2.5", Average 3.0", and Wide 3.5".
3. Sizing and Fit
How to Measure and Choose Your Size
Proper sizing is crucial for effective support and comfort.
- Measure your neck circumference.
- Measure the depth from the sternal notch to the base of the mandible (jawline) in a straight line. This determines the required collar depth (Narrow 2.5", Average 3.0", or Wide 3.5").
Refer to the sizing chart below to select the appropriate circumference and depth.

For accurate measurements, take measurements first thing in the morning when swelling is least likely to be an issue. Keep the measuring tape in a level position without depressing the skin.
4. Application Instructions
How to Apply the Cervical Collar
- Position the narrowest part of the collar right under the chin.
- Fasten the closure straps at the back of the neck.
- Ensure the collar fits snugly but not so tightly that it causes discomfort or restricts breathing.



5. Care and Maintenance
Cleaning Instructions
To maintain hygiene and extend the life of your cervical collar, follow these care instructions:
- Hand Wash Only: Wash the collar by hand using mild soap and cold water.
- Air Dry: Do not machine wash or tumble dry. Lay flat to air dry away from direct heat or sunlight.
- Do Not Bleach: Avoid using bleach or harsh detergents, as these can damage the material.

6. Troubleshooting
Common Issues and Solutions
- Discomfort or Chafing: Ensure the collar is correctly sized and not too tight. Adjust the hook and pile closure for a comfortable, snug fit. If discomfort persists, consult a healthcare professional.
- Insufficient Support: Verify that the collar's depth (2.5", 3.0", or 3.5") is appropriate for your neck length. If the collar is too short, it may not provide adequate stability. Consider re-measuring and selecting a different depth if necessary.
- Skin Irritation: If skin irritation occurs, ensure the collar is clean and dry. Discontinue use if irritation persists and consult a healthcare professional.
