ADIX Sports - Neck Harness for Weight Lifting, Resistance Training, or Injury Recovery with Long Steel Chain and Neoprene Head Cap, Neck Trainer to Improve Muscle Strength & Fitness

Does the job well enough. However, two points of contention: (1) the D-rings do not stay in position; (2) the chain provided is somewhat weak, I use a thicker chain

I've a relatively small head and this fits snug so would recommend this to others. Velcro adjustment on back of head and chin. Hope this helps!

This has been a great addition to my workout it has help gain 1/2 inch on my neck I throw it in at the end of my workout I got in to neck training after a watching Jeff nippard video on YouTube on how it can help you bench press and he was right great peace of equipment much better than neck curls with a plate

So far so good, comfortable to wear, no rubbing or catching, easy to change the weight
